As shown in
are deployed for high reliability. The master and standby routeres are determined by mVRRP
between NPEs.
The mVRRP backup group is actually the ordinary VRRP backup group. The difference is that
the mVRRP backup group can be bound to other backup groups of different services. The status
of the backup group of related services depends on the binding relationship.
The mVRRP backup group can be bound to several backup group members. The mVRRP backup
group cannot be bound to other management backup groups.
According to different applications, the binding relationship of the mVRRP backup group is as
follows:

Figure 4-4, when the convergence layer of the Metro Ethernet (ME) dual NPEs
The VRRP backup group is bound to the mVRRP backup group: UPEs are dual-homed to
NPEs. VRRP is run between NPEs. The master NPE and backup NPE are determined by
the configured priority of VRRP. Multiple VRRP backup groups run between NPEs with
different services.
If each VRRP backup group needs to maintain its own state machine, a huge number of
VRRP packets exist among NPEs. To simplify the process and decrease occupancy of
bandwidth, you can set one VRRP backup group as the mVRRP backup group. Other
backup group members are bound to the mVRRP backup group. The master and slave
routeres are determined directly by the binding relationship.
The service interfaces are bound to the mVRRP backup group. If the UPEs are dual-homed
to NPEs through two physical links. You can bind the member interfaces to the mVRRP
backup group to determine the master member interfaces and the slave interfaces.
PW is bound to the mVRRP backup group. If VPLS is run between UPEs and NPEs, the
UPEs are dual-homed to NPEs through two PWs. Then, you can bind the PW and the
mVRRP backup group to determine the master PW and the slave PW.
