EGPs (Exterior Gateway Protocols) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. The Internet and TCP/IP networks are divided into autonomous systems, which are collections of hosts and routers that typically use the same routing protocol and are administered by the same authority. There are two categories of routing protocols to handle traffic for domains. While interior routing protocols are used within a domain, exterior routing protocols provide a way for two neighboring routers located at the edges of their respective domains to exchange routing information. The primary interior routing protocols in use today are RIP (Routing Information Protocol) and OSPF (Open Shortest Path First). OSPF is now the most important on large networks and Internet service provider networks, but RIP is still popular for small private networks. The primary exterior routing protocol for exchanging routing information between autonomous systems is BGP (Border Gateway Protocol). An earlier protocol for doing this was EGP (Exterior Gateway Protocol), but it was replaced by BGP. The topic "Routing on the Internet" provides more information about these protocols.
