u
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.
u
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.

u
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.
u
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.
