BGP or Border Gateway Protocol, is a key component of the Internet’s routing infrastructure. It is a protocol used for routing data between autonomous systems (networks) on the Internet. BGP in networking is known for its scalability and ability to handle complex routing policies. It maintains a path vector for each route, allowing network administrators to implement fine-grained routing rules. BGP routing plays a critical role in determining how data travels across the Internet and is essential for ensuring the stability and reliability of global networks. This type of routing is used by many large businesses and internet service providers for network failover and redundancy using mulit-homed connections. BGP networking is also known as Border Gateway Protocol, BGP Peering, Path Vector Protocol, Exterior Gateway Protocol, Interdomain Routing Protocol, and Internet Routing Protocol.
