A switch is dual-homed to two routers at the aggregation layer on a metropolitan area network (MAN). Multiple VRRP backup groups can be configured on the two routers to transmit various types of services. Because each VRRP backup group must maintain its own state machine, a large number of VRRP Advertisement packets are transmitted between the routers.

To help reduce bandwidth and CPU resource consumption during VRRP packet transmission, a VRRP backup group can be configured as a management Virtual Router Redundancy Protocol (mVRRP) backup group. Other VRRP backup groups are bound to the mVRRP backup group and become service VRRP backup groups. Only the mVRRP backup group sends VRRP packets to negotiate the master/backup status. The mVRRP backup group determines the master/backup status of service VRRP backup groups.

As shown in figure , an mVRRP backup group can be deployed on the same side as service VRRP backup groups or on the interfaces that directly connect Device A and Device B.
