In this chapter, you learned about selecting routing protocols for enterprise networks. The following topics were explored:
■ Static versus dynamic routing
■ Interior versus exterior gateway routing protocols
■ Distance vector versus link-state versus hybrid routing protocols
■ Routing protocol metrics
■ Routing protocol convergence
■ Flat versus hierarchical protocols
■ EIGRP, a Cisco-proprietary routing protocol that includes a topology table for maintaining all routes received from its neighbors. The best of these routes are put in the routing table.
■ OSPF, an open-standard protocol that was developed to overcome the limitations of RIP
■ Integrated IS-IS, a routing protocol designed for the OSI protocol suite and adapted for IP
■ BGP, an exterior routing protocol primarily used for inter-AS routing
■ Route redistribution use in a network running multiple routing protocols
■ Route filtering to prevent the advertisement of certain routes through the routing domain
■ Route summarization to represent a series of routes by a single summary address
