mVRRP
Many VRRP backup groups run between switchs for different services. If each VRRP backup
group needs to maintain its own state machine, a large number of VRRP packets are generated
between switchs. To simplify the process and reduce the bandwidth occupied by protocol
packets, you can configure a VRRP backup group to be an mVRRP backup group and bind it
to other backup group members. Then, the status of the backup group member is determined by
the status of the bound mVRRP backup group.
VRRP6
VRRP for IPv6, also called VRRP6, is a fault-tolerant protocol functioning as an extension to
the VRRP protocol. VRRP6 groups multiple switchs into one virtual router. When the next hop
of a host fails, VRRP6 can switch services to another switch through a certain mechanism. This
thus ensures coherence and reliability of communications.
The following table shows the comparison between VRRP6 and VRRP for IPv4 based on
functions.

7.3 Configuring the VRRP Backup Group

By configuring the VRRP backup group in master/backup mode or load balancing mode, you
can implement the communication between hosts inside a LAN and external networks.

7.3.1 Establishing the Configuration Task

Before configuring a VRRP backup group, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
The VRRP backup group works in master/backup mode or load balancing mode.
