Create standby group and
configure virtual IP
address of the standby
group
Caution:
The maximum number of standby groups on an interface and the maximum number
of virtual IP addresses in a standby group vary by device.
A standby group is removed after you remove all the virtual IP addresses in it. In
addition, configurations on that standby group no longer take effect.
The virtual IP address of the virtual router can be either an unused IP address on the
segment where the standby group resides or the IP address of an interface on a
switch in the standby group. In the latter case, the switch is called the IP address
owner.
The virtual IP address of the standby group cannot be 0.0.0.0, 255.255.255.255,
loopback address, non A/B/C address and other illegal IP addresses such as
0.0.0.1.
Only when the configured virtual IP address and the interface IP address belong to
the same segment and are legal host addresses can the standby group operate
normally. 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 standby group is always initialize though you
can perform the configuration successfully, that is, VRRP does not take effect in this
case.
