A switch is usually dual-homed to two devices to improve network reliability. Multiple VRRP groups can be configured on the two devices to transmit various types of services. Each VRRP group needs to maintain its own state machine; therefore, a large number of VRRP Advertisement packets are transmitted between devices.

To decrease bandwidth and CPU resources occupied by protocol packets, configure a VRRP group as a management Virtual Router Redundancy Protocol (mVRRP) group and bind other VRRP groups to the mVRRP group. Figure 3-5 shows the typical mVRRP networking. The mVRRP group sends VRRP Advertisement packets to determine the master and backup status for its VRRP groups. The bound VRRP groups do not send VRRP Advertisement packets and the VRRP status is the same as the mVRRP group status.

  • mVRRP group

    An mVRRP group has all functions of a common VRRP group, and determines the statuses of its member VRRP groups by sending VRRP Advertisement packets. An mVRRP group can be deployed on the same side as service VRRP groups or on the interfaces that directly connect SwitchA and SwitchB:
    • When an mVRRP group functions as the gateway (mVRRP1 in Figure 3-5), the mVRRP group determines the Master and Backup statuses and forwards service traffic. You must first create a VRRP group and configure a virtual IP address as the gateway address, and then configure this VRRP group as an mVRRP group.

    • When an mVRRP group does not function as the gateway (mVRRP2 in Figure 3-5), the mVRRP group only determines the master and backup statuses, and cannot forward service traffic. The mVRRP group does not require a virtual IP address, and you can directly create an mVRRP group on an interface. mVRRP simplifies maintenance.

  • Service VRRP group

    After common VRRP groups are bound to an mVRRP group, they become service VRRP groups (member VRRP groups). Service VRRP groups do not need to send VRRP Advertisement packets to determine their statuses. The mVRRP group sends VRRP Advertisement packets to determine its status and the statuses of all its bound service VRRP groups.
