Abstract
A network comprising a switch configured to learn a source address (SA) for a source node with a source port that receives a frame comprising the SA if the SA is not previously learned on another port and to subsequently forward any frame comprising a destination address (DA) for a destination node that matches the learned SA on the source port associated with the SA. A network comprising a switch configured to flood a frame received on a receiving port if the frame comprises a DA that is not previously learned on a source port and to distinguish the flooded frame from other forwarded frames by labeling the flooded frame, wherein the frame is flooded on a plurality of ports. A method comprising disabling a plurality of filtering database (FDB) entries that correspond to a plurality of addresses that are associated with a port, and sending the addresses in a control frame.
