Border Gateway Protocol -The Language of the Internet

This paper is an examination of Border Gateway Protocol. The intent is to introduce to the reader the concepts involved with routing across the Internet and examine a sample BGP configuration on a Cisco router. The sample will include only the statements that directly apply to the BGP configuration and will not include any interfaces, IP routes, or information pertaining to any other routing protocol, although all of this information would be necessary to have a functioning BGP router. The study of BGP is much larger than this paper will detail. In conclusion there will be a consideration of S-BGP, an option currently underway to increase the level of security on the Internet.
