Parameters
backup-nexthop ipv6-address: Specifies an IPv6 backup next hop.
Usage guidelines
This command sets a backup link in the routing policy for FRR.
Using the routing policy, a routing protocol can designate a backup link for specific routes to implement
FRR. When the primary link fails, FRR immediately directs packets to the backup link to minimize
interruption time.
Examples
# Configure node 10 of routing policy policy1 to set the backup next hop 1::1/64 for the route destined
for 100::1/64.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc index 10 permit 100::1 64
[Sysname] route-policy policy1 permit node 10
[Sysname-route-policy-policy1-10] if-match ipv6 address prefix-list abc
[Sysname-route-policy-policy1-10] apply ipv6 fast-reroute backup-nexthop 1::1
apply ipv6 next-hop
Use apply ipv6 next-hop to set a next hop for IPv6 routes.
Use undo apply ipv6 next-hop to restore the default.
Syntax
apply ipv6 next-hop ipv6-address
undo apply ipv6 next-hop
Default
No next hop is set for IPv6 routes.
