Implementation of Border Gateway Protocol (BGP) Attributes

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP implements routing policies based on a set of attributes accompanying each route used to choose the “shortest” path across multiple ASs. It also controlled by one or more routing policies. This paper describes implementation of BGP and BGP attributes using GNS3 and Cisco router Image. We include on this paper the comparative results for different BGP attributes implementation, in addition how these attributes affect routing path.
