Default command level
2: System level
Parameters
backup-interface interface-type interface-number: Specifies a backup outbound interface by its type and
number. If the specified backup outbound interface is a non-P2P interface (including NBMA and
broadcast interfaces, such as an Ethernet interface, virtual template interface or VLAN interface), you
must also specify a backup next hop.
ip-address: Backup next hop address.
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 output interface GigabitEthernet 2/1/1
and backup next hop 193.1.1.8 for the route destined to 100.1.1.0/24.
<Sysname> system-view
[Sysname] ip ip-prefix abc index 10 permit 100.1.1.0 24
[Sysname] route-policy policy1 permit node 10
[Sysname-route-policy] if-match ip-prefix abc
[Sysname-route-policy] apply fast-reroute backup-interface gigabitethernet 2/1/1
backup-nexthop 193.1.1.8
apply ip-address next-hop
Use apply ip-address next-hop to set a next hop for IPv4 routing information.
Use undo apply ip-address next-hop to remove the clause configuration.
Syntax
apply ip-address next-hop ip-address
undo apply ip-address next-hop
Default
No next hop is set for IPv4 routing information.
