Creating Vrrp Group And Configuring Virtual Ip Address - 3Com S7906E Configuration Manual

Creating VRRP Group and Configuring Virtual IP Address

You need to configure a virtual IP address for a VRRP group when creating the VRRP group on an
interface. If the interface connects to multiple sub-networks, you can configure multiple virtual IP
addresses for the VRRP group to realize router backup on different sub-networks.
A VRRP group is created automatically when you specify the first virtual IP address for the VRRP group.
If you specify another virtual IP address for the VRRP group later, the virtual IP address is added to the
virtual IP address list of the VRRP group.
It is not recommended to create VRRP groups on the VLAN interface of a super VLAN. Otherwise,
network performance may be affected.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IP address on an interface, you should first
configure an IP address for the interface and ensure that the virtual IP address to be configured is in the
same network segment as the IP address of the interface.
