Routing Protocol Basics

A routing protocol (for example, RIP, OSPF, or EIGRP) is a protocol that advertises route
information between routers. Conversely, a routed protocol is a protocol with an addressing scheme (for example, IP) that defines different network addresses. Traffic can then be routed between defined networks, perhaps with the assistance of a routing protocol. 
This section looks at routing protocol characteristics, such as how believable a routing protocol is versus other routing protocols. Also, in the presence of multiple routes, different routing protocols use different metrics to determine the best path.
