6.3.2 Creating a Backup Group and Configuring a Virtual IP
Address
By creating a VRRP backup group, you can use the default gateway address on a LAN to be the
IP address of the VRRP backup group.
Context
Do as follows on each switch of a backup group:
Perform the following step as required to configure VRRP for IPv4 or VRRP for IPv6.

– The switch with the highest priority in the backup group serves as the master switch
and undertakes the services.
– Except for the master switch, other switchs in the backup group serve as the backup
switchs and work in the Backup state.
– If the master switch fails, backup switchs select a new master switch based on their
priorities to provide routing service.
In the load balancing mode, multiple backup groups are created to share the traffic of a
network. One switch can join different backup groups. The load balancing mode is as
follows:
– Switch A serves as the master device in backup group 1 and the backup device in backup
group 2.
– Switch B serves as the master device in backup group 2 and the backup device in backup
group 1.
– Some hosts on the network use backup group 1 as their gateway and others use backup
group 2 as their gateway.
In this case, they can back up each other and share the traffic.
