Configure static route in such a way that the next-hop interfaces point to each other. ● Configure BFD for a specific IPv4 static route using the following command in CONFIGURATION mode: ip route [vrf vrf-name] dest-ip-prefix mask {next-hop [interface interface-type] [route-preference]} bfd ● Configure BFD for a specific IPv6 static route using the following command in CONFIGURATION mode: ipv6 route [vrf vrf-name] dest-ipv6-prefix mask {next-hop [interface interface-type] [route-preference]} bfd The following is an example configuration for enabling BFD for specific static routes on the default VRF: OS10(config)#ip route 10.2.2.0/24 10.1.1.1 bfd The following example enables BFD for specific static routes on a nondefault VRF: OS10(config)#ip route vrf LAN2 10.2.2.0/24 10.1.1.1 bfd The following example enables BFD for specific IPv6 static routes on the default VRF: OS10(config)# ipv6 route 2111:dddd:0eee::22/128 2001:db86:0fff::2 bfd The following example enables BFD for specific IPv6 static routes on a nondefault VRF: OS10(config)# ipv6 route vrf LAN2 2111:dddd:0eee::22/128 2001:db86:0fff::2 bfd Change the BFD session parameters for static routes To change BFD session parameters for IPv4 or IPv6 static routes, use the following command in CONFIGURATION mode: bfd interval milliseconds min_rx milliseconds multiplier number role {active | passive} The following example changes the BFD session parameters for static routes: OS10(config)# bfd interval 250 min_rx 300 multiplier 4 role passive Disabling BFD for IPv6 Static Routes To disable BFD for IPv6 static routes, use the following command.
