A disclosed searching unit searches learning tables corresponding to ports other than a first port that receives a first packet using a source address and a destination address of the first packet whose source address and destination address are not registered in a first learning table corresponding to the first port. A transferring unit transfers contents of a second learning table, corresponding to a second port, to the first learning table, in response to the searching unit finding that the source address and the destination address of the first packet are registered in the second learning table. A port from which the first packet is to be sent out is determined based on the contents transferred to the first learning table.
