The Border Gateway Protocol, also known as BGP, is an external routing protocol whose function is to connect the various autonomous systems on the Internet through the exchange of routing and reachability information. It is currently in the fourth version (BGP-4) and has been, since 19964, the main Internet routing protocol for Internet Service Providers (ISPs) to establish connections to each other. Therefore, given the importance of BGP, this paper aims to perform a comparative performance analysis between two different scenarios: a basic configuration with the minimum requirements to perform the routing between autonomous systems and another configuration with the MD5 TCP authentication implementation, whose objective is to mitigate some types of attack to the BGP. These two scenarios underwent three standardized tests that verified the response time between two end devices in different autonomous systems, the BGP convergence time to a redundant link and the CPU utilization in the router. The results showed that the option of BGP with authentication is preferable given that the performance was slightly impacted.
