Item Description
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.
IMPORTANT:
z 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.
z 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.
z 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.
Table 3 describes the VRRP group list items.
