Abstract
A method and system for preventing excessive flood packets from switching devices in a network for routing packets between a source station having an address and a destination station in the network having an address. A first packet directed toward the destination station is received over the network via an incoming traffic switch. The incoming traffic switch includes a table without the address of the destination station. The first packet is flooded over the plurality of switches. The flooded first packet is received at a front facing switch coupled to the destination station. The front facing switch has a table including the source address of the packet. The source address of packet is flushed from the table of the front facing switch. A response packet is sent from the destination station to the source station. The response packet is flooded to the incoming traffic switch. The flooded response packet is received at the incoming traffic switch. The table of the incoming traffic switch is updated with the address of the destination station.
