Border gateway protocol (BGP) routing is the process of routing Internet data and packets using the BGP protocol.
It enables communicating and exchanging routing information across the Internet and autonomous systems, as well as connecting or communicating between Internet service providers (ISP) or to the external borders of enterprise networks.
Techopedia Explains Border Gateway Protocol Routing
BGP routing utilizes information from available paths, path attributes and network routing policies implemented by the network administrators to route data/packets. Such path attributes help the BGP protocol in selecting the optimal path based on the conditions at hand. BGP routing is considered to be one of the most important routing processes that enable the sending of data over the Internet.
BGP routing manages incoming and outgoing routing tables to store inward and outward routing paths. Every time a routing process is initiated, these tables are accessed to select a path/route.
