Advertisement packets from using too many bandwidth resources. On a Virtual Private
LAN Service (VPLS) network, pseudo wires (PWs) or VRRP-disabled interfaces can be
bound to the mVRRP backup group. The mVRRP backup group helps PWs or VRRP-
disabled interfaces perform a traffic switchover, ensuring uninterrupted traffic
transmission.
VRRP association is configured. If a link fails or a network configuration is changed, a
master/backup VRRP switchover is performed. This process ensures that traffic is properly
transmitted.

Scenario
If multiple VRRP backup groups are configured on a device, they
can be bound to an mVRRP backup group. The mVRRP backup
group sends VRRP Advertisement packets to determine the master
and backup status for its service VRRP backup groups.
VRRP-disabled interfaces can be bound to an mVRRP backup
group. A master/slave mVRRP switchover can trigger the active/
standby switchover on these interfaces, preventing traffic loss.
mVRRP is bound to PWs. After a master/slave mVRRP switchover
is performed, the mVRRP status determines the primary and
secondary states for PWs, preventing traffic loss.

Usage Scenario
VRRP detects status changes in interfaces only in a
VRRP backup group. VRRP can be associated with
a specified interface that is not in the VRRP backup
group. If the monitored interface's status changes,
the VRRP-enabled devices change the VRRP
priority values and elect a master device.
