Congure 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 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.
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 Establishing Sessions with All VRRP
Neighbors.
