A spanning tree bypassing apparatus comprising:

• means for sending a first frame, whose destination address is a first address, out on a designated port as well as on a root port when the first frame is received, provided that learning is done on the root port so as to send any frame destined for the first address out on the root port;
• and means for sending a second frame, whose destination address is a second address, out on a blocking port when the second frame is received after a third frame whose source address is the second address was received on the blocking port,
• wherein the blocking port send out means includes:
• means for performing temporary learning so as to send any frame destined for the second address out on the blocking port, when the third frame is received on the blocking port;
• and
• means for sending the second frame, whose destination address is the second address, out on the blocking port by switching the temporary learning to normal learning when the second frame is received.
