22.6
MVR Overview
Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand
(MoD)) that use multicast traffic across an Ethernet ring-based 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 subscribe
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.
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
.

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.
