to two NPEs. Multiple VRRP backup groups can be configured on the two NPEs to transmit

various types of services. Each VRRP backup group maintains its own state machine, leading

to transmission of a lot of VRRP Advertisement packets between NPEs. To help simplify VRRP

operation and decrease bandwidth consumption, a VRRP backup group is configured as an

mVRRP backup group. Other VRRP backup groups are bound to the mVRRP backup group and

function as service VRRP backup groups. mVRRP determines the status of its service VRRP

backup groups.

An mVRRP backup group is still a VRRP backup group essentially and has all functions that a

VRRP backup group provides.

The following table lists objects that can be bound to mVRRP and binding scenarios.

Multiple service VRRP backup groups can be bound to an mVRRP backup group. An mVRRP backup

group cannot be bound to another mVRRP backup group.

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.
