Configure BFD for VRRP
When using BFD with VRRP, the VRRP protocol registers with the BFD manager. 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.
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
