Border Gateway Protocol (BGP)

Border Gateway Protocol (BGP) is a protocol used for exchanging routing and reachability information between autonomous systems (ASes) on the Internet. It is a path vector routing protocol, which means that it advertises the paths that it has learned to other ASes. BGP is used to determine the best path to a destination network, taking into account factors such as cost, reliability, and policy.

How BGP Works

BGP operates on a peer-to-peer basis, with each AS exchanging routing information with its neighbors. When an AS learns of a new route, it advertises that route to its neighbors. The neighbors then evaluate the route and either accept it or reject it. If a neighbor accepts a route, it advertises that route to its own neighbors. This process continues until the route is either withdrawn or reaches its destination.

BGP Features

BGP has a number of features that make it well-suited for use on the Internet. These features include:

• Path vector routing: BGP advertises the paths that it has learned, rather than the destinations that it can reach. This allows BGP to be used to route traffic across multiple ASes, even if those ASes do not have a direct connection to each other.
• Policy-based routing: BGP allows ASes to implement routing policies that control how traffic is forwarded. These policies can be used to prioritize certain types of traffic, or to block traffic from certain sources.
• Graceful convergence: BGP is designed to converge quickly and gracefully when there is a change in the network topology. This helps to prevent traffic outages and disruptions.

Why Learn BGP?
