To establish sessions with all VRRP neighbors:
Step Task
1 Establish sessions with all VRRP neighbors.
Establishing VRRP sessions on VRRP neighbors
The master router does not care about the state of the backup router, so it does not participate in any VRRP
BFD sessions. Therefore, VRRP BFD sessions on the backup router cannot change to the UP state. The
master router must be configured to establish an individual VRRP session the backup router.
To establish a session with a particular VRRP neighbor:
Step Task
1 Establish a session with a particular VRRP
neighbor.
