BGP Interview Questions and Answers

BGP, or Border Gateway Protocol, is a standardized exterior gateway protocol used to facilitate the exchange of routing and reachability information between different autonomous systems (AS) on the internet. As the primary routing protocol of the internet, BGP enables routers within and between ASs to dynamically learn, advertise, and select the best paths for data packets.

Unlike interior gateway protocols such as OSPF or EIGRP, BGP focuses on inter-domain routing, making it crucial for internet service providers and large organizations managing complex networks. BGP operates on the basis of policy rules, allowing administrators to influence traffic routing decisions based on various criteria.
