Case Study: Securing the BGP Routing Protocol

This case study looks at how various features available in BGP can be used to strengthen and secure the BGP protocol. It is important to note that although quite a few of the suggestions in this section can be implemented in BGP networks, others might not be suitable for certain networks. You must thoroughly understand how BGP is implemented on a network to be able to suitably apply some of the suggestions culled from this case study.

BGP is the routing protocol that runs most of the interdomain routing on the Internet today. It is also used within large networks. However, for the most part, other interior gateway protocols are used on smaller networks, and then BGP is used to bind these networks ...
