BFD echo packet mode
With BFD echo packet mode enabled for a static route, the outgoing interface sends BFD echo packets
to the destination device, which loops the packets back to test the link reachability.
IMPORTANT:
• Enabling BFD for a flapping route could worsen the situation.
• Do not use BFD for a static route with the outgoing interface in spoofing state.
