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
To configure IPv6 IS-IS FRR using a routing policy:
Step
1. Enter system view.
2. Enter interface view.
3. (Optional.) Disable LFA
calculation on the interface.
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:
Step
1. Enter system view.
2. Enter interface view.
3. Enable BFD control packet
mode for IPv6 IS-IS FRR.
To enable BFD echo packet mode for IPv6 IS-IS FRR:
Step
1. Enter system view.
2. Configure the source IPv6
address of BFD echo packets.
