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.
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.
