Abstract:
1. A router programmed to function within an aggregation of a plurality of routers that appears as a single router externally, the router comprising: a processor to determine whether said router is a first router in said aggregation of routers to receive a data packet, and Management Information Base (MIB) parameters indicating which routers are interconnected so as to form said aggregation of routers and make the aggregation of routers appear to a device external to the aggregation of routers as a single router, if said router is a first router in said aggregation of routers to receive a data packet, said processor to perform layer 3 routing for the data packet including modification of the source and destination Media Access Control (MAC) addresses of the packet, and transmit the packet to another router in said aggregation of routers for layer 2 switching of the packet, and if said router is not a first router in said aggregation of routers to receive a data packet, said processor to only perform layer 2 switching of the packet, with layer 3 routing for the data packet having already been performed by another router in said aggregation of routers.
