Ticket 2 – HSRP Track
HSRP was configured on DSW1 & DSW2. DSW1 is configured to be active but it does not become active.
Configuration on DSW1:
track 1 ip route 10.1.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
!
track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
!
interface Vlan10
ip address 10.2.1.1 255.255.255.0
standby 10 ip 10.2.1.254
standby 10 priority 200
standby 10 preempt
standby 10 track 1 decrement 60
Answer: (use IPv4 Layer 3 Topology)
On dsw 1 interface vlan 10 mode run:
no standby 10 track 1 decrement 60
standby 10 track 10 decrement 60
(ip for track command not exact for real exam)
Ans1) DSW1
Ans2) HSRP
Ans3) delete the command with track 1 and enter the command with track 10 (standby 10 track 10 decrement 60).
pls, anybody describe me why z command below needed
track 1 ip route 10.28.123.123 255.255.0.0 metric threshold
threshold metric up 1 down 2
tnx
@Tilux
First of all the above command will create a track group number ’1′ which can be called later in our command ‘standby 10 track 1 decrement 60′ (where ’1′ is the group number).
Secondly, according to exam config above command is included with wrong IP address + Wrong Track group + Wrong IP Address. Which I m sure ‘networktut’ will correct soon.
Secondly, as per exam, Cisco created two track groups, 1 and 10 in the config and only group 10 is configured correctly which make sure that DSW1 becomes active HSRP. But in the above TT, whats wrong is that they invoked group ’1′ which is configured wrong(not allowing DSW1 to become active HSRP).
Let me know if any further clarification is required.
Hi!!Naveed.
Why are we tracking the ip address 11.11.11.11 255.255.255.0 in the track 10 ip route 11.11.11.11 255.255.255.0 metric threshold
threshold metric up 63 down 64 command? and why are we calling this command in standby 10 track 10 decrement 60?
Kindly explain.
How do we come to know about the topology to be used out of three in the exam?
I can’t understand how the line “standby 10 track 10 decrement 60″ effects the DSW1 active state. It just decreases the priority from 200 to 140, doesn’t it? That would be useful to get DSW1 to a standby state…
I mean how can this line get DSW1 from standby to active state. By decreasing its priority?!
Oh man, I got it. The matter is that we were tracking the wrong route which couldn’t help us to get DSW1 the active router! “decrement 60″ doesn’t relate this issue at all.
@Dima
kindly explain what did you get?
11.11.11.11 255.255.255.0 10.28.123.123 255.255.0.0
Did these ip address appeared in topology when test?
who can explain it…Thx a lot
Pass yesterday 1000/1000
track 1 ip route 10.1.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
or vice verca didn`t remebmer.
But route you need is locating in the route table on DSW1.
@networktut
Kindly update the track commands as per ‘eLmo’ because same are coming exam.
@All who wants the logic of above configuration
We are enabling tracking for the route to R4 (10.2.21.128 = Loop back address of R4), because if the route towards R4 became inactive for some reason and we no more can access R4 via DSW1 then we want DSW2 to become active HSRP. So we created a track group 10 which not only making sure that DSW2 become active in case DSW1 can’t get us through to R4 but also makes DSW1 again active in case our route from DSW1 become active again. In the above trouble ticket, the issue is that they used wrong track group (i.e. 1 ) which is not configured properly, because its threshold statement is not allowing DSW1 to consider the route towards R4 as active resulting in not becoming an active HSRP but the other track group (i.e. 10) is perfectly configured for the same. Thats why by changing the track group number in the command (i.e ‘standby 10 track 10(not 1) decrement 60′ ) is resolving our issue in the above TT. Following are the explanation of the commands used.
To track the state of an IP route and to enter tracking configuration mode, we are using the ‘track ip route’ command in global configuration mode
track object-number ip route ip-address/prefix-length metric threshold
object-number: Object number that represents the object to be tracked. The range is from 1
to 500.
ip-address: IP subnet address to the route that is being tracked.
/prefix-length: The number of bits that comprise the address prefix. A slash must precede
the value.
metric threshold: Tracks the threshold metric. The default up threshold is 254 and the default down threshold is 255.
A tracked IP-route object is considered up and reachable when a routing-table entry exists for the route and the route is accessible.
To provide a common interface to tracking clients, route metric values are normalized to the range of 0 to 255, where 0 is connected and 255 is inaccessible. The resulting value is compared against threshold
values to determine the tracking state as follows:
• State is up if the scaled metric for that route is less than or equal to the up threshold.
• State is down if the scaled metric for that route is greater than or equal to the down threshold.
We are using the ‘threshold metric’ tracking configuration command to specify a threshold metric other than the default threshold metric.
threshold metric up number down number
up: Specifies the up threshold. The state is up if the scaled metric for that route is less than or equal to the up threshold. The default up threshold is 254.
down: Specifies the down threshold. The state is down if the scaled metric for that
route is greater than or equal to the down threshold. The default down threshold is 255.
number: Threshold value. The range is from 0 to 255.
I hope it would be helpful. Appropriates any relevant questions and comments.
thanks Naveed. U r the best

Thanks eLmo & Naveed
hi Naveed once again thanks for your valuable information
what is the scaled metric how it will compare threshold metric with scaled metric
@ Naveed
Are we tracking the static route or eigrp route in exam
so in case in realtime if we want to track eigrp route how did we mention the threshold value coz eigrp metric are more than 4 digits
or else we can track only static route using track command
@ deva
I ran my head in the wall for about an hour trying to figure out the tracking of the object, finally this website cleared it up for me.
http://jupiter.mcom.fr/~clucas/blog/index.php?article573/hsrp-and-track-object
Basically the EIGRP metric is divided by 2560 to get the lower 0-255 number. You can change that dividing number (resolution) by doing this global command “track resolution ip route eigrp [whatever #]” I had to change the resolution number in my own personal lab in order for the object to track correctly when the link to DSW1 went down.

@ deva
you can view the scaled metric by doing “show track 10″
here is the output from my DSW1 to show you

hi joe thanks a lot now i understand
@ NAVEED
I JUST STARTED STUDYING FOR TROUBLE SHOOT. ( FINAL EXAM IN MY CCNP TRACK).
I DID THE DEMO VERSION OF THIS EXAM. I GOT ALL THE QUESTIONS RIGHT.
One think I noticed was that all the trouble shoot ticket questions are same( except the answers).
so I was wondering If this is true in the real exam ?
Do we have the same Questions for all the tickets or each ticket has a separate troubleshoot question.
To be more clear in the demo version. I have noticed a single unique question for all the tickets.
Client1 can reach some server in the internet (209.xx.xx.xx).
please clear my doubt.
I mean client 1 cannot reach some sever in the internet( 209.xx.xx.xx)
Loopback address of R4 is 10.2.21.128 .So Track 1 is wrong due to wrong loopback address of R4 (10.1.21.128)
this is additional reason
am i correct?
I am good with the tracking and making sure the right group & route is used.
I am want to verify that I am tracking the symptoms correctly. Will it be basically be the client or DSW1 cannot ping R4, but DSW2 can? Also would a correct assumption be that R4 can ping the server?
@Naveed thank you
@networktut Thank you
@Joe
Very nice article on ‘Enhanced Object Tracking’, enough to understand the tracking and scaled route metric. Thanks Joe. Highly recommended for all.
i.e. http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/fthsrptk.html#wp1185135
@Deva
I think Joe already has solved your problem very well by sharing above article. Hope u r already CCNP now.
@Lucky
Read my post on September 1st, 2010 at page 2 of ‘Share your TSHOOT experience’, u’ll get your answer.
@Faiz
Wrong IP address might be a typo mistake here the actual thing is threshold metric.
@RouterJoe
For exam point of view, this question has a exclusive symptom which is its question statement i.e. ‘DSW1 does not become active HSRP’ .
@Dimo
You are most welcome
Naveed,thanks a lot to u.U explained all TTs very well.so its very easy to identify the actual problem.I appriciate u.Thanks again.
@Nav ..thanks for clarifying that for me.
hi,@Joe
i don’t understand what you said that when up,the first-hop interface is fa0/1;when down,the first-hop interface is vlan10.what’s the first-hop interface mean?is the outgoing interface?hope u answer me soon,thx
Hey, I can’t view your site properly within Opera, I actually hope you look into fixing this.
Does anyone know if you can create HSRP on DSW1 and DSW2 in Cisco Packet Tracer?
@Liadoff
Yes you can, in Packet Tracer 5.3. Use ’3560-25PS Multilayer Switch’
hi all,
i know this is gonna sound stupid here…
well can anyone please confirm if the CCIE written exam can act as a prequisite for ccnp and ccip?
cuz i have cleared all the papers for ccnp and ip and have cleared ccie ( 350-001 ) written is that enuf ???
please if possible mail me a reply on rockstar_neo@yahoo.co.uk too..
thanx a ton.

nick
hi all, , track number should be equal to group number??????????????????
if the configuration is
track 1 ip route 10.2.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
i mean it tracks the correct route, but with this conf under int vlan 10
standby 10 track 1 decrement 60
is all thing ok??????????
thanks
to those who passed the exam congrats and i am really confused cuz on cisco site they said there are 35-40 questions in the exam and all who passed they took about 12 tt, 3-4 mcq, and 1-2 DnD so here is where i get confused this all together not more than 20 q ,,is there another lab or just this one big topology for TT
so plz some one post about this and which dump is valid and the link for it
thank u so much guys this site is very helpful
@sara
Track number has no chemistry with HSRP group number. Just, we have to call the same track group which we have created, which is 10 in this TT, However it is a good practice to use the same matching number as the HSRP group number. So, the reason we are changing track 1 to 10 is not because HSRP group number is 10 but because we want to call track 10 not 1. By the way in TSHOOT configuration they have created two track groups (1 & 10) with following configurations.
track 1 ip route 10.1.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
!
track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
Since track 1 will not fulfill our purpose(see above posts for details), we need to change it to track 10.
Sara, I think for this TT, ap direct hi questions py aa gye hu, better to read first all the above posts.
take it with all this god willing shit , half you lot are cheating Muslims.. read the Koran brother and you will see that the profit said ” at the point of stealing, cheating the Muslim is no longer a believer”
you have just become a infidel for the sake of a cert. well done

@Cisco guru
1- Before commenting you should read all the above posts, if it was about cheating then that much discussion wasn’t required.
2- Refer to below Sahih Hadith, which you really needs to know.
Narrated ‘Abdullah bin ‘Amr: The Prophet never used bad language neither a “Fahish nor a Mutafahish. He used to say “The best amongst you are those who have the best manners and character.”
(Sahih Bukhari Volume 4, Book 56, Number 759)
I hope to see some positiveness soon, Inshahallah.
@naveed…
great work man…..
maybe that would kick some sense in him…
Naveed! please do not waste your time replying to this fool. Its very clear “cisco Guru” is just trying to get some attention by posting retarded comments. If he can not spell “prophet” clearly tells me he wouldn’t know anything about “Sahih Bukhari” or any of the Hadith books. You guys are doing an awesome Job. Keep it up!!!.

All,
Thanks for all the help with this. I have Naveed’s post from Sept 26th but I am still confused. How does track group 10 make sure that DSW2 become active? Doesn’t it just decrease the priority by 60 and isn’t the existing priority 200? Can someone help me understand?
in client ipconfig-10.2.1.3,then ping 10.2.1.254 not sucess.
so problem is in asw1 or dswi
check asw1
1. int fa 1/0/1- switchport access vlan 10-if yes
2.int fa 1/0/1-port condition-error disabled-if no
3.int fa 1/0/13 and 23 allowed vlan 10-if yes
NO PROBLEM IN ASW1
THEN GO TO DSW1
check dsw1
1.check VACL or any filter in vlan 10
2.check stand by status of track command is wrong
THESE ARE THE SYMPTOMS
MY DOUBT IS WHICH ALL COMMANDS I CAN USE HERE TO FIND (I MEAN SUPPORT HERE).here the prioblem is HSRP wrong track command.so which command i should use in dsw1 to find the hsrp wrong track .the only show run or any other commands.???
to find the standby track???
hello guys…
i just passed switching yesterday …and i really want to passed this tshoot with understanding..but i don’t where to start…so please anyone …can help me in this…or anyone can have gns3 topology to practice or anything…please …it will be great for me…as i can go back to us and apply for ccnp level job…please…….thank you..and congrates to those who passed..and best of luck to all preparing for it…….
@Nick
heya CCIE written does not count as anything, I found out the hard way, I had a requirement for a job opportunity to get CCNA voice and did not want to do CCNA first as I did that a few years back and let it expire like my CCNP, so I passed CCIE written than wanted to double check, check with test center they did not know, pearson vue did not know, Cisco did not know so had to open a tac case ……….. and after 3 days they phoned me back stating its not a valid prerequisite since its only half an exam actually
so sorry to bring bad news, my advise use the CCNA site from TuT and blaze trough it, it does give a nice feeling afterall to have the recertification done again ! i smiled all day when i got mine in the mail again :)
gl !
Finally, an issue that I am passionate about. I have looked for information of this caliber for the last several hours. Your site is greatly appreciated.
Guys,
Something is not ok with this ticket.
DSW1 will never be active in either situations (track 1 nor track10).Metric threshold will be down as long as we don’t have an exact match with the route from routing table (error: “no route” in the sh track 10 command).After a match is met you can divide the route metric by 2560 to find out if will stay up or not.
R4 will advertise Lo add as 10.2.21.128/32 or 10.2.21.0/24 and here is no match for any of those 2 track routes.
@Joe – How your output say that track 10 is up for that route?
i need some one to tell me if a need to configure any device or only choose please
@ all
1st initially DSW1 is active as it has priority of 200. I think here DSW2′s priority is set at more than 141 but less than 200, because if the track object is below threshold level it will decrease DSW1′s priority to 140 making DSW2 become active.
Now that track object 10 is having upper threshold metric of 63 means, if the route to R4 (ip route 10.2.21.128 255.255.255.0) is having metric of 63 (63 * 2560 = 161280 EIGRP metric value). If that metric value is equal or below 63, DSW1 need to be active.
Now suppose this link’s bandwidth is decreased or delay between the link is increased in a such way that its metric will increase more than 64 (64 * 2560 = 163840), that means track object 10 is down. So DSW1′s priority must be decreased by 60 making DSW2 active.
This is what I understand. Please correct me if I wrong. All persons who took exam, can u confirm all those values correctly?
Thanks.
Case 1: track 1 ip route 10.1.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
The track command creates a track object with id 1 that checks a route to destination 10.1.21.128 255.255.0.0.
It also tells that the scaled metric should be compared with a threshold.
The threshold is a value between 0 -255.
0 is for conecetd and 255 for inaccessible.
So the metric of the route should be converted to the 0-255 range.
As you know different routing protocols uses diferent metrices.
For RIp since the metric value falls withing the range 0-255 its ok.
But for other protocols such as IS-IS,EIGRP etc this is not the case.
So the metrics should be a value between 0-255.
“metric resolution” is used to specify the conversion criteria to convert the metric to scaled metric.
The default criteria is as follows:
STATIC————>10
EIGRP————->2560
OSPF————–>1
IS-IS————->10
Eg:
A change in 2560 in an EIGRP metric result in a change in 1 in the scaled metric.
In the track object 1,the command tells to use threshold of 1 and 2 instead of the default.
Default is “Anything less than or equal to 254 is Up and anything greater than or equal to 255 is down.”
Case 2: track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
The track command creates a track object with 1d 10 that checks a route to destination 10.2.21.128.
It also tells that the scaled metric should be compared with a threshold.
The deault threshold is overwritten with UP 63 and DOWN 64.
Case 3: interface Vlan10
ip address 10.2.1.1 255.255.255.0
standby 10 ip 10.2.1.254
standby 10 priority 200
standby 10 preempt
standby 10 track 1 decrement 60
A track object can be used by clients such as HSRP.VRRP,GLBP etc.
Here the track object 1 is used by the stand by group 10.
Note that standby 10 preempt is used.
When premption is enabled ,it tells the router that it can take the active role in an HSRP group as soon as it has higher priority.
So the first thing is that we have to check weather premption is enabled or not.
You can use show standby command.
In our case premption is enabled, we can directly see it from the configuration.
Then check the route to 10.1.21.128 255.255.0.0.
If its not present in the routing table ,then the stand by priority will be decremented by 60.
In our case the track command is misconfigured.
Instead of tracking a route to 10.2.21.128 255.255.0.0 the admin has mistyped to track 10.1.21.128 255.255.0.0.
You have to check the R4′s loopback address.
SO in our case we dont have a loopback with ip 10.1.21.128 255.255.0.0,so their wont be any route for that destination.
As a result the standby priority for HSRP group 10 is decreased by 60 (meets the down criteria,255>2)and DSW2 is active now.
So we need to modify the command to use the correct destination address for tracking.
The track object 10 tracks the correct destination ,which is the loopback interface on R4,ie,10.2.21.128 255.255.0.0
Now when we use the track object 10, a route is in the routing table for destination 10.2.21.128 255.255.0.0,whose metrics when converted becomes less than 63.
This meets the Up criteria as a result the Standby priority is incremented by 60 and DSW1 can now become active.
Remember that when the track object meets the citeria DOWN decrement of the pririty takes place and when it meets UP increment takes place.
Also in our example we assume that the Hsrp priority of DSW2 is between 140 abd 200,Thats why when DSW1′s priority is decremented by 60 (200-60=140),DSW2 became active.
Use show track object no and show standby on DSW1 and DSW2.
The above informatio seems to be correct according to my knowledge but if its not please correct me.

Hi, Naveen George, Thanks for sharing the knowledge, Could you please forward all relevant,study material about Tshoot to my email, i m plaining to give paper in December it will be very help full , How to start for the same, my ccna is expiring in January i have to clear otherwise i will leave the certification.My email aftabak2004@gmail.com, waiting for your email
@aak2004
will mail u the docs that i have.
i am also preparing for the exam.
will give on december or jan.
all the best.
Did u give any other exam like route or switch.
i think its better to give those first.
@Naveen George
Very nice explanation. Excellent
I’m curious if others have experienced different questions/TT’s than what this site provides as the true questions and answers to what’s on the test. I purchased pass4sure.com’s material and they got everything from networktut.com and it’s all this same material. I’ve seen some post on this site that the exam is exactly what the Q&A’s are given on this site and I’ve seen some other posts with folks saying that the Q&A’s and TT’s are different.
Is it possible that there are other versions of the test or multiple test banks that noone has captured yet? I’m curious because what’s given on this site and the pass4sure material is exactly what I’ve been brushing up on after having read the Cisco press Official Certification Guide and Cisco Press Fundamental as well as watched the CBT Route video’s since the CBT Switch nor CBT TSHOOT video’s have been published/release as of yet!
So does anyone know if there are other versions or questions aside from what networktut.com and pass4sure have here???
Thanks!
@ Naveen & Naveed,
Is DSW2 priority is set between 141 & 200 ?
@ matrix
according to our scenario, the priority on DSW2 must be greater than 140.
The reason is,
from the config you can find that the priority of DSW1 is 200.
When the trace command works ,it decrements its value by 40.
So the priority of DSW1 becomes 140.
Remember that the router with the higher hsrp priority is the active router.
So if DSW1 is not the current active router ,it just means that:
1) DSW2 have a higher priority than DSW1 or
2)premption not configured
In our case premption already configured.So focus on the first case.
Priority of DSW1 =200-60(TRACK)=140 140.
And if DSW2 priority is greater than 200 , then DSW1 wont become active even if the track command meets the UP criteria,that is 140+60=200 :)
Dont get confused by the values.
Try to understand the concepts.
IF DSW1 =200 DSW2 =141
THEN TRACK ON DSW1 TRIGGERS DOWN THRESHOLD
200-60=140
140141
DSW1 ACTIVE
IF DSW1 =200 DSW2=139
THEN TRACK ON DSW1 TRIGGERS DOWN THRESHOLD
200-60=140
140>139
DSW1 IS STILL ACTIVE
IF DSW1=200 DSW2=201
THEN TRACK ON DSW1 TRIGGERS DOWN THRESHOLD
200-60=140
140<201
DSW2 ACTIVE
THEN TRACK ON DSW1 TRIGGERS UP THRESHOLD
140+60=200

@ Naveen, its perfect… thanks….
It’s very interesting. How people share knoledge. I was trying to understand this trak objects several days. I read from top to bottom this full page. It is very cleare to me. I am going to exam with good knowledge and confidence about this topic, even if Question is slightly changed in the exam. no worry. feel can handle.
@Naveen George/Naveed/Joe;
Thanks a lot for good explanations.
Guyz FOR THIS qUESTION CAN ANY ONE EXPLAIN Y ARE WE LOOKING AT LAYER3 TOPOLOGY BUT NOT AT LAYER2/3 TOPOLOGY.
I am really geting confused, What sign/hint/logic/anything takes.
I am confused even after reading all the post in this topic and other Tickets as well.
can any one guide plz
@ Omer,
Here we are basically using L2/L3 topology as its HSRP Troubleshooting. So it involves both Layer 2 & Layer 3 topology. Actually both are similar. Just for simplicity they are divided into 3 parts.
When you find the problem related to switches, you need to refer L2/L3 and if the problem is related to routers, you need to refer L3 routing. Just start troubleshooting with Layer 2 and try to ping each gateway.
hi guys somebody help i am tr to do the demo but there is only 4 tt qu and all releated to l3 topology plz help is there more or just this is it
and how i know this q releated to which topology my cordial thanks to u guys
@Naveen George, your post at 27/11/2010 is an Excellent explanation. now I understand the threshold metric concept much better, thx =)
now to try it out in a real lab..
@meru and all
thanks :) u r always welcome
Hey Naved, you are doing a great job buddy, took some time to understand this one… just one more suggestion, i believe we are using EIGRP if we look at the lay3 Top , so here itself we can say that track 1 is wrong ( even if we consider that the IP address was right ) because it has a threshold of 1 for the UP state, so basically since we are running eigrp, the metric will never be less than or equal to 1 , since it is always a huge metric… and hence it will always be a down state… Hope i am right….
sorry buddy… i guess i missed one more name.. @ Naveen & Network TUT
summary for this:
1) if the route for track 10 is reachable, meaning it us UP. But it depends on how you declare the UP value. ie. if reachable and ur UP value let say 10 and down value = 11, then the result metric threshold 15. even if it is reachable it is considered DOWN because down value 11 < 15. it triggers the standby to decrement.
solution: change the UP value = 15 and Down value = 16, so it will not trigger the decrement since it is reachable.
2) in case the route for track is truly down, it shud decrement the priority value and when happens DSW2 priority value shud be greater than decremented DSW1 priority….
@all nswer: (use IPv4 Layer 3 Topology)
On dsw 1 interface vlan 10 mode run:
no standby 10 track 1 decrement 60
standby 10 track 10 decrement 60
(ip for track command not exact for real exam)
is answer is as above ….den wht is this in …scenario ???
Ans1) DSW1
Ans2) HSRP
Ans3) delete the command with track 1 and enter the command with track 10 (standby 10 track 10 decrement 60).
Hi,
In my exam i didn’t find any HSRP config in DSW1&2, and sh standby cmd is not working
interface Vlan10
ip address 10.2.1.1 255.255.255.0
standby 10 ip 10.2.1.254
standby 10 priority 200
standby 10 preempt
standby 10 track 1 decrement 60
so what will be a problem
good job guys guys:)
@kumar
As stated in your posting, the following are confg on HSRP:
standby 10 ip 10.2.1.254
standby 10 priority 200
standby 10 preempt
standby 10 track 1 decrement 60
@all
regarding metric threshold, it is definitely wrong!!!!
track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
this is wrong, why? how can you know the exact up 63 and down 64? if using EIGRP.
using show track command, so why putting up 63 and down 64 without verifying first this command?
hope you understand the concept on how to trigger the priority…. thnx.
Hey guys,
I’m preparing for the TSHOOT exam and therefore built a lab exactly like described in the topologies supplied by this website.
But the track 10 object won’t come up! “show track” says:
Track 1
IP route 10.1.21.128 255.255.0.0 metric threshold
Metric threshold is Down (no route)
1 change, last change 01:29:30
Metric threshold down 2 up 1
First-hop interface is unknown
Track 10
IP route 10.2.21.128 255.255.255.0 metric threshold
Metric threshold is Down (no route)
1 change, last change 00:00:51
Metric threshold down 64 up 63
First-hop interface is unknown
Tracked by:
HSRP Vlan10 10
Like “marxs” said on 2010/25/11, there’s something wrong.
So what is the configuration of R4′s Loopback0 Interface? I think it’s “ip address 10.2.21.128 255.255.255.0″.
On DSW1 there route appears in the routing table as follows:
D 10.2.21.0/24 [90/156160] via 10.1.4.5, 01:22:28, GigabitEthernet1/0/1
When I look for the route with
“show ip route 10.2.21.128″
the output says that the route is successfully installed.
But why does the track 10 object not come up?
When I create a track new object with “10.2.21.0 255.255.255.0″, the object comes up.
thx tom
@Tom,
Just my 2c.
R4 loopback IP should be 10.2.21.129.
Are u able to PING 10.2.21.129?
In DSW1 & 2, ‘show ip route’ will show a route to subnet ’10.2.21.128′
Track 10 track ’10.2.21.128′ subnet, by right, ‘show track 10′ will show ‘Track 10′ is up.
Pls note that ‘show track #’ is not supported in Exam.
In my opinion, Track 1 will never be Up. Even the IP Route that it track is Up. As the up metric need to be <1. Even the lowest metric, which is static route is '1'. There is no way that a metric can <1.
I heard a 'rumour' that in the context of exam, 'Track 1' & 'Track 10' may not be present in DSW2. For DSW1, check carefully which track is specified under 'standby 10 track # decrement 60'.
@david
DSW1 is an Active Router, so putting the route should be in DSW1.
Meaning the active path is Client1 => ASW1=> DSW1 => R4 => R3 => R2 => R1 => ISP=>Web
So putting the tracking should be better to only 1 router for clarity and preferred to put in active router.
In exam it doesnt matter since you cannot able to use the track command.
back to the question why DSW1 cannot be active?
@kaibigan
Thanks.
DSW1 cannot be active because DSW1 priority in standby group 10 was reduced from 200 to 140, as the result of Track 1 was Down.
—–
standby 10 ip 10.2.1.254
standby 10 priority 200
standby 10 preempt
standby 10 track 1 decrement 60
—-
After we change to track 10, the result of Track 10 is Up, hence DSW1 priority did not decrease & it maintain the Active router for standby 10.
The priority of DSW2 is 150.
hi can someone kind enough to send screen shot for all the tticket to my email??
suaveguy28@yahoo.com.sg. million thanks.
@ all:
can any body tell me which tickets are valid dump for exam, am going to attend the exam next week,
please help me , u can send that valid dump to my email address KRKR83@hotmail.com
thanks alot
Who can explain this command for me?
track 1 ip route 10.1.21.128 255.255.0.0 metric threshold
threshold metric up 1 down 2
!
track 10 ip route 10.2.21.128 255.255.255.0 metric threshold
threshold metric up 63 down 64
I don’t understand what they mean.
I just passed with 1000/1000! Thanks a lot networktut! You’ve done a great job!
At the HSRP Ticket I specially focused on the route which is tracked. The track commands in the ticket are as follows:
>>>
track 1 ip route 10.1.21.128 255.255.255.224 metric threshold
threshold metric up 1 down 2
!
track 10 ip route 10.2.21.128 255.255.255.224 metric threshold
threshold metric up 63 down 64
<<<
Which means that the masks are the same, only the second octet and the threshold values differ.
Thx Tom
Hi,
Dear All, I need help.. I have planned to give a tshoot paper… does anybody have exam material at which i can practice… plz response… i am bit wory about my exam..
Regards,
Muhammad Waseem.
eLmo explains is right
All the answers for Tickets are wrong just one week ago I did the TSHOOT Exam and I wrote the same answer but I failed. We need to study well to pass and learn how to find the answer
@All please illd like to knw if the Tshoot exam questions and answers here are still valid,any one who did it recently should please update asap.Thanks
Hi everyone! I’m going to take the exam next week. Guys please let me know if there is anything changed or updated.
Are these questions still valid?
Please help me……!
Thank you
This web site is mostly a walk-by for all the data you wished about this and didnt know who to ask. Glimpse right here, and also youll undoubtedly discover it.
Youre so cool! I dont suppose Ive learn anything like this before. So nice to find someone with some unique thoughts on this subject. realy thanks for beginning this up. this website is something that’s wanted on the internet, somebody with slightly originality. useful job for bringing one thing new to the web!
I did the exam yesterday and got 1000……………..!
Thanks for everybody here supporting me for this achievement.
All the questions in the exam are the things appear here. Nothing has been changed.
But i would like to give an important advice for the people who wish to take the exam soon.
Please read the comments in following link by Geno and Lisa. Those instructions were really
helpful to me…!
http://www.networktut.com/tshoot-ticket-1
Regarding this ticket we should use track 10 cause the loopback address in it is the loopback address of R4
This really answered my drawback, thanks!
Dear All;
just passed Tshoot,& um CCNP.Got 1000 ;i ve got the following:
4 MCQ
NO Drag & Drop.
12 TT (1 new TT,the old TT with wrong ip 209.56.200.241 has been removed)all other TT are VALID.
Thanks Networktut for charing knowledge.
@Ahmaaaad
Can u please provide me Thsoot dumps, Please Reply
Thanks
@Nirmala
can please send me the dumps for Tshoot.
Thanks
Hi,
can some one please tell me the actual question count Tshoot dumps, Testinisde and tes1pass show the question 226 how ever exam collection dumps shows some where 50, please some clarify this to me.
Thanks
Confirmed David’s remark from December:
When DSW1 is configured to track 1 the IP address is not valid (10.1.21.128 is not in the routing table), therefore tracking fails and the original HSRP priority value is decremented by 60 (from 200 to 140). Since the priority value of DSW2 is set to 150 it will be the active ‘router’.
In case of tracking 10 the IP address is valid (10.2.21.128/27 loopback address subnet on R4) therefore the HSRP priority value of DSW1 won’t be decremented and will maintain the value of 200 thus having the active role.
Please note the above is not affecting the reachability of the Web Server from the client PCs, it works in each case.
Bambulka explained it so simply. Other explanations seems over convoluted.
Has anyone seen the TSHOOT 642-832 Dump for Testinside? It has not Trouble tickets questions. Something is really wrong there…
They are almost cheating to people
The 642-832 TSHOOT Topology made available by cisco on the PDF is not the same as their online Topology demo. Could someone please confirm the actually topology used in the real exam?
This forum is 2 slow
Knock Knock! anybody home? The forum’s too slow
Bambulka’s explanation above is NOT CORRECT.
The statement with track 1 has NO EFFECT on DSW1 as active/standby HSRP router since it is referring to WRONG track#.
“Tracking fails bcz of invalid address and therefore HSRP priority value decreases by 60″ is WRONG- bcz although tracking fails, that means that the statement DOES NOT TAKE EFFECT and priority DOES NOT DECREASE.
Also pls read Naveed’s comments from Sep 26.
Can anybody give me an example of exactly how the TT Questions are asked i the exam?
hey guys
have the odd case in my tshoot test lab that I see the eigrp route to 10.2.21.128/27, but my tracking always says “no route”…

Hi, I had the same issues. As soon as I changed the loopback IP as well as the tracking statement to /24 subnet mask everything went well!
Hope that helps!
Hey guys …..
A big thanks to all u guys out there …
One thing i want to knw …
Is it required that we fix the issue s ….or just identify them and anwser the questions theer after ?
Just start’d prep 4 tshoot.
Very insightful blog
Thanks alot guys
esp ‘Tut. Naveed u the best.
@tom
Just answers are required … the configure terminal it’s out of reach (I think the simulator displays “command not implemented”)
@Abraxas
thx for the reply.
I tested the config I did on R4 and DSW1 out with two GNS routers and all worked as I expected… those 3550s I have are rubbish!
so u say u configured loopback as 10.2.21.129/24 and see route 10.2.21.0/24 on DSW1 which you can track successfully?
How do you distribute the loopback on R4? via redistribute static or via network command under eigrp?
thx again
Does the CCNP 642-832 TSHOOT exam ROUTERS and SWITCHES resetS themselves, or do we have logout of all DEVICES after every Trouble Ticket?
How does the routers refreshes themselves between trouble tickets
Hello everybody, I did the test today with 930/1000 – there is a tt of bgp and drag drop a question that is not available on the site that went into my exam, the rest are equal.

I have completed my CCNP certification today by passing my last exam TSHOOP.
The exam itself was kind of straight forward with almost all of the TT well know
as state on this site. I had 2 DD, 2 MCQ & 13 TT
One of the issues with this TSHOOP exam is that you have to constantly move windows around whiles you are trying to keep your concentration. I was also working on small screen. (Frustrating)
TIP
Have a strategy with your PING command
Make sure you properly exit all devices after each ticket.
Abort and move to the next TT if you can’t find the problem. (You can always come back)
I think cisco should have offered a PRINT OUT OF THE TOPOLOGY to all candidates on exam day and collect them afterwards. Anyway! I have a good dump. Interested? Drop me a line donald.bart-williams@stjohns.surrey.sch.uk
I am now going to be focus on ASA5510 firewall
To all you CCNP Candidates on this forum including SWITCH & ROUTE, Good Luck and have a nice summer. It has been fun
@Naveed / @All
how do i catch this problem .. if client 1 doesnt ping DSW1 ?
Hi,
I have been reading all the comments however i still couldnt find the answer of my question.
From the Pass4sure software, it says
track 1 ip route 10.2.21.128 255.255.255.224 metric threshold
threshold metric up 1 down 2
track 10 ip route 10.1.21.128 255.255.255.224 metric threshold
threshold metric up 61 down 62
Question is simple – what is the actul loopback address of R4 i.e. is it 10.2.21.128 OR 10.1.21.128?
Thanks
If that router goes down you have nothing.With HSRP youd need to track an IP on the far side of the MPLS cloud to ensure end to end reachability. If that router goes down you have nothing.With HSRP youd need to track an IP on the far side of the MPLS cloud to ensure end to end reachability. This is how it would work with a layer 3 switch-If the switch was not a layer 3 switch and the routers were the default gateway the track ip route feature could be used more info or with HSRP track command -The config would look something like this-Code !!!
hi guys
Are flitering commands working on this exam.also guys as per TT is it well written that as DSW is not going active to or you have to figure out wats wrong.
you help is highly appreciated taling my Tshoot on Tuessay 31 dont wanna go in darkness the concept is in
hi naveed i need material of ccnp tshoot if any one having real topology or gns3 lab plz mail me at gr_jaweed@yahoo.com
hey guys!! can somebody please tell me about the t-shoot tickets!! i mean do we have to correct them by entering the right configuration commands or is it in multiple choice just like the rest of the questions???
Any changes in the current dumps?????
I understand the ticked, but:
Why can’t you connect to the website thought DSW2?
Or does this TT have a different task to begin with?

D 10.2.21.0/24 [90/156160] via 10.1.4.5, 00:00:55, FastEthernet0/1
156160/2560 = 61
I am using 3550 for DSW1 just like mr.muschnik, so maybe the 3550s are the problem.

“When I create a track new object with “10.2.21.0 255.255.255.0″, the object comes up.”
I tried it with both 10.2.21.128 255.255.255.0 and with 10.2.21.0 255.255.255.0 in the tracking object statement and I still get “(no route)”

hi guys
I am going to write my exam soon, and i want to know exately how standby 10 track 10 decrement 60 command do. the threshold up value is 63 and down is 64, so when the route to R4 loopback is not accessible, the HSRP priority will become 140, now my question is that what the relation between this 140 and the up threshold value 63?
please someone help me as soon as possible

ayman- The value 63 refers to the value of the metric of the route when it is still considered ok by hsrp
I tried and it works with GNS3, but i have to set DSW1 with track resolution (http://jupiter.mcom.fr/~clucas/blog/index.php?article573/hsrp-and-track-object)
…I hope it is correct ..my exam is tomorrow :(
