(Method 2.) Enable OSPF FRR to designate a backup next hop by using a routing policy:
# Configure Switch S.
<SwitchS> system-view
[SwitchS] bfd echo-source-ip 1.1.1.1
[SwitchS] ip ip-prefix abc index 10 permit 4.4.4.4 32
[SwitchS] route-policy frr permit node 10
[SwitchS-route-policy] if-match ip-prefix abc
[SwitchS-route-policy] apply fast-reroute backup-interface vlan-interface 100
backup-nexthop 12.12.12.2
[SwitchS-route-policy] quit
[SwitchS] ospf 1
[SwitchS-ospf-1] fast-reroute route-policy frr
[SwitchS-ospf-1] quit
# Configure Switch D.
<SwitchD> system-view
[SwitchD] bfd echo-source-ip 4.4.4.4
[SwitchD] ip ip-prefix abc index 10 permit 1.1.1.1 32
[SwitchD] route-policy frr permit node 10
[SwitchD-route-policy] if-match ip-prefix abc
[SwitchD-route-policy] apply fast-reroute backup-interface vlan-interface 101
backup-nexthop 24.24.24.2
[SwitchD-route-policy] quit
[SwitchD] ospf 1
[SwitchD-ospf-1] fast-reroute route-policy frr
[SwitchD-ospf-1] quit
4. Verify the configuration:
