72.3.2.2 Priority
Configure the priority level (1 to 254) to set which backup router to take over in case the master router
goes down. The backup router with the highest priority will take over. The priority of the VRRP router that
owns the IP address(es) associated with the virtual router is 255.
72.3.2.3 Preempt Mode
If the master router is unavailable, a backup router assumes the role of the master router. However,
when another backup router with a higher priority joins the network, it will preempt the lower priority
backup router that is the master. Disable preempt mode to prevent this from happening.
By default, a layer 3 device with the same IP address as the virtual router will become the master router
regardless of the preempt mode.
