Which statements about BGP are true?

• A. BGP uses a reliable transport protocol
• B. BGP supports automatic neighbor discovery
• C. BGP supports plaintext authentication
• D. BGP supports rich routing policies

Answer: (A)

BGP, or Border Gateway Protocol, is a crucial protocol used for exchanging routing information between autonomous systems on the internet. One of its defining characteristics is that it utilizes a reliable transport protocol, specifically TCP (Transmission Control Protocol), to ensure that routing data is transmitted accurately and without loss. The reliance on TCP means that BGP benefits from the error-checking and correction mechanisms inherent in TCP, allowing it to maintain a stable and consistent routing information database. In contrast to this option, the other statements about BGP have different levels of accuracy. While BGP does allow for certain configurations like neighbor relationships, it does not inherently support automatic neighbor discovery; neighbors must be manually configured. Additionally, while BGP can utilize authentication methods, plaintext authentication is less secure compared to other mechanisms like MD5 authentication. Finally, BGP is known for its capability to implement complex routing policies, allowing for intricate management of routes based on a variety of criteria, making it a powerful tool for internet routing management. Understanding these aspects of BGP is vital for networking professionals, especially when designing and troubleshooting networks that rely on this protocol.
