21.5 MVR Overview
Multicast VLAN Registration is designed for applications (such as
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.
