mVRRP6 is used when multiple VRRP6 groups coexist. mVRRP6 helps decrease the number of VRRP6 Advertisement packets to be sent and minimize network bandwidth consumption.
As shown in Figure 1, the switch is dual-homed to two Devices to improve the network reliability. Multiple VRRP6 groups can be configured on the two Devices to transmit various types of services. Each VRRP6 group maintains its own state machine, which causes the Devices to exchange a large number of VRRP6 Advertisement packets.
To simplify VRRP6 operations and decrease bandwidth consumption, configure a VRRP6 group as an mVRRP6 group and bind other common VRRP6 groups to the mVRRP6 group. The mVRRP6 group determines the status of the common VRRP6 groups.
Before configuring an mVRRP6 group, complete the following tasks:
Configure network layer attributes for interfaces to ensure network connectivity.
Configure basic VRRP6 functions if the mVRRP6 group functions as a gateway.
