Chapter 28 Configuring IGMP Snooping and Filtering, and MVR
Understanding Multicast VLAN Registration
• In dynamic mode, the interface on which the multicast router is learned or configured will receive
MVR traffic. The receiver ports from where the MVR hosts have explicitly joined either by IGMP
reports or by MVR static configuration will receive the MVR data traffic. The IGMP reports are
forwarded to all the multicast VLAN (mVLAN) mrouter ports.
Using MVR in a Multicast Television Application
In a multicast television application, a PC or a television with a set-top box can receive the multicast
stream. Multiple set-top boxes or PCs can be connected to one subscriber port, which is a switch port
configured as an MVR receiver port. Figure 28-1 is an example configuration. DHCP assigns an IP
address to the set-top box or the PC. When a subscriber selects a channel, the set-top box or PC sends
an IGMP report to Switch A to join the appropriate multicast. If the IGMP report matches one of the
configured IP multicast group addresses, the switch CPU modifies the hardware address table to include
this receiver port and VLAN as a forwarding destination of the specified multicast stream when it is
received from the multicast VLAN. Uplink ports that send and receive multicast data to and from the
multicast VLAN are called MVR source ports.
