Static route FRR configuration example
Network requirements
Router S, Router A, and Router D are interconnected through static routes, as illustrated in Figure 3 .
Configure static route FRR so that when the link between Router S and Router D fails, traffic can be
switched to Link B immediately.
Figure 3 Network diagram
Configuration procedure
1. Configure IP addresses for the interfaces on each router and configure static routes:
Follow
Figure 3 to configure the IP address and subnet mask of each interface on the routers.
(Details not shown)
Configure static routes on Router S, Router A, and Router D so that Router S can reach Loopback
0 on Router D and Router D can reach Loopback 0 on Router S.
# Configure a static route on Router S.
system-view
[RouterS] ip route-static 4.4.4.4 32 GigabitEthernet 3/1/2 13.13.13.2
[RouterS] ip route-static 4.4.4.4 32 GigabitEthernet 3/1/2 12.12.12.2 preference 65
# Configure a static route on Router D.
system-view
[RouterD] ip route-static 1.1.1.1 32 GigabitEthernet 3/1/2 13.13.13.1
[RouterD] ip route-static 1.1.1.1 32 GigabitEthernet 3/1/2 24.24.24.2 preference 65
# Configure a static route on Router A.
system-view
[RouterA] ip route-static 4.4.4.4 32 GigabitEthernet 3/1/2 24.24.24.4
[RouterA] ip route-static 1.1.1.1 32 GigabitEthernet 3/1/1 12.12.12.1
2. Configure static route FRR:
# Configure Router S.
[RouterS] bfd echo-source-ip 1.1.1.1
[RouterS] ip ip-prefix abc index 10 permit 4.4.4.4 32
[RouterS] route-policy frr permit node 10
[RouterS-route-policy] if-match ip-prefix abc
[RouterS-route-policy] apply fast-reroute backup-interface GigabitEthernet 3/1/1
backup-nexthop 12.12.12.2
[RouterS-route-policy] quit
[RouterS] ip route-static fast-reroute route-policy frr
# Configure Router D.
