BCG
The Border Gateway Protocol (BGP) is the standard protocol for exchanging routing information between autonomous systems on the Internet, enabling scalable, policy-driven inter-domain routing.
BGP (Border Gateway Protocol) is a path vector protocol that enables routers within and between autonomous systems (ASes) to exchange routing information and make policy-based routing decisions. It is essential for global Internet routing, supporting interconnection between ISPs and multi-homed organizations.
BGP operates over TCP, supports route aggregation, and provides mechanisms for route authentication and security. Its scalability and flexibility make it the backbone of the Internet and large-scale enterprise and cloud networks.
Best practices include implementing route filtering, monitoring for route leaks, and securing BGP sessions to prevent hijacking and other attacks.
