Parameter  Description 
Virtual IP Address 
Enter the virtual IPv4/IPv6 address here. This parameter will be either IPv4 or 
IPv6 depending on the Address Family selection made in the previous step. All 
routers in the same VRRP group must be configured with the same virtual router 
ID and virtual address. The IP address of the virtual router can be a real address 
configured on the routers or an unused address. If the virtual address is equal to 
the real address of the interface, this virtual router is the IP address owner. 
Advertisement Interval 
Enter the time interval value between successive advertisements by the master 
router here. The range is from 1 to 255 seconds. The master will constantly send 
VRRP advertisements. All virtual routers in a VRRP group must use the same 
timer values. 
Preemption 
Select to enable or disable the preemption feature here. This 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 of the virtual router here. The range is from 1 to 254. The 
master of a VRRP group is elected based on the priority. The virtual router with 
the highest priority becomes the master and others with lower priorities act as the 
backup for the VRRP group. If there are multiple routers with the same highest 
priority value, the router with the larger IP address will become the Master. The 
router that is the IP address owner of the VRRP group is always the master of the 
VRRP group, and has the highest priority of 255. 
Critical IP Address 
Enter the critical IP 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 address. 
Non-owner ping 
Select to enable or disable the non-owner ping feature here. This is used to 
enable a non-IP address owner virtual router in the master state to response the 
ICMP echo request for IPv4 addresses or the ND request for IPv6 addresses. 
Shutdown 
Select to enable or disable the shutdown feature here. Avoid the common mistake 
of shutting down the IP address owner routers before shutting down other non-
owner routers.
