A method and apparatus for a router to inform a Layer 2 switch by use of packets of a new router group port management protocol (RGMP) that the layer 2 switch is to forward multicast packets of a specified group to the router. First the router transmits a RGMP HELLO packet to the layer 2 switch to inform the switch that the router is a multicast router implementing the invention. Then, in the event that the router receives an IGMP packet from an end station requesting multicast packets of a particular group, in response the router sends an RGMP JOIN packet to the layer 2 switch. The RGMP JOIN packet requests that the layer 2 switch forward only multicast group packets, of the group whose group number is written into a field of the RGMP JOIN packet, to the router. Also, the router sends a prior art PIM JOIN packet to other multicast routers in order to be placed on the multicast distribution tree for that group. The layer 2 switch builds a forwarding table for multicast groups listing ports connected to routers having sent a RGMP JOIN for that group. When a multicast group packet arrives at the layer 2 switch, the switch uses the forwarding table to forward the packet only to those routers requesting that group.

The invention aims at providing a server which manages address information for servers subordinate to a port-forwarding relay device (router) thus allowing an access from a wide area network. A representative server issues a request to assign a default port number to a router. The port management unit of the representative server registered to a default port number acquires the IP address of the router (wide area network address) and port mapping information (port number information on other equipment) from the router and retains the information acquired. In case it is determined that an access from the wide area network is first directed to a representative server, the representative server displays in a list the port number information on the accessing terminal in response to an access from the wide area network. This allows an external user to readily access desired equipment. The representative server periodically makes a port mapping information to the router and updates the information.
