mVRRP
Figure 4-8 shows mVRRP. At the aggregation layer on a MAN, a UPE is usually dual-homed
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.
NOTE
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.
The following table lists objects that can be bound to mVRRP and binding scenarios.
Table 4-4 Objects that can be bound to mVRRP and binding scenarios
Object Scenario
VRRP backup groups 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 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.
