The chapter discusses IP routing and routing protocols. It explains the goals of routing which include stability, robustness, dynamic path updates, and secure information transmission. It also covers routing metrics, interior and exterior routing protocols, static and dynamic routing, routing tables, and the Routing Information Protocol (RIP). RIP uses hop count as its metric and supports up to 15 hops between routers. Enhancements in RIPv2 include multicast updates, triggered updates, classless operation, and authentication.
