Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In network routing, BGP confederation is a method to use BGP to subdivide a single autonomous system (AS) into multiple internal sub-AS's, yet still advertise as a single AS to external peers. The intent is to reduce IBGP mesh size. Routing (or routeing) is the process of selecting paths in a network along which to send network traffic. Routing is performed for many kinds of networks, including the telephone network (Circuit switching) , electronic data networks (such as the Internet), and transportation networks. This article is concerned primarily with routing in electronic data networks using packet switching technology.
