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
 router-id 3.3.3.3
!
interface s0/0/0.23
 ipv6 address 2026::1:2/122
 ipv6 ospf 6 area 0

Answer:

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”.

    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.

    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??

    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.

    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/

    @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.

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

  17. Naveed

    @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.

    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?
