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”.

    OSPFv3 uses LL addresses to form neighbor adjacency so having a different subnet mask is not an issue, so don’t let that confuse you.

    Had this on the exam, I got it wrong.

    It’s important to note, all the devices can ping R1 but R1 can’t ping out. That’s the give away for this ticket. It’s because R2 is advertising it’s connected prefix (the R1 address), so everyone can see a path to it. But because R1 is not receiving any ipv6 routes, it only know how to ping R2.
