ABSTRACT:
A communication system includes a relay apparatus which offers an access link to a mobile terminal, a layer 2 switch which relays data between the relay apparatus and a router on a next hop from a communication destination terminal of the mobile terminal, and a route information notification unit. The route information notification unit notifies, to the relay apparatus and the layer 2 switch in a subnet where the mobile terminal is present, route information including a data link layer unicast address of a packet addressed to the mobile terminal, and a data link layer multicast address thereof in a case where the mobile terminal is activated and in a case where the mobile terminal switches a connection.
