Abstract
A communication apparatus includes a receiver, a memory, a processor, and a transmitter. The receiver receives a route information frame and a first frame that is not the route information frame. The memory holds a route information table. The route information table records route information included in the route information frame. When the route information table does not include the source address of the first frame, the processor associates the source address with the address of a transfer-source apparatus that has transferred the first frame to the receiver, and registers these addresses in a registration table. In order to transmit a second frame addressed to a destination apparatus that is not recorded in the route information table, the processor obtains the address of a transfer-source apparatus registered in association with the address of the destination apparatus. The transmitter transmits the second frame to the address obtained by the processor.
