As you know routers can be configured to use one or more IP routing protocols. In this chapter you learn the initial configuration of the router to enable the Routing Information Protocol RIP and the Interior Gateway Routing Protocol IGRP . In addition you learn how to monitor IP routing protocols. Please be sure to look at this chapter s associated e-Labs Videos and PhotoZooms that you will find on the CD-ROM accompanying this book. These CD elements are designed to supplement the material and reinforce the concepts introduced in this chapter. Initial Router Configuration After testing the hardware and loading the Cisco IOS Software image the router finds and applies the configuration statements. These entries provide the router with details about router-specific attributes protocol functions and interface addresses. Remember that if the router cannot locate a valid startup-config file it enters an initial router configuration mode called setup mode or system configuration dialog. With the setup mode command facility you can answer questions in the system configuration dialog. This facility prompts you for basic configuration information. The answers that you enter enable the router to build a sufficient but minimal router configuration. The setup facility provides the following An inventory of interfaces An opportunity to enter global parameters An opportunity to enter interface parameters A setup script review An opportunity to .
