an entry is created in the forwarding table on the MES-2110. 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 MES-2110 to leave the multicast group. The MES-
2110 sends a query to VLAN 1 on the receiver port (in this case, a DSL port on the
MES-2110). 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 MES-2110 removes the
receiver port from the forwarding table.
