Creating a VRRP group and configuring virtual IP address
When creating a VRRP group on an interface, configure a virtual IP address for the VRRP group. 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 automatically created 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.
NOTE:
Do not create VRRP groups on the VLAN interface of a super VLAN. Otherwise, network performance
might be affected.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IP address on an interface, configure an IP
address for the interface and ensure that it is in the same network segment as the virtual IP address to be
configured.
