Multicast VLAN Registration

This chapter introduces and shows you how to configure Multicast VLAN Registration
(MVR).

23.1 MVR Overview

Multicast VLAN Registration is designed for applications (such as Media-on-Demand (MoD))
that use multicast traffic across a service provider network.
MVR allows one single multicast VLAN to be shared among different subscriber VLANs on
the network. While isolated in different subscriber VLANs, connected devices can subscriber
to and unsubscribe from the multicast stream in the multicast VLAN. This improves
bandwidth utilization with reduced multicast traffic in the subscriber VLANs and simplifies
multicast group management.
You must enable IGMP snooping to use MVR. However, MVR only responds to IGMP join
and leave control messages from multicast groups that are configured under MVR. Join and
leave reports from other multicast groups are managed by IGMP snooping.
The following figure shows a network example. The subscriber VLAN (1, 2 and 3)
information is hidden from the streaming media server, S. In addition, the multicast VLAN
information is only visible to the switch and S.

23.1.1 Types of MVR Ports

In MVR, a source port is a port on the switch that can send and receive multicast traffic in a
multicast VLAN while a receiver port can only receive multicast traffic. Once configured, the
switch maintains a forwarding table that matches the multicast stream to the associated
multicast group.

23.1.2 MVR Modes

You can set your switch to operate in either dynamic or compatible mode.
