Configuring Distance Vector Protocols

In the preceding chapter, you gained an overview of routing protocols, including the different types and their advantages and disadvantages. This chapter covers the basic configuration of distance vector protocols, specifically the IP Routing Information Protocol (RIP) and the Interior Gateway Routing Protocol (IGRP). It focuses on the basics of these protocols; advanced configuration of these protocols is beyond the scope of this book. However, by the end of the chapter, you’ll be able to configure routers running RIP and IGRP that will route traffic in a network | CCNA CISCO CERTIFIED NETWORK ASSOCIATE 10 Configuring Distance Vector Protocols Two-Minute Drill Self Test 2 Chapter 10 Configuring Distance Vector Protocols In the preceding chapter you gained an overview of routing protocols including the different types and their advantages and disadvantages.

It focuses on the basics of these protocols advanced configuration of these protocols is beyond the scope of this book. However by the end of the chapter you ll be able to configure routers running RIP and IGRP that will route traffic in a network. CERTIFICATION OBJECTIVE IP Routing Protocol Basics Before learning about how to configure RIP and IGRP consider some basic configuration tasks that are required no matter what routing protocol you are running. You need to perform two basic steps when setting up IP routing on your router Enable the routing protocol. Assign IP addresses to your router s interfaces. at c h Memorize the two basic steps for setting up IP routing. Please note that the order of these tasks is not important. You already know how to configure an IP address on the router s interface this was discussed in Chapter 5. The following sections cover the first bullet point in more depth. The router Command Enabling an IP routing protocol is a two-step process. First you must go into Router Subconfiguration mode. This mode determines the routing protocol that you ll be running. Within this mode you ll configure the characteristics of the routing protocol. To enter the routing protocol s configuration mode use the following command Router config router name_of_the_IP_routing_protocol Router config-router The router command is used to access the routing protocol that you wish to configure it doesn t enable it. If you are not sure of the name of the routing protocol that you wish to enable
