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. Figure 102 MVR Network Example 23.6.1 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. MES-3528 User's Guide 189
