Control of master selection
Selection of the master is controlled by the VRRP priority value configured in the VRID context of each router in the VR. The router configured as the owner in the VR is automatically assigned the highest VRRP priority (255) and, as long as it remains available, operates as the master router for the VR. The other routers belonging to the VR as backups are assigned the default priority value (100) and can be reconfigured to any priority value between 1 and 254, inclusive. If the current master becomes unavailable, the protocol uses the priority values configured on the other, available routers in the VR to select another router in the VR to take over the master function.
