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”)

    Hi Guys,,
    I Cleared CCNP TSHOOT on 30th Sep 2016 with 1000 Marks. I am going to my share experience of recent completion of exam details with new Packet tracer labs and Multiple choice explanation on You tube channel. If any one plan to take exam in upcoming days, I hope will helpful for you to score 1000 Marks. Please subscribe to my channel if you like it. Right now i had posted previous videos in tamil, But will post Labs in English with fixing Voice issue in video faced by user in previous videos. Your Suggestion welcome on Channel…

    This is my TSHOOT IPV6 using show ip route method, let me know if it all seems good.

    ipv6 ospf 6 area 0 – R2
    R1 and R2 are not ospf6 neighbors with each other, after runing sh ipv6 ospf nei. R2 has no
    interfaces in area 0. As a result, R1 will have no OI routes for area 0 (2026::1) nor 2026::34 (area 34) that connects to area 0. But DSW will have routes for area 0 (2026::1) and 2026::34 (area 34), but not area 12 (2026::12)

    IPV6 Tunnel problem – R3
    R4 has no ospf6 neighbors because the tunnel mode on R3 is not compatible. As a result
    R3 will have no redistributed routes (OE2) from the DSW Ripzone (2026::3), (2026::102), and DSW will not have any routes to the OSPF6 network area 0 (2026::1), 2026::34 (area 34), or area 12 (2026::12)

    Redistribute Ripzone into OSPF -R4
    No missing ospf neighbors but R3 has no redistributed routes (OE2) from the DSW Ripzone (2026::3), (2026::102). DSW1 will however have routes to ALL OSPF6 area 0 (2026::1), 2026::34 (area 34) and area 12 (2026::12)

    @Network Tut: On which serial interface “ipv6 ospf 6 area 0” should be enter? One of my friend told me that both option came in his exam? Waiting for response.

    @Peter – R2 – interface s0/0/0.23 – ipv6 ospf 6 area 0

    I cleared my 300-135 exam with the use of Grades4sure dumps. I got all same questions in my exam that I prepared from Grades4sure test engine software. I recommend http://www.grades4sure.com/300-135-exam-questions.html to you if you want to clear your exam in first attempt.

    The materials are very accurate. Few incorrect answers. But I do not expect a full score, anyway. 89% is enough for me. I just passed my exam 9 hours ago. http://www.testmayor.com/300-135-test.html dumps are trustful. I recommend it to all who want to pass their exam in the first attempt. Practice your exam with this dumps and Test engine you will 100% pass your exam.

    On ticket 12 I see that R4 cannot ping R3 as well aas R2 in IPV6. What is the best way to determine that issue is in R2 . As R4-R3 also have network issue . Or is it a bug ?
    Please help . Writing exam next week

  14. ticket 12
    May 21st, 2017

    Anyone plz let me know that in ticket no 12 .even without identifying the fault we can still ping the destination address .can anyone plz explain me about it.thanks

    Hi everyone,
    Is there a new ticket on IPv6 with the issue on R1? If there is, could you please sure your answer with us and let us know what the correct answer is?


  16. Ziuka

    Client 1 can still ping in this ticket because both client 1 and webserver have ipv4 address, and there’s no issue with ipv4 in ipv6 tickets.

    IPv6 Ping Plan
    R1#ping ipv6 2026::1:2 (Can you reach the R3 Area 0 interface)
    No –> IPv6 OSPF
    Yes R1# ping ipv6 2026::34:2 (Can you reach the R4 GRE tunnel interface)
    No –> IPv6 GRE Tunnel
    Yes –> IPv6 RIPng OSPFv3

    You can also determine the answer using sh ipv6 ospf nei on DSW1.
    No routes for ospf area 12 (2026::12) –> R2: IPv6 OSPF Routing
    No routes for ospf areas 12, 0, or 34 –> R3: IPv6 GRE Tunnel
    All ospf routes for areas 12, 0, & 34 –> R4: IPv6 RIPng OSPFv3 redistribution

    don’t type command ”ping” in exam doesn’t work
    use command ” sh ipv6 ospf” neigh from R3
    r3 ( 1 neighbor — inter face tunnel ) —–> problem R2
    r3 ( 1 neighbor — inter face serial ) —–> problem R3
    r3 ( 2 neighbor — 2 inter face tunnel +serial ) —–> problem R4

    This wasn’t in my exam today or was on another router. I passed.

  24. IPV6
    November 1st, 2017

    I passed my Tshoot exam 903!!!

    BGP Sim is good
    MCQ are good
    Now I did notice that there was a question were the ipv6 subnet mask was a /123 instead of being /122, so if you are pinging from R1, I would start by pinging R2 IPs on both sides of the router to determine if this may be one of your problems. Make sure to check the S0/0/0.23 interface on R2 and compare the ipv6 subnet mask the P2P on R3.

    @ipv6 ,

    hi! do you remenber the answers then?

    should it be something like…

    Ans1) R2
    Ans2) IPv6 OSPF Routing
    Ans3) Under the interface Serial 0/0/0.23 change /123 mask ….?

    Hi Guys, I have my exam tomorrow, could you please tell how to identify ipv6 question? Will it say in the question that it is ipv6 or something ? Please help asap….

    I do not understand something on this… first for sure R2 missing ‘ipv6 ospf 6 area 0’ is true, BUT… I got confused when first my eyes went on R3 and his connectivity to R4…

    On R3: isn’t this router missing also ‘ipv6 ospf 6 area 34’… under S0/0/0.34 link to R4? this exists only under the tunnel interface

    On R4: ‘ipv6 ospf 6 area 34’ is both configured in the tunnel interface AND on s0/0/0 (link to R3)

    …therefore while doing this simulation here in tut, I selected
    2)IPv6 Routing
    3)”Under the interface Serial0/0/0.34 configuration enter the ‘ipv6 ospf 6 area 34’ command” …
    And I could not see why I got “Incorrect! Please try again!”. As I said R4 does not miss this command (as R2, but ALSO R3 does). Anyone explaining this would be appreciated.

    @networktut – Can you confirm if we need to do “ping 2026::1:2” or “ping ipv6 2026::1:2” on the real exam. i’m a premium member and would like to confirm this – Thanks

    dear fd77 i
    pv6 ospf 6 area 34 command applied only tunel interface on both router (R3&R4) , no need add

    no need add to interface Serial0/0/0.34 point-to-point

    So, correct answer is ,

    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”)

    1. sho ipv6 route on DSW1
    2. sho ipv6 inter br on R2 – FEC0::2:2 (loopback2 address of R2)
    3. interface Serial0/0/0.23 point-to-point
    ipv6 ospf 6 area 0
    4. After that you can check again sho ipv6 route on DSW1
    now routing table will differently . And you can see FEC0::2:2 (loopback2 address of R2) now on DSW1 routing table

    Yes there is a IPv6 L3 topology given in the TT.

    Why in ticket 12 after you correct the issue and run the sh ipv6 route command you are getting a NSSA no summary route advertised? IPv4 has the NSSA configured but its not for IPV6, is that because you are running the tunnel over ipv4?

    I think we the key command in this ticket would ‘show ipv6 ospf nei’. We may run this command from R1 to R4 to make sure whether the neighborship is broken for ipv6 between each of these routers; we should know this is an IPV6 ticket because it should mention IPv6 statement/address in the questions.

    Thank you.

    I practice this ticket 12 from packet tracer, I dun know why I can’t ping ipv6 address to DSW1 and DSW2 that is directly connected each other. Please suggest me,this is packet tracer issue or something else.

    Thanks Networktut, all questions got from the exam which are published here. (Premium membership)

    guys follow all the lab questions and MCQs. don’t memorise every thing, try to catch base of the question.

    in IPv6 lab questions kindly follow @someone method(the comment published above somewhere). Its works well real exam and networktut mentioned lab questions.

    @Someone, thanks your method.
    for those who cant find the @someone method. I copied it for you below.

    don’t type command ”ping” in exam doesn’t work
    use command ” sh ipv6 ospf” neigh from R3
    r3 ( 1 neighbor — inter face tunnel ) —–> problem R2
    r3 ( 1 neighbor — inter face serial ) —–> problem R3
    r3 ( 2 neighbor — 2 inter face tunnel +serial ) —–> problem R4

    All, this question got me on recent exame. R2R3 weren’t ospfv3(IPV6) neighbors.
    I found two issues:
    1. ipv6 ospf 6 area 0 was missing on R2 s0/0/0.23 interface
    2. subnet mask for on this interface was /123 . Where R3 had /122.
    Both of those issue to my best knowledge will keep OSPFv3 neighbors down. Which one is the best answer ?

    Packet tracer an interface on R2 was missing ipv6 ospf 6 area 0 command. Loopback 2 now pingable from R4. <4 mins.

  44. Freeman
    October 10th, 2018

    And what about DSW 1 and 2.
    They can not ping R2 after ipv6 ospf 6 area 0
    What is going on with them?
