ABSTRACT:
When an apparatus located at an edge of a network transmits a report message in a multicast procedure transmitted from a mobile terminal to a gateway switch, the apparatus snoops the report message and transmits an entry update request frame for causing an entry forming a transfer route for multicast to be learned in a direction of the gateway switch. The gateway switch transfers the received report message to a port to which an IP multicast router is connected after the transfer router for multicast is formed.
