摘要：<p>A layer-2 mobility network capable of reducing the traffic in a multicast distribution by stopping unnecessary forwarding even if all the switches constituting a sub-net do not have any function of snooping messages of multicast procedures and excellent in scalability by reducing the control traffic about the multicast procedures. A device positioned at the edge of the network snoops a report message by multicast procedures sent from a mobile terminal when the report message is sent to a gateway switch and transmits an entry update request frame for enabling the entry setting up a forwarding path for multicast to be learned toward the gateway switch. The gateway switch forwards the received report message to a port to which IP multicast router is connected after the forwarding path for multicast is set up.</p>
