24.6  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 (12 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

non-volatile memory when you are done configuring.
