Ticket 12 – IPv6 OSPF

April 25th, 2018 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”.

    For this scenario R3 is culprit along with the misconfiguration on RIP Redistribution

    Guys, very usefull website : https :// www. networklab .fr / tshoot-ipv6-ticket-1 /
    (need to translate it)

    Commands to best TSHOOT :
    1. ping > Traceroute > show ipv6 route >show ipv6 protocols summary > show ipv6 ospf neighbor.

    Some CMDs are maybe not allowed in the exam.

    Based on specific Router ( From Flow chart ) ping i can go to that particular router and perform ping and sh commands or should i ping and sh commands in all routers and SW needed ?
    Please help me out.
