Border Gateway Protocol (BGP) is the standard exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. It is the glue of the Internet and a fundamental part of its infrastructure. However, it is also a prime target for attacks—if compromised, attackers can disrupt Internet connectivity.
This project explores how BGP interconnects the Internet, demonstrating its functionality using an Internet Emulator. Through a series of experiments, we analyze BGP operations, configure stub and transit autonomous systems, and simulate a network prefix hijacking attack.
