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 a static
route, you must specify both an output interface and a next hop for the static route.
To configure BFD echo mode for static routes:
Step
1. Enter system view.
