Command Usage
• 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.
• 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.
