BFD control packet mode
To use BFD control packets for bidirectional detection between two devices, you need to enable BFD
control packet mode for each device's static route destined to the peer.
Follow these steps to configure BFD control packet mode for static routes:
To do...
Enter system view
Enable BFD control
packet mode for static
routes
BFD echo packet mode
With BFD echo packet mode enabled for a static route, the local device sends BFD echo packets to the
peer, which loops it back to test the link in between.
Follow these steps to configure BFD echo packet mode for static routes:
To do...
Enter system view
Configure the source
address of echo
packets
Enable BFD echo
packet mode for static
routes
Use the command...
system-view
ip route-static dest-address { mask | mask-length }
interface-type interface-number next-hop-address bfd
