Configuring 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):

Configuring single-hop echo mode
With BFD echo mode enabled for a static route, the output interface sends BFD echo packets to the
destination device, which loops the packets back to test the link reachability.
IMPORTANT:
Do not use BFD for a static route with the output interface in spoofing state.
