Command Usage
• A router that has a physical interface with the same IP address as that used
for the virtual router (that is, the owner of the VRRP IP address) will become
the master virtual router. The backup router with the highest priority will
become the master router if the current master fails. When the original master
router recovers, it will take over as the active master router again.
• If two or more routers are configured with the same VRRP priority, the router
with the highest IP address is elected as the new master router if the current
master fails.
• If the backup preempt function is enabled with the vrrp preempt command,
and a backup router with a priority higher than the current acting master
comes on line, this backup router will take over as the new acting master.
However, note that if the original master (i.e., the owner of the VRRP IP
address) comes back on line, it will always resume control as the master.
• If the virtual IP address for the VRRP group is the same as that of the
configured device, the priority will automatically be set to 255 prior to using
this command.
