fails. However, because the priority of the virtual IP address Owner is
the highest, the original master router will always become the active
master router when it recovers.
• If two or more routers are configured with the same VRRP priority, the
router with the higher IP address is elected as the new master router if
the current master fails.
Preempting the Acting Master –
• The virtual IP Owner has the highest priority, so no other router can
preempt it, and it will always resume control as the master virtual router
when it comes back on line. The preempt function only allows a
backup router to take over from another backup router that is
temporarily acting as the group master. If preemption is enabled and
this router has a higher priority than the current acting master when it
comes on line, it will take over as the acting group master.
• You can add a delay to the preempt function to 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 master
router.
