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 Establishing Sessions with All VRRP Neighbors. Related Configuration Tasks • Changing VRRP Session Parameters. • Establishing Sessions with OSPF Neighbors.
