Configuration guidelines

Do not use the fast-reroute lfa command together with the vlink-peer command.

Configuration procedure

Configuring OSPFv3 FRR to calculate a backup next hop using the LFA algorithm
Step
1. Enter system view.
2. Enter interface view.
3. (Optional.) Disable LFA on
an interface.
4. Return to system view.
5. Enter OSPFv3 view.
6. Enable OSPFv3 FRR to
calculate a backup next hop
by using the LFA algorithm.
Configuring OSPFv3 FRR to specify a backup next hop using a routing policy
Before you perform this task, use the apply ipv6 fast-reroute backup-interface command to
specify a backup next hop in the routing policy to be used. For more information about the apply
ipv6 fast-reroute backup-interface command and routing policy configuration, see
routing policies."
To configure OSPFv3 FRR to specify a backup next hop using a routing policy:
Step
1. Enter system view.
2. Enter interface view.
3. (Optional.) Disable LFA on
an interface.
4. Return to system view.
5. Enter OSPFv3 view.
6. Enable OSPFv3 FRR to
specify a backup next hop by
using a routing policy.
Configuring BFD for OSPFv3 FRR
By default, OSPFv3 FRR does not use BFD to detect primary link failures. To speed up OSPFv3
convergence, enable BFD for OSPFv3 FRR to detect primary link failures.
To configure BFD control packet mode for OSPFv3 FRR:
