Specify the type of the MAC addresses mapped to the virtual IP addresses before creating a
VRRP group. Otherwise, you cannot change the type of the MAC addresses mapped to virtual
IP addresses.
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.
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, 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.
