Parameter Description
Advertisement Interval
Enter the advertisement interval value here. This is the time interval between
successive VRRP advertisements by the master router. The range is from 1 to 255
seconds. By default, this value is 1 second.
Preemption
Select to enable or disable the preemption feature here. This feature is used to
allow a router to take over the master role if it has a better priority than the current
master.
Priority
Enter the priority value here. The range is from 1 to 254.
Critical IP Address
Enter the critical IPv4 address here. If the critical IP is configured on one virtual
router, the virtual router cannot be activated when the critical IP address is
unreachable. One VRRP group can only track one critical IP.
Shutdown
Select to enable or disable the shutdown feature here. This feature is used to
disable a virtual router on an interface. Avoid the common mistake of shutting
down the IP address owner router before shutting down other non-owner routers.
