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, use one of the following methods:
Specify an output interface and a direct next hop.
Specify an indirect next hop and a BFD packet source address for the static route.
To configure BFD control mode for an IPv6 static route (direct next hop):
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Configure BFD control mode for an IPv6 static route. | ipv6 route-static [ vpn-instance s-vpn-instance-name ] ipv6-address prefix-length interface-type interface-number next-hop-address bfd control-packet [ bfd-source ipv6-address ] [ preference preference ] [ tag tag-value ] [ description text ] | By default, BFD control mode for an IPv6 static route is not configured. |
