Command Usage
â—† If preempt is enabled, and this backup router has a priority higher than the
current acting master, it will take over as the new 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.
â—† The delay can give additional time to receive an advertisement message from
the current master before taking control. If the router attempting to become
the master has just come on line, this delay also gives it time to gather
information for its routing table before actually preempting the currently active
router.
Example
Console(config-if)#vrrp 1 preempt delay 10
Console(config-if)#

Command Usage
â—† 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.
