Lab Requirements:to be able to perform the tasks in this lab you need 2 Cisco routers connected to each other. In this TechLan we assumed two 2501 routers, but pretty much set of routers will do. This lab does not cover how to physically connect the routers and the hosts, but rather assumes you can tell by looking at the diagram. If you need information on how to setup your lab physically, please refer to ourSetting up the Hardware TechLab.
This lab comes in three versions, the one you are looking at, a printer-friendly version with the commands, and a printer-friendly version without the commands that can be used as an assessment. The printer-friendly versions are for members only. Also note the the commands in this lab often include the router command prompt and never use the abbreviated form.
This first CCNA TechLab covers a couple of basic configuration tasks, such as setting passwords and enabling IP routing using RIP. You will need a lab setup similar to the network diagram below:
Before you start, make sure you clear both routers’ configuration using theRouter#erase startup-configcommand. First we will configure RouterA, after the router reboots, the following message will be displayed:
% Please answer ‘yes’ or ‘no’.
Would you like to enter the initial configuration dialog? [yes/no]
Typenoand press ENTER. Press ENTER again when the messagePress RETURN to get startedenableat theRouter>command prompt to enter Privileged Exec mode, notice the prompt chances toRouter#.
CONFIGURING THE FIRST ROUTER
STEP 1. Change the router’s host name to RouterA
Enter configuration mode using the following command:
Router#configure terminal
Change the host name of the router to RouterA using the following command :
Router(config)#hostname RouterA
RouterA(config)#
Notice how changing the hostname immediately affects the prompt. Remember that you are configuring therunningconfiguration.
STEP 2. Disable domain lookups
To prevent the router from interpreting every incorrectly typed command as a host name and trying to resolve it to an IP address to setup a telnet connection with it, use the following command:
