VRID Display group number of the VRRP group.
Virtual IP
Configure the virtual IP address of the VRRP group.
If an interface connects to multiple subnets, you can configure multiple virtual IP
addresses for the VRRP group to implement router backup on different subnets.
IMPORTANT:
• The virtual IP address cannot be 0.0.0.0, 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.
Therefore, you can modify the IP address of the interface on the IP address owner
to resolve the collision.
• The VRRP group can operate properly only when the configured virtual IP
address and the interface IP address belong to the same segment and are valid
host addresses. 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 to which
the interface IP address belongs, the state of the VRRP group is not always
initialize though you can perform the configuration successfully, that is, VRRP
does not take effect in this case.
