Interface
The output information shows that Switch A communicates with Switch B through VLAN-interface 10.
The link over VLAN-interface 10 fails.
# Display routes to 2001:4::0/64 on Switch A.

The output shows that Switch A communicates with Switch B through VLAN-interface 11.

OSPFv3 FRR configuration example

Network requirements
As shown in
Configure OSPFv3 FRR so that when Link A fails, traffic is immediately switched to Link B.

Configuration procedure
1. Configure IPv6 addresses and subnet masks for interfaces on the switches. (Details not
shown.)
2. Configure OSPFv3 on the switches to ensure that Switch A, Switch B, and Switch C can
communicate with each other at the network layer. (Details not shown.)
3. Configure OSPFv3 FRR to automatically calculate the backup next hop:
: FE80::20F:FF:FE00:1200
: Vlan10
: FE80::BAAF:67FF:FE27:DCD0
: Vlan11
Figure 104, Switch A, Switch B, and Switch C reside in the same OSPFv3 domain.
