VRID Set the group number of the VRRP group.
Virtual IP
• Configure the virtual IP address of the VRRP group.
• If the VRRP interface connects to multiple subnets, you can configure multiple virtual IP
addresses for the VRRP group to implement router backup on different subnets.
TIP:
• The virtual IP address cannot be all 0s (0.0.0.0), a broadcast address (255.255.255.255),
a loopback address, any other invalid IP address (like 0.0.0.1), or an address that does not
belong to class A, B or C.
• The virtual IP address can be either an unused IP address on the segment where the VRRP
group resides or the IP address of an interface on a router in the VRRP group. In the latter
case, the router is called the IP address owner. Removal of the VRRP group on the IP address
owner will cause IP address collision. In such a case, it is recommended to modify the IP
address of the interface on the IP address owner to resolve the collision.
• The VRRP group can operate normally only when the virtual IP address is valid and on the
same network segment with the interface IP address. If the configured virtual IP address and
the interface IP address do not belong to the same network segment, or the configured IP
address is the network address or network broadcast address of the network segment that the
interface IP address belongs to, the state of the VRRP group is always initialize though you
can perform the configuration successfully, that is, VRRP does not take effect in this case.

Run Priority
Running status of a router, that is, the current status of the router. After you configure
to monitor the specified interface or Track object, the priority of a router changes with
the change of the interface or Track object.

or Initialize.

Configuration on Interface page, as shown in Figure 9. C
lick the icon corresponding to the VRRP
group to be configured to enter the Modify VRRP Group page, and then click Display Track Config to
