Static route FRR configuration example
Network requirements
Switch S, Switch A, and Switch D are interconnected through static routes, as illustrated in Figure 3 .
Configure static route FRR so that when the link between Switch S and Switch D fails, traffic can be
switched to Link B immediately.

Configuration procedure
1. Configure IP addresses for the interfaces on each switch and configure static routes.
Follow Figure 3 to configure the IP address and subnet mask of each interface on the switches. (Details
not shown)
Configure static routes on Switch S, Switch A, and Switch D so that Switch S can reach Loopback 0 on
Switch D and Switch D can reach Loopback 0 on Switch S.
# Configure a static route on Switch S.
system-view
[SwitchS] ip route-static 4.4.4.4 32 vlan-interface 200 13.13.13.2
[SwitchS] ip route-static 4.4.4.4 32 vlan-interface 100 12.12.12.2 preference 65
# Configure a static route on Switch D.
system-view
[SwitchD] ip route-static 1.1.1.1 32 vlan-interface 200 13.13.13.1
[SwitchD] ip route-static 1.1.1.1 32 vlan-interface 101 24.24.24.2 preference 65
# Configure a static route on Switch A.
system-view
[SwitchA] ip route-static 4.4.4.4 32 vlan-interface 101 24.24.24.4
[SwitchA] ip route-static 1.1.1.1 32 vlan-interface 100 12.12.12.1
2. Configure static route FRR.
# Configure Switch S.
