The fields that can be configured are described below: 
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. 
BFD Remote IP 
Enter the Bidirectional Forwarding Detection (BFD) remote IP address here. This 
IP address must be a real IP address of a real device in the same VRRP virtual 
group. A BFD session will be created between this VRRP router and its peer. 
When the session goes down, if the VRRP is in the backup state, it will Switch to 
master fast. 
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.
