The MA5600T/MA5603T/MA5608T, functioning as a UPE (underlayer PE), is located on
the edge network of HVPLS. In the downstream direction, the MA5600T/MA5603T/
MA5608T accesses multicast users through multicast VLAN whose IGMP mode is proxy
or snooping. In the upstream direction, the MA5600T/MA5603T/MA5608T is dual homed
to two AGS devices that serve as SPEs (superstratum PEs) through two PWs. The same
VSI is set up on the MA5600T/MA5603T/MA5608T and AGS and the two upstream PWs
belong to the VSI.
l
Multiple AGS devices form a VPLS core bearer network. The AGS devices learn the VPLS
multicast forwarding table and duplicate multicast traffic based on VPLS PW connections.
Two edge AGS devices functioning as SPEs in the downstream direction access the UPE
on the edge network, and two edge AGS devices functioning as PEs in the upstream
direction terminate VPLS and are connected to multicast routers.
l
Two multicast routers back up each other and import multicast traffic streams from the
multicast source to the VPLS bearer network.
NOTE
Currently, a maximum of two PWs are supported for VPLS multicast services and both two PWs are used for
transmitting multicast packets upstream.
Prerequisite
The MA5600T/MA5603T/MA5608T has been configured with multicast VLAN 100-based
multicast traffic streams, and corresponding configurations have been performed on the HG.
The configurations are similar to those for common multicast services. The difference is that
multicast upstream ports do not need to be configured for VPLS multicast services and the default
mode is used for the multicast upstream ports.
Data Plan
provides the key data plan for the MA5600T/MA5603T/MA5608T.
