(Method 2.) Configure static route FRR to automatically select a backup next hop:
# Configure static routes on Switch A, and enable static route FRR.
<SwitchA> system-view
[SwitchA] bfd echo-source-ip 4.4.4.4
[SwitchA] ip route-static 4.4.4.4 32 vlan-interface 200 13.13.13.2
[SwitchA] ip route-static 4.4.4.4 32 vlan-interface 100 12.12.12.2 preference 70
[SwitchA] ip route-static fast-reroute auto
# Configure static routes on Switch B, and enable static route FRR.
<SwitchB> system-view
[SwitchB] bfd echo-source-ip 1.1.1.1
[SwitchB] ip route-static 1.1.1.1 32 vlan-interface 200 13.13.13.1

[SwitchB] ip route-static fast-reroute auto
3.
Configure static routes on Switch C.
<SwitchC> system-view
[SwitchC] ip route-static 4.4.4.4 32 vlan-interface 101 24.24.24.4
[SwitchC] ip route-static 1.1.1.1 32 vlan-interface 100 12.12.12.1
