Ticket 12 – IPv6 OSPF

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
 router-id 2.2.2.2
!
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) on the serial interface of R2, enter the command ipv6 ospf 6 area 0 (notice that it is “area 0″, not “area 12″)
