Border Gateway Protocol

(Computers) protocol used for exchanging routing information between gateway hosts on large networks (such as the Internet), BGP

The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It works by maintaining a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional IGP metrics, but makes routing decisions based on path, network policies and/or rulesets.

(BGP) An Exterior Gateway Protocol defined in RFC 1267 and RFC 1268. Its design is based on experience gained with Exterior Gateway Protocol (EGP), as defined in STD 18, RFC 904 and EGP usage in the NSFNet backbone, as described in RFCs 1092 and 1093.
