Abstract
A frame relay apparatus includes an acquisition unit for acquiring a frame from an input port connected to a first subnet, a setting unit for setting an output port corresponding to a destination of the frame acquired by the acquisition unit, an assignment unit for assigning, to the frame, a flag indicating whether the output port of the frame set by the setting unit is connected to a second subnet, and a registration unit for storing the flag assigned to the frame by the assigning unit as well as a source address of the frame acquired by the acquisition unit and a port number in a learning table for storing a correspondence between an address and the port number.
