Step 2. Configure BFD control mode for a static route. Command • Approach 1: ip route-static dest-address { mask | mask-length } next-hop-address bfd control-packet bfd-source ip-address [ preference preference-value ] [ tag tag-value ] [ description description-text ] • Approach 2: ip route-static vpn-instance s-vpn-instance-name& dest-address { mask | mask-length } next-hop-address bfd control-packet bfd-source ip-address [ preference preference-value ] [ tag tag-value ] [ description description-text ] Remarks Use either command. BFD echo mode IMPORTANT: • Enabling BFD for a flapping route could worsen the situation. Therefore, use it with caution. • Do not use BFD for a static route with the output interface having the spoofing attribute. With BFD echo mode enabled for a static route, the local device sends BFD echo packets to the peer, which loops it back to test the link. For the echo mode, only one end needs to establish the BFD session, and the source address of echo packets must be configured. To configure BFD echo mode for static routes: Step 1. Enter system view. 2. Configure the source address of echo packets. 3. Enable BFD echo mode for static routes. Command Remarks system-view N/A bfd echo-source-ip ip-address • Approach 1: ip route-static dest-address { mask | mask-length } interface-type interface-number next-hop-address bfd echo-packet [ preference preference-value ] [ tag tag-value ] [ description description-text ] • Approach 2: ip route-static vpn-instance s-vpn-instance-name& dest-address { mask | mask-length } interface-type interface-number next-hop-address bfd echo-packet [ preference preference-value ] [ tag tag-value ] [ description description-text ] Not configured by default. For more information about this command, see High Availability Command Reference. Use either approach. Displaying and maintaining static routes 9
