BGP (Border Gateway Protocol) is one of the core routing protocols of the internet.

BGP (Border Gateway Protocol) is a protocol for exchanging routing information between gateway hosts (each with its own router) in a network of autonomous systems.

BGP is known as a path-vector protocol, the routing table contains a list of known routers, the addresses they can reach, and a cost metric associated with the path to each router so that the best available route is chosen.
