Bidirectional control mode

To use BFD bidirectional control detection between two devices, enable BFD control mode for each device's static route destined to the peer.

To configure a static route and enable BFD control mode for it, specify an output interface and a direct next hop, or specify an indirect next hop and a specific BFD packet source address for the static route.

To configure BFD control mode for a static route (direct next hop):

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Configure BFD control mode for a static route.	Method 1:ip route-static dest-address { mask-length \| mask } interface-type interface-number next-hop-address bfd control-packet [ preference preference-value ] [ tag tag-value ] [ description description-text ] Method 2:ip route-static vpn-instance s-vpn-instance-name dest-address { mask-length \| mask } interface-type interface-number next-hop-address bfd control-packet [ preference preference-value ] [ tag tag-value ] [ description description-text ]	Use either method. By default, BFD control mode for a static route is not configured.
