Abstract
When a frame is received at a first port, a MCLAG learning frame transmitting unit generates a MCLAG learning frame containing a source MAC address of the frame and transmits it from a bridge port to a peer device. When the MCLAG learning frame is received and the MCLAG learning frame contains a source MAC address and does not contain a MCLAG identifier, a MCLAG learning frame receiving unit learns a second correspondence relation between a port identifier of the bridge port and the source MAC address to an address table.
