Abstract
A method, system and computer program product for routing packets. A network device, e.g., router, may comprise a switch fabric coupled to a plurality of blades where each blade may comprise one or more network processors coupled to one or more physical ports. The physical ports may be connected to another one or more network devices. A plurality of physical ports across one or more blades connected to the same network device may be logically mapped into a logical interface to that network device. By logically grouping a plurality of physical ports into a logical interface to a network device, a network processor may be able to transmit packets of data to that network device across multiple ports instead of one physical port.
