Abstract
A router programmed to function within an aggregation of a plurality of routers that appears as a single router externally is programmed to determine whether it is a first router in the aggregation of routers to receive a data packet. If the router is a first router in the aggregation of routers to receive a data packet, the router is programmed 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 then transmit the packet to another router in the aggregation of routers for layer 2 switching of the packet. If the router is not a first router in the aggregation of routers to receive a data packet, the router is programmed 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 the aggregation of routers.
