Abstract
In one embodiment, a first packet is forwarded based on a network layer routing decision rendered by a router. A shortcut entry is generated based on a first header of the first packet. The shortcut entry is stored. In response to the shortcut entry, and absent a network layer routing decision rendered by a router, subsequent packets having a subsequent header are forwarded if the subsequent header has at least one field which matches a field of the first header. Such technique may be implemented by a switch coupled to the router.
