16.4 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.
