Configuration procedure

Configuring IPv6 IS-IS FRR to calculate a backup next hop through LFA calculation
Step
1. Enter system view.
2. Enter interface view.
3. (Optional.)
calculation on the interface.
4. Return to system view.
5. Enter IS-IS IPv6 unicast
address family view.
6. Enable IPv6 IS-IS FRR to
calculate a backup next
hop
calculation.
Configuring IPv6 IS-IS FRR using a routing policy
You can use the apply ipv6 fast-reroute backup-interface command to specify a backup next hop
in a routing policy for routes matching specific criteria. You can also perform this task to reference the
routing policy for IPv6 IS-IS FRR. For more information about the apply ipv6 fast-reroute
backup-interface command and routing policy configurations, see

4. Return to system view.
5. Enter IS-IS IPv6 unicast
address family view.
6. Enable IPv6 IS-IS FRR
using a routing policy.
Enabling BFD for IPv6 IS-IS FRR
By default, IPv6 IS-IS FRR does not use BFD to detect primary link failures. To speed up IPv6 IS-IS
convergence, enable BFD for IPv6 IS-IS FRR to detect primary link failures.
To enable BFD control packet mode for IPv6 IS-IS FRR:
