Apparatus, system, and method for improved memory consumption in network devices via efficient route management

摘要

The disclosed computer-implemented method may include (1) receiving, at a network device, a route update for one or more routes that direct traffic within a network that supports BGP, (2) identifying, within the route update, a BGP prefix and a plurality of protocol next-hop addresses that (A) identify a plurality of neighbors of the network device and (B) each correspond to the BGP prefix, (3) maintaining a single copy of the BGP prefix and each of the protocol next-hop addresses, (4) receiving a packet destined for a computing device that is reachable via at least one of the neighbors of the network device, and then (5) forwarding the packet to the one of the neighbors of the network device in accordance with the BGP prefix and the protocol next-hop address that identifies the one of the neighbors. Various other methods, systems, and apparatuses are also disclosed.
