Configure 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 notifies the
BFD manager, which in turn notifies the VRRP protocol that a link state change occurred.
Configuring BFD for VRRP is a three-step process:
1 Enable BFD globally. Refer to
2 Establish VRRP BFD sessions with all VRRP-participating neighbors.
3 On the master router, establish a VRRP BFD sessions with the backup routers. Refer to
Neighbors.
