◆
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.

◆
VRRP advertisements from the current master virtual router include
information about its priority and current state as the master.
◆
VRRP advertisements are sent to the multicast address 224.0.0.18.
Using a multicast address reduces the amount of traffic that has to
processed by network devices that are not part of the designated VRRP
group.
◆
If the master router stops sending advertisements, backup routers will
bid to become the master router based on priority. The dead interval
