Chapter 24 Multicast When the subscriber selects a television channel, computer A sends an IGMP report to the Switch to join the appropriate multicast group. If the IGMP report matches one of the configured MVR multicast group addresses on the Switch, an entry is created in the forwarding table on the Switch. This maps the subscriber VLAN to the list of forwarding destinations for the specified multicast traffic. When the subscriber changes the channel or turns off the computer, an IGMP leave message is sent to the Switch to leave the multicast group. The Switch sends a query to VLAN 1 on the receiver port (in this case, a DSL port on the Switch). If there is another subscriber device connected to this port in the same subscriber VLAN, the receiving port will still be on the list of forwarding destination for the multicast traffic. Otherwise, the Switch removes the receiver port from the forwarding table. Figure 135 MVR Multicast Television Example VLAN 1 Multicast VLAN S A 24.7 General MVR Configuration Use the MVR screen to create multicast VLANs and select the receiver port(s) and a source port for each multicast VLAN. Click Advanced Application > Multicast > Multicast Setting > MVR link to display the screen as shown next. Note: You can create up to three multicast VLANs and up to 256 multicast rules on the Switch. 230 VES1724-56 User's Guide

When the subscriber selects a television channel, computer
A
sends an IGMP report to the Switch
to join the appropriate multicast group. If the IGMP report matches one of the configured MVR
multicast group addresses on the Switch, an entry is created in the forwarding table on the Switch.
This maps the subscriber VLAN to the list of forwarding destinations for the specified multicast
traffic.
When the subscriber changes the channel or turns off the computer, an IGMP leave message is sent
to the Switch
to leave the multicast group. The Switch sends a query to VLAN 1 on the receiver port
(in this case, a DSL port on the Switch). If there is another subscriber device connected to this port
in the same subscriber VLAN, the receiving port will still be on the list of forwarding destination for
the multicast traffic. Otherwise, the Switch removes the receiver port from the forwarding table.
