Ticket 12 – IPv6 OSPF

Kindly update the question statement. The above mentioned not as per the exam. Although the problem lies in R2 but they asked question for R1.

Question: IPv6 loopback cannot ping the IPv6 loopback of DSW2.
Situation:- R2 can’t establish neighborship relation with R3 because it dose not have any interfaces enabled in Area 0.

Symptoms:-
1- IPv6 ping from R1 to DSW1′s loopback will timeout
2- IPv6 ping from R2 to DSW1′s loopback will timeout
3- You will not see R3 as neighbor on R2 by entering ‘ipv6 ospf neighbor’ command
4- By entering the command ‘sh run’ you will not see ‘ipv6 ospf 6 area 0′ command under the interface S0/0/0.23 on R2.

Great Job uTut. Well revise the exam again.

Heyyy Cisco TAC.. Please leave us..!! You do revise man, still we will do these “Great Jobs”..! Kudos NetworkTut..!!

Hey Cisco TAC, you’d better make Cisco exams more fair. It’s too often that we face questions which can not be answered properly without taking a look at dumps or smth like that. Nobody remembers the details which sometimes Cisco requires to be remembered to pass the exams.
The same story with TSHOOT MCQ and D’n'D questions. It’s absolutely useless to remember things like those from these questions.

But I believe you’re just a cheater!

Hi,

I don’t understand why :

1- IPv6 ping from R1 to DSW1′s loopback will timeout
2- IPv6 ping from R2 to DSW1′s loopback will timeout

In fact, I need more explanations for this TT …

Hi
How we can know
IPV6 loopback of R2 cannot be pinged from DSW1’s loopback
in this Q…???

@Naveed first I want to thank you for the great help. secondly, in the reall exam will the symtoms which you right at the top will be the same as direct? as an example you mentioned:

Symptoms:-
1- IPv6 ping from R1 to DSW1′s loopback will timeout
2- IPv6 ping from R2 to DSW1′s loopback will timeout
3- You will not see R3 as neighbor on R2 by entering ‘ipv6 ospf neighbor’ command
4- By entering the command ‘sh run’ you will not see ‘ipv6 ospf 6 area 0′ command under the interface S0/0/0.23 on R2.

Will the above shows exactly as in the exam as Ticket symtoms??

@Dimo
Yes, those are as per TSHOOT exam.

@anuloma_viloma
Read carefully the ‘situation’ in my first post to get the reply of your ‘why’. If still you are unable to get it, let me know where u r getting struck.

@Mustafa
You can use extended ping from console. By using extended ping we can define which source address to use for ping among all of our IP address assigned to various interfaces. By default in normal ping it is using the source address of egress(exit) interface.

I had been arguing with my close friend on this issue for quite a while, base on your ideas prove that I am right, let me show him your webpage then I am sure it must make him buy me a drink, lol, thanks.

k tell me one thing tht the question is mentioned in the same way as listed below at the real exam or we hv to find it by our own if its ipv4 or ipv6 scenerio??

Question: IPv6 loopback cannot ping the IPv6 loopback of DSW2.

@Ayesha
This TT has a exclusive question statement, which is enough to recognize it. i.e. “IPv6 loopback of R1 cannot ping the IPv6 loopback of DSW2″

pls mr naveed.

what about if the client, Dsw1,Asw1,and all the Routers can ping the server, What wil b the problem? And where will be the problem/

Very enlightening and beneficial to someone whose been out of the circuit for a long time.

- Kris

@serious
If all can ping the server, then you are on IPV6 TT and pinging across IPv4 addresses ;) . Problem and symptoms are already defined above for this TT.

@Naveed
Question: IPv6 loopback cannot ping the IPv6 loopback of DSW2 OR DSW1

@Ayesha
Initially people said that it was ‘DSW1′, later on people reported that it has been changed to ‘DSW2′, also in my exam it was appeared as ‘DSW2′. Any how, either they asked for ‘DSW1′ or ‘DSW2′, it doesn’t make any difference. Since in both cases, Symptoms, Problem and Solution is same. Just try to get the concept.

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

S0/0/0.23 is the connectivity from R2 to R3?

Hi guys I am re-taking the exam today, I will post may comments and score later on. Thanks

Could anybody explain what is the purpose of the GRE tunnel between R3 and R4?
OSPFv3 is running betweend R3 and R4, on R4 there is mutual redistribution, so what’s the point?

OK, got it ;)

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

@naggi

It’s a DEMO only, so you can’t expect the exam exactly as what the demo is..I’ll give you a clue, the topic in this website talks about TSHOOT..dig into it..:)

Hi I found your site by mistake when i was searching Google for this issue, I have to say your site is really helpful I also love the theme, its amazing!. I dont have that much time to read all your post at the moment but I have bookmarked it and also add your RSS feeds. I will be back in a day or two. thanks for a great site.

Hi I found your site this morning by mistake when I was searching Google for some Vlan filter issue; I must say your website is great. I have my TT exams in 2 hrs and hopefully i have gained some added knowledge to take with me. Thanks for a great site.

Guys passed the TT exam on Dec 17 with 1000/1000, Thanks .

lukey hw many labs came n hw many questn is it in total pls this is my mail stylow400@yahoo.ca am writing on 23-12-2010, pls hep n wch dumbs did u use……i will be expectin ur reply as soon as possible.thanks.

Naveed pls is it only the tt,dnd nd mcq that came out in the real exam no mre no less pls reply urgently…….

Hello Lukey.
Please tell me how many TT’s were there. which dump u have gone through.
I have booked my Tshoot on 27.12.10.
I am totally dependent on Networktut.

Could anybody explain

What is the purpose of the GRE tunnel between R3 and R4?
OSPFv3 is running between R3 and R4, on R4 there is mutual redistribution, so what’s the point?

PLEASSSEEEE!!!!

@Naveed @Networktut

What is the purpose of the GRE tunnel between R3 and R4?
OSPFv3 is running between R3 and R4, on R4 there is mutual redistribution, so what’s the point?

@From Matrix

I think here GRE tunnel between R3 and R4 is used so to use existing IPv4 network for IPv6 routing using OSPFv3…. Routers R3 & R4 are IPv6 capable, but network between them may not capable of handling IPv6….

In practical sometimes we can not change existing IPV4 network directly to IPv6…. So its practical implementation of IPv6 where existing IPv4 network is still used for IPv6 routing by creating tunnel, so IPv6 packets are encapsulated in IPv4 packets and later at R3 it is decapsulated….

For this last questions, we keep the same topology but with different addresses now in IPv6.
I assume all preceding IPv4 don’t appear in the sh run of the routers.
Am I right?

@Grabs,

No, all the IPv4 & IPv6 config are visible in routers on ALL 12 TT.

But in EACH TT, there will config that is:
-enter wrongly [misconfigured] or missing

The trick is to identify it:-). 1 way is to compare config of suspected mis-configured device in a few tickets.

Though i acknowledge that this may not sound a ‘genuine’ way to pass Tshoot.

But, after spending time in studying the relevant Cisco books, student materials etc….i learnt that it ‘smarter’ to practise the Cisco Tshoot demo site & this forum.

cisco guru teri maa ki choot .. madarchod.. randi k bacche..

12tt are objective questions or we want to enter the specific command and MCQ are the same one in networktut.

Any body pls help me i am going for the exam tomorrow. pls help me.

@Kirandeep

objective r come exam in each question..pls explain……thks advs…

GRE Tunnel is just one of the IPv6 Tunneling methods. My understanding why they used GRE tunnels to encapsulate IPv6 within an IPv4 packet using IPv4 as the destination and source ip of both tunnels because not all of the devices on the network topology support IPv6. Through GRE tunnel, communication between IPv4 and IPv6 devices is possible.

Someone may correct me if I am wrong.

@Helterskelter

The tunnel that you mencioned is the 6to4Tunnel, the traffic is sending throught the tunnel like an ipv4 traffic and descapsulated in ipv6. Rgds,

part of R2 ipv6 configuration:

R2(config)#ipv6 unicast-routing
R2(config)# ipv6 router ospf 6
R2(config-rtr)#router-id 2.2.2.2
R2(config-rtr)#exit
R2(config)#interface s0/0/0/0.23
R2(config-if)#ipv6 address 2026::1:1/122
R2(config-if)#ipv6 ospf 6 area 0
R2(config-if)#int s0/0/0/0.12
R2(config-if)#ipv6 address 2026::12:2/122
R2(config-if)#ipv6 ospf 6 area 12

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

1st of all a million’s of thank to ALLAH,,than all those who contribute and provide helping stuff and in last thanks networktut.com.

i really enjoy the exam it different,it logical,it full of knowledge.i love CISCO.
dera maza ye vokta.

i passed my exam today and got 928/1000 score.
any one have any Q’s,,,its my pleasure to answer you and help you.

thanx once again

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…!

I just passed TSHOOT 982/1000, thank you to Networktut and Naveed for your support. You can expect some donation from me as soon as I get my pay. I urge all other folks who are benifiting from this site to do the same. Please donate what ever you can afford to keep the site running.

I missed one answer on NTP server in multiple choice question:
If two ntp server ip addresses are configured, which ntp server will the router use?
Can’t remember all the choices but one was router with lowest mac address (I didn’t pick it).

Also question of IPV6 is slightly different. The wording was R1 loopback IPV6 is unable to ping DSW1 IPV6 loopback. The way I tackled this was to verify each router interface is configured for IPV6 ospf. In my case R2 interface s0/0/0/0.23 didn’t have IPV6 ospf configuration.

Hello All,
Want to clarify one thing, all TT except two have the same problem description “client 1 (or client 1 & client 2) can’t access the webserver 209.65.200.241. So start with the client and see if the client has ip address and gateway via dhcp. If the client has 169.XX.XX.XX ip address then it is likely to be ASW1 (port not in Vlan 10, vlan filter, port channel problem).
If the client has correct IP address and gateway then start pinging one hop at a time.

The remaining 2 TTS:
One explicitly mentions IPV6 so you know what might be the issue here.
Second mentions DSW1 not active in HSRP config so you know where to go for this.

Hope this helps.

Sorry one correction

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.

@AhMAAAAADD
May I know what is the situation about your “1 new TT”? And someone has mentioned NTP. Is it in TT or MCQ about NTP ?

Thanks !

Hello, maybe I am dump but on this ques: do you type command “ipv6 ospf 6 area 12″ on R2 and then give answer R2 for 1st question and 2nd question: OSPFv3 and 3rd answer
ipv6 ospf 6 area 0

Thanks

Hi Confused,

you don’t have to type the command remember you don’t have to resolve the TT’s but you do need to correctly analyse the cause of the problem. You will be presented with Three lots of multiple choice Q’s for each ticket the first asking what the device at fault is i.e. R1 or DSW1, the second asking what the technology at fault is i.e. BGP or NAT ect, and the third asking what will reolve the problem i.e. issue a command. Hope this helps. Does anyone know what the new TT is that replaced BGP (incorrect neighbor statement)

@ muum ,,,, your wording sounds like you are Pukhtun .. please reply when you read my message please .. dayra manana …

Enabling OSPF for IPv6 on an interface will cause a routing process and its associated configuration to be created. In OSPF for IPv6 each interface must be enabled using commands in interface configuration mode. This feature is different from OSPF version 2 in which interfaces are indirectly enabled using the router configuration mode.

Guys
For IP helper address use something like this
Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface vlan 10

Switch(config-if)# ip address 10.2.1.1 255.255.255.0

Switch(config-if)# ip helper-address 10.1.4.5

Switch(config-if)# exit

Switch(config)# interface range gigabitethernet0/1 – 2

Switch(config-if)# switchport mode access

Switch(config-if)# switchport access vlan 10

Switch(config-if)# exit

Great Blog. I add this Blog to my bookmarks.

Very informative post. Thanks for taking the time to share your view with us.

hi muum,

pls give your mail id, so that i can ask some questions with you?

u r wonderful man … need not to say … do not contribute … continue ur well thought bringing up … instead of learning … guess … u need to reinitialize … in ur IOS … u r way ahead of the crowd … so take a break … go to HAWAII … and say aloha with dancing wolf..!

kindly can any one send for me link to download from it the latest pass4sure v 8.3/50 Q my email is lina.alaa49@yahoo.com

thanks in advance

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?

topology available on pdf from cisco is the exact one used in real exam….ignore topology demo….

Can any one tell me whether the ipv6 ospf TT answer is it
1. R1
2. ipv4 ospf or ipv6 ospf?????

i guess its IPV6 ospf but its not mentioned clearly in this TT.

If two NTP addresses are configured without “prefer” at the end….. router will use lowest NTP ip address

IPV6 communication between R1′s serial interface and R2′s sub interface is it realy possible?
on R1′s serial interface you can use “FRAME-RELAY MAP IP 2026::12:2 102″
BUT
on R2′s sub interface You cnat use the simmilar command, because sub interface does’t supports frame-relay mapping, and
frame-relay interface-dlci doesnot suppots ipv6.
IS there any possible solutions for it.

Can anybody give me an example of exactly how the TT Questions are asked i the exam?

Does the CCNP 642-832 TSHOOT exam ROUTERS and SWITCHES resets themselves, or do we have to logout of all DEVICES after each Trouble Ticket?

r this tickets r valid ………………….

What?

How does the routers refreshes themselves between trouble tickets?

clear TShoot today 876/1000 .Thanks to netwokut ..
1 TT IPv6 has been changed.so be carefull

What is the IPV6 change

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.
Thank you!

Auto-creation of OSPF areas is supported so an OSPF area does not have to be defined before assigning it to an interface. The hello-interval ospf virtual link interface configuration command specifies the interval between hello packets that the software sends on the OSPF virtual link interface. The following example specifies the interval between hello packets that the software sends on the OSPF virtual link interface as 100…..

@sub / felcor any details/pointers on the new TTs any info will help taking soon
thanks

Thankyou very much

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

Hay guys can i troubleshoot all tickets by just viewing the running configuration command while using strategy given by ENA on Top.

Please help

All my Dears, friend and brother.I have a problum my TSHOOT Paper exam date 5-July-2011

Thanks For This Post, was added to my bookmarks.

You certainly have some agreeable opinions and views. Your blog provides a fresh look at the subject.

I am having a problem issuing the command : ping ipv6 on Packet Tracer,
is it even available there ?

I failedd the exam two days ago and there is no IPV6 ticket.

Meera what was the problem and have the tickets chnaged. Were u understanding the concepts

2012:FEED:CAFE::/64

:-),

gZtB8B Sometimes I also see something like this, but earlier I didn`t pay much attention to this!….

How can I know this ticket in TSHOOT exam? (in the question mentioned IPv6 yes or no).

Today, I have passed TSHOOT with full mark Alhamdulleah (thanks for GOD). All the dumps are valid.

13 TT (EIGRP AS ticket is not in the exam).

All 13 TT is the same.

you know this ticket via the question, it is asking about trouble via IPv6.

Going for the exam tomorrow. Anynew Questions MCQS OR DDs

Awesome blog you have here but I was wondering if you knew of any discussion boards that cover the same topics discussed here? I’d really love to be a part of online community where I can get suggestions from other experienced individuals that share the same interest. If you have any recommendations, please let me know. Thanks a lot!

am having the exam 2morow, since we have d same topology for all d tickets, does each ticket have its own unique problem in the topology, cos in d exam demo the topology configuration errors were the same for all 4 tickets

Dear All,

I nned your Help for Tshoo 642-832 .On this Thursday i have my exam .pls some can tell me about the question how it comes in the simulater .does it ask this or this problem is ther or only it will say Client 1 cannot ping web server and pls tell me what is the exact way to solve the problem

Passed my TShoot Exam on 5th January, 2012 with 1000/1000, Allhamdulilah.
“Networktut” website and my brother Sohaib Fouzi helped me to prepare this exam, thanks for both of you.
All TTs are still valid and same as mentioned under “networktut”. I got multiple choices and 13 TTs. Except EIGRP AS all TTs came. In All TTS Client1 will have valid IPs (except 4 TTs of 169.x.x.x).
I did my complete exam using only “ipconfig”, “ping” and “show run” commands and never felt to use any other command. One thing is very important that you should have complete understandings of TTs other wise you will not able to understand 2 or 3 TTs because Cisco made very minor changes in mulitple choices or in configuration. The IP scheme between R4, DSW1 and DSW2 is 10.1.4.x.
When i entered in LAB, before starting my exam i wrote the below lines on the provided sheet and then it became very easy to solve the TTs. To solve the TTs i followed the following scheme and order: (remember to use “ipconfig” and “ping” always in Client1 for all TTs)

->> If it is 169.x.x.x there are 4-TTs
1.ASW1 – port security (show-run ASW1 if 1/0/1 and 1/0/2 are in Vlan10, apply sh int for both)
2.ASW1 – access vlan 10 (show-run and check ASW1 if 1/0/1 and 1/0/2 are in Vlan1, if they are… stop!)
3.ASW1 – switch-to-switch (show-run ASW1)
4.R4 – DHCP excluded (show-run R4)
——————————————————————-

->> If client got IP address then 2 options:

-First, if client1 can ping 10.1.1.1 not to server 209.65.200.241 (3TT) ALL IN R1
1.R1 – NAT (10.2.0.0) (show-run R1)(sh ip BGP summary)
2.R1 – BGP (56-65) (show-run R1)(sh ip BGP summary)
3.R1 – ACL (show-run R1)(sh ip BGP summary)

-Second , Client can’t ping 10.1.1.1 but it can ping to 10.1.1.2) then: (1TT)
4-R1 – OSPF authentication (show-run R1 + R2)

-Thirdly, if client1 cannot ping 10.1.1.1, then (4 TTs)
1. DSW1(ASW1) – vlan access map(vlan acl port) *** this one cannot ping even gateway (Check vlan-filter command, which contain vlan access-map, this contain access-list no., now check access-list no. It can drop the packet for PC conntected to ASW1.)
2. R4 – Route redistribution: (show-run R4)(EIGRP->OSPF is created and EIGRP-TO-OSPF is used)
3. R4 – EIGRP Passive Interface: passive interface (show-run R4)(sh IP protocols )
4-R4-EIGRP AS: AS number of EIGRP is different is used To verify – show IP protocols.
——————————————————————-

->> Finally, there are 2 distinct TTs,
- HSRP on DSW1: Check DSW1 Use track 10 instead of track 1 (show run) and this is the only question you will see tracking.
- OSPF IPv6 on R2: On serial interface use area 0, not area 12 (show run), you will recognize this TT by reading ticket because it is the only TT which says about IPv6.

Note: The above scheme i copied from one comment under “networktut”, i dont remember the name. Sory to mention under my comments but it was just to help others. Please feel free for any query, my email address belal_fouzi@yahoo.com

These all YouTube gaming video lessons are actually in pleasant quality, I watched out all these along by means of my mates.

I got this website from my pal who told me concerning this site and at the moment this time I am visiting this web page and reading very informative articles or reviews here.
