Congure BFD for VRRP
When using BFD with VRRP, the VRRP protocol registers with the BFD manager on the route processor module (RPM).
BFD sessions are established with all neighboring interfaces participating in VRRP. If a neighboring interface fails, the BFD agent on the line
card noties the BFD manager, which in turn noties the VRRP protocol that a link state change occurred.
Conguring BFD for VRRP is a three-step process:
1 Enable BFD globally. Refer to Enabling BFD Globally.
2 Establish VRRP BFD sessions with all VRRP-participating neighbors. Refer to Establishing VRRP Sessions on VRRP Neighbors.
3 On the master router, establish a VRRP BFD sessions with the backup routers. Refer to Establishing Sessions with All VRRP
Neighbors.

Establishing Sessions with All VRRP Neighbors
BFD sessions can be established for all VRRP neighbors at once, or a session can be established with a particular neighbor.
