virtual IP address may be the address of the network segment where the interface
resides, the IP address of a standby group interface or the IP address used by the
router itself (when the router is called an IP Address Owner). When the first IP
address is added to a standby group, the system will establish this standby group.
When you add a virtual IP address to the standby group later, the system will only
add this address into the virtual IP address list of this standby group. One router
interface can be added into 14 standby groups at the same time, while one
standby group can configure up to 16 virtual IP addresses. Before performing
other configuration for one standby group, the command of one virtual IP address
must be used first to establish this standby group.
