Hey guys,
I have been trying to figure out how to do this IPV6 OSPv3 lab here today. I know that I am missing something. I have included a diagram for your review as to what the network looks like. I have defined router ID's on all the routers.
R1 -> 1.1.1.1
R2 -> 2.2.2.2
R3 -> 3.3.3.3
R4 -> 4.4.4.4
Each router has ipv6 unicast-routing enabled, and each interface has an IPv6 address assigned to it (a link local address FE80..). In addition, I have enabled OSPFv3 on the interfaces between R1 to R2, R2 to R3, and R3 to R4. I know where the issue lies, R4 is connected to R3, which is not connected to area 0. This is where it comes into play needing a virtual link to be created. Here is what I tried to do.
On R4.
ipv6 router ospf 1
area 12 virtual-link 2.2.2.2
On R2
ipv6 router ospf 1
area 12 virtual-link 4.4.4.4
I used the router id's which are still expressed in a 32-bit format. Each router has an adjacency to the other routers.
R1#show ipv6 ospf neighbor
Neighbor ID Pri State Dead Time Interface ID Interface
2.2.2.2 1 FULL/ - 00:00:32 4 Serial0/0
R2#show ipv6 ospf neighbor
Neighbor ID Pri State Dead Time Interface ID Interface
1.1.1.1 1 FULL/ - 00:00:30 4 Serial0/0
3.3.3.3 1 FULL/ - 00:00:34 4 Serial0/1
R3#show ipv6 ospf neighbor
Neighbor ID Pri State Dead Time Interface ID Interface
2.2.2.2 1 FULL/ - 00:00:32 5 Serial0/0
4.4.4.4 1 FULL/ - 00:00:34 4 Serial0/1
R4#show ipv6 ospf ne
Neighbor ID Pri State Dead Time Interface ID Interface
3.3.3.3 1 FULL/ - 00:00:37 5 Serial0/0
What I can't figure out is the fact that my virtual-link never comes up.
R4#show ipv6 ospf virtual-links
Virtual Link OSPFv3_VL0 to router 2.2.2.2 is down
Interface ID 13, IPv6 address ::
Run as demand circuit
DoNotAge LSA allowed.
Transit area 12, Cost of using 65535
Transmit Delay is 1 sec, State DOWN,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
R2#show ipv6 ospf virtual-links
Virtual Link OSPFv3_VL0 to router 4.4.4.4 is down
Interface ID 12, IPv6 address ::
Run as demand circuit
DoNotAge LSA allowed.
Transit area 12, Cost of using 65535
Transmit Delay is 1 sec, State DOWN,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
My question is, what am I forgetting. Can they not reach each other because R4 doesn't know how to get to 2.2.2.2 and R2 doesn't know how to get to 4.4.4.4?
