9.4. Internet Routing Protocols
As mentioned earlier, Internet routing protocols can be classified into interdomain and intradomain routing protocols. Interdomain routing protocols are also referred to as Exterior Gateway Protocols or EGPs, based on early Internet terminology. BGP is the most popular example of an EGP. In fact, it is the only EGP that is in use in the Internet today. Intradomain routing protocols, on the other hand, are referred to as Interior Gateway Protocols or IGPs. Examples of IGPs include OSPF, IS-IS, and RIP. Figure 9-4 gives an overview of different routing protocols running in the Internet.
