What is BGP Routing?
BGP routing (Border Gateway Protocol routing) is a fundamental component of the internet infrastructure that establishes and controls data paths across the internet. BGP is a policy-based routing protocol that ensures the efficient and reliable transfer of data packets across different autonomous systems (AS) on the internet. Each autonomous system, representing a distinct network, uses BGP to advertise its network reachability information to other systems, essentially informing them about the routes data packets can take to reach specific destinations within the network.
BGP routing involves key elements like autonomous systems, routes, border routers, and peering.
