Ticket 12 – IPv6 OSPF

April 25th, 2018 in TSHOOT v2 Go to comments

DSW1 & R4 can’t ping R2’s loopback interface or s0/0/0.12 IPv6 address.
R2 is not an OSPFv3 neighbor on R3
Situation: ipv6 ospf was not enabled on R2’s serial interface connecting to R3. (use ipv6 Layer 3)

Configuration of R2
ipv6 router ospf 6
interface s0/0/0.23
 ipv6 address 2026::1:1/122

Configuration of R3
 ipv6 router ospf 6
interface s0/0/0.23
 ipv6 address 2026::1:2/122
 ipv6 ospf 6 area 0


In interface configuration mode of s0/0/0.23 on R2:
ipv6 ospf 6 area 12

Ans1) R2
Ans2) IPv6 OSPF Routing
Ans3) Under the interface Serial 0/0/0.23 configuration enter the ‘ipv6 ospf 6 area 0’ command. (notice that it is “area 0”, not “area 12”)

Bug in this ticket: There is a bug in this ticket in the exam that under interface s0/0/0.23 the IPv6 address is /123, not /122 but this is not the fault of this ticket so be careful. Also there is no option about “change /123 to /122”.

    How about this strategy

    If client ip is 169.x.x.x

    1) Check for DCHP exclude on R4 by “sh run”. (DHCP TICKET)
    2) Check for err-disable on ASW1 by “sh run”,”sh int f1/0/1″. (PORT SECURITY)
    3) Check for vlan-id/non on ASW1 by “sh run”. If no vlan or invalid vlan (1) define under interfaces then (VLAN-ACCESS)
    4) Check for “20,200” on ASW1 by “sh int trunk”. (Switch-to-Switch)

    If client ip

    Case 1-> Can ping but can’t ping from client
    Check OSPF AUth. on R1 by “sh run” and compare the configuration with R2 “sh run” command. (OSPF Authenticaiton)

    Case 2-> Can ping
    on R1 if “sh ip bgp summary” = up/up (NAT)
    on R1 if “sh ip bgp summary” = no output (BGP)
    on R1 if “sh ip bgp summary” = active (ACL / IPv4 Security)

    Case 3-> Can not ping
    First check if its the case 1 problem, if already solved or its not OSPF ticket then proceed….

    on DSW1 “sh run”, “sh access-list” You will see the action drop in “sh run” or “deny” statement (Vlan/port MAP)
    on R4 “sh run” and look for ‘Eigrp Passive’ under Eigrp (EIGRP Passive interface)
    on R4 “sh run” and look for redistribution “OSPF_TO_EIGRP”, correct is “OSPF->EIGRP” (Route Redistribution)

    *HSRP will be mentioned in the Ticket and can be confirmed by going DSW1 “sh run” and look for “track 1 statement”. (HSRP)

    *IPv6 will be mentioned in the Ticket too. (IPV6 OSPF)

    If stuck any where. try this:

    1) Ping from every device to If can’t ping, then check for “passive Interface” on R4.
    2) Check DSW1 for HSRP by “sh run” (HSRP)
    3) Check EIGRP AS on R4 and compare with DSW1 and DSW2 by “sh run”. If AS is 1. then (EIGRP AS). Don’t know whether you get 169.x or IP on client. Can someone guide me here.

    I will appreciate if anyone correct my method if I was wrong in any point. Also in “EIGRP AS” ticket, what will be the clients IP?

    Hi All,

    Do anybody have packet tracer file for these 3 topologies to practice . Please share the same .

    Hi Guys,

    Cleared TSHOOT today so it is still valid. Got confused for IPV6 ospf LAB :( The problem symptom was – R1 ipv6 loopback not reachale from DSW2. Anyways it was my mistake. Be prepared for IPV6. Also objective questions statements were somewhat different.

    is Trouble shoot is Multiple choice question like CCNP route and Switch or Purely Lab. we need to do the configuration changes in exam..

    Hello Everyone for all updates and information about T-shoot,

    Do we need to do the configuration changes in real exam?

    Can someone suggest one of these CCNP lab kits http://www.certificationkits.com/ccnp-certification-kits/ so I can do the labs that are on this site? Or do I really need to review every lab on this site and try to figure out a topology to cover it all?

    Passed on 17th, thanks to Almighty Allah! Got 1000/1000.

    1_ Memorize all tickets.
    2_ Understand Sami’s algorithm.

    Thats all you really need to do for the tickets section.
    After understanding Sami’s algo, you can match it with Sara’s or Khattak’s strategy.

    Best thing to do is to jot the tickets down on the sheet you get at the exam center before starting the tickets section. I even wrote Sami’s algorithm.
    No IP helper adress or wrong EIGRP AS number. All tickets are valid.

    Good luck y’all!

    All tickets still valid, just passed the test with 1000. On the ipv6, the ticket is a little messed up. The “ipv6 ospf 6 area 12” (wrong area, needs to be 12) is under loopback 6 on R2 when you do “sh run”, but when you choose the answers, it says that you need to correct the “ipv6 ospf 6 area 12” under s0/0/0.23 and loopback 6 is not an option. Kind of gets you if you actually are troubleshooting rather then memorizing answers.

    Thanks a lot Network Tut and all the guys posting updates here. It helped me sail through the Tshoot on 4th Oct. So, dumps are still valid. Would like to mention one thing, if you’ve a slightest of doubt in a ticket, keep it for the end, just abort it and move on to others first. There came a situation wherein got confused b/w ospf authentication ticket & ospf ipv6 one. Don’t know why but somehow it did not strike me to check ‘ipv6 ospf neighbourship’ b/w R2 & R3 and finally after some confused thinking I marked answers of ‘ospf authentication ticket’. Came to realise in the authentication ticket, the blunder I did. Still, comfortably cleared the exam. Thanks :)

    Hi Guys,

    It took Just 30 Minutes to get 1000 , Thanks a lot network tut.

    for My exam there were no glitches no bugs everything was perfect .
    I didn’t get any Eigrp passive interface and the only time when i wasn’t able to ping it was vlan access map and i removed vlan filter so that seems to be correct answer.

    I kept BGP as reference and as sinole mentioned wrote down all the tickets in advance.

    All the best guys..

    Hi All, Just someone to clear something for me. How will I know if a specific question is related to ASW1, DSW1, R4, R2 or even R1? Or how will I know its Allowed Vlan ticket, Port Security ticket, NAT ACL tickets e.t.c. Thank you all.

    Hello All, Will “Show run” be enough to figure out all issues in the exam? Yes I mean for all 13Tickets. You advise is appreciatede. I’m writing this Friday. Thank you all in advance.

    I don’t understand, are these trouble tickets multiple choice, or do we actually make the config changes on the CLI???

    thank you everyone

    I have just passed my TSHOOT exam (first attempt). My strategy was that I downloaded these GNS3 scenarios and then resolved all issues, came back to verify work for accuracy. I only used the show and ping commands. You can go through a ticket, see if you are able to resolve it and then come back. Some of the configurations can help you to compare.
    My first step was always to do the ipcondig, if there is no IP address then use the L2 diagram. Start off on AW1 then DSW, etc. If the IP address was present, I would ping nearest first if I get a response, I go to the furthest point (R1 in this case). If R1 can ping the webserver, then I pinged from DSW1 to make sure the client is the only that cant ping (this is normally caused by filters). Anyways, in short, I used the follow the path method. Then started from layer 1 up.

    @buddyoldpal, the TT are NOT multiple choice, you do get a handful of multiple choice questions in the beginning of the exam. Cisco does provide a sample exam that you can use so that you can familiarize yourself with the test format

    As you know already, we will have to answer3 questions in a TT,
    the important point to remember here is that Q2 answers depend on which device you selected in Q1, And Q3 answer options again depend on which technology you select in Q2. So be cautious and select correct answer. you better follow troubleshooting techniques before deciding.
    Vlan filter TT BUG in cisco exam is not yet corrected, we still need to select ASW1 then only you will be prompted to select the correct answer (remove vlan filter test1″)
    EIGRP Wrong AS TT also seems to have a bug, I saw ROUTER EIGRP 10 properly configured in R4, when I see show ip eigrp neighbor, there are no neighbors listed. and surprisingly it says EIGRP AS 1 instead of AS 10.
    in solutions we have two valid options 1.)change EIGRP AS number from 1 to 10 to match with DSW1 and DSW2 2.) change network statement network to, As per show eigrp neighbor command output I considered 1.as solution. But I think I lost marks in this question only.
    I am sure that this is not EIGRP passive case, coz I see commands in DSW1 passive interface default and NO passive int fa1/0/1(connecting from DSW1 to R4). beyond this I am not sure if i missed any point in this TT.

    I have downloaded the IPv4 layer 3 technology from this link http://dl.dropbox.com/u/2749921/GNS_Tshoot.tar.gz but it has only client1 and that is a switch so how would i know what IP address it has and how would i add another client2 to it to ping it from client1. Do i need to add workstations manually ? Thanks in advance guys…

    Is the ospf v6 question “an ipv6 topic” or “ospfv3” i see people answering different ways as far as the question two of the ticket.

    May 24th, 2014

    Hey guys cleared tshoot exam today 5/24/2014 **All tickets still valid** There are strategies out there, this what I used.

    1- Find 4 tickets for R1. ***OBS*** number in parentheses represent ticket’s order on Networktut.com
    -> If can ping the tickets will be:
    – Nat ACL(4),BGP Neighbor (3) R1 ACL (5)
    -> if can’t ping but can ping ticket will be:
    – OSPF Authentication (1)

    2- find the 2 tickets for HSRP TRACK (2) DSW1 and IPV6 OSPF (12) R2

    3- find 4 tickets 3 for ASW1 and 1 for R4
    -> If client get ip 169.x.x.x or no IP address, tickets will be:
    -Switchport vlan 10 (8)
    -Port security (7) int 1/0/1 shutdown in **error disable** .
    -Switchport trunk (9) All in ASW1
    The other ticket will be in R4
    -DHCP Range (13)

    4- find one ticket where client get ip 10.x.x.x but can’t ping default gateway, ticket willl be:
    -Vlan filter (6) it will be DSW1 or ASW1 check for option port/acl

    5- 2 tickets where client get 10.x.x.x these two tickets will be:
    -OSPF to EIGRP (11) R4
    -EIGRP Passive Interface (14) R4

    I would advice to become premium member to interact with these tickets.

    Good lucky guys!!

    I took TShoot exams yesterday:

    Got 1000 scores
    Got 2 Multiple questions, with slightly changes in choices but answers posted here hold still.
    Got 1 drag and drop
    Got 13 TTs
    TTs here are all valid.

    Just study CCNP official cert guide to gain confidence and to back you up in case of trouble.

    Thanks to this site and to khatakk for strategy.
    I am now CCNP!

    Dear all,

    Who can tell me that why the ans is ipv6 ospf 6 area 0 but not ipv6 ospf 1 area 0 ?

    @michael: The OSPF process IDon R2 in this case is “6”, not “1”:
    ipv6 router ospf 6
