General Mvr Configuration - ZyXEL Communications MES3500-24S User Manual

Chapter 25 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, an uplink 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.
