Which of the following statements about BGP is FALSE?

The statement that BGP uses Hello messages to dynamically discover peers is false. BGP does not have a dynamic discovery mechanism; neighbors must be explicitly and manually configured on each router with their IP address and autonomous system number. BGP relies on the underlying TCP transport protocol to establish a connection to these pre-configured peers. In contrast, IGPs like OSPF and IS-IS use Hello messages to dynamically discover neighbors on a shared network segment.

B. This is a true statement. BGP is an application layer protocol that uses TCP on port 179 for reliable, connection-oriented communication.
C. This is a true statement. The OPEN message is the first message sent after TCP establishment and is used to negotiate session capabilities.
D. This is a true statement. BGP was designed as the standard Exterior Gateway Protocol (EGP) for exchanging routing information between Autonomous Systems.

1. Y. Rekhter, T. Li, S. Hares, "RFC 4271: A Border Gateway Protocol 4 (BGP-4)," IETF, January 2006, Section 1.1. "Unlike most IGPs, BGP does not use a 'hello' protocol for neighbor discovery."

2. Nokia, "7750 SR OS Router Configuration Guide," Release 22.10.R1, Part No: 3HE 18149 AAAD TQZZA, 2022, BGP Configuration Section. The documentation shows that BGP peers (neighbors) must be explicitly defined within the configuration.

3. J. Kurose, K. Ross, "Computer Networking: A Top-Down Approach," 7th ed., Pearson, 2017, Chapter 5.3. The text explains BGP's role as an inter-AS protocol and its reliance on TCP, contrasting it with the discovery mechanisms of intra-AS protocols.
