BGP
Border Gateway Protocol (BGP) is a standardized routing protocol that is used to route traffic across the internet. It exchanges routing information between Autonomous Systems (AS) on the internet and makes routing decisions based on path, network policies, and rule sets. BGP contains two distinct subsets: internal BGP (iBGP) and external BGP (eBGP). iBGP is intended for use within your own networks. eBGP is used to connect different networks together and is the main routing protocol for the internet backbone.
