Abstract
The subject matter described herein includes a packet forwarding device that implements next hop scaling. Rather than storing a complete set of next hop bindings at each packet processor, the storage of next hop bindings is distributed among packet processors in the packet forwarding device such that each packet processor stores next hop bindings for the hosts that are directly connected to the packet processor. For hosts that are not directly connected to a packet processor, the packet processor stores relay entries. Because of the distributed storage of next hop bindings, the number of hosts that can be served by a single packet forwarding device is increased over packet forwarding devices where each packet processor stores a complete set of next hop bindings for all connected hosts.
