Lab 8.2.1 Individual router config. - Overview
Estimated time: 30 min.
Objectives:
 Configure a router for the standard lab setup using only the lab diagram
 Configure the router using only the Command Line Interface (CLI)
 Configure workstation IP address settings to communicate with the router via Ethernet
 Prepare for Part A of the Final Exam (Timed Router Configuration)
Background:
In this lab you will configure one of the five lab routers from the command line by yourself
without the use of any notes, only the network topology. You may use the router help facility
and the router diagram above. Your goal will be to configure the router as quickly as possible
without errors. You will also configure the IP settings for one of the corresponding Ethernet
attached workstations.
Tools / Preparation:
Prior to starting this lab you should have the equipment for the standard 5-router lab available.
The NVRAM of the router you will be configuring should be erased. Before beginning the lab,
the instructor or lab assistant should login to each router, enter the privileged EXEC mode,
issue the erase startup-config command, and then issue the reload command. This
will force the routers to come up with a blank configuration. The IP configuration for the
associated workstation should also be changed so that it is incorrect. The answer section
includes examples of the detailed command sets that the students will have to master. The
instructor will review the router configuration when finished.
Worksheet
Step 1 - Review the physical connections on the standard lab setup.
Review the standard semester 5-lab diagram in the overview section of this lab and check all
physical devices, cables and connections of the lab setup to familiarize yourself with them.
Step 2 - Console into the router.
Verify that you have a good console connection and that HyperTerminal is configured
properly. The router should be booted with no startup configuration file in NVRAM.

Step 3 - Identify IP address information.
1. Fill in the table with IP interface information from the diagram for each of the five routers.

* Note: Clock rate must be set on the DCE end (S0) of the WAN link between routers.
Step 4 - Configure the router via the console connection.
1. Select a router and time yourself. Configure the following information for each router: Host
name, passwords, IP addresses for interfaces, routing protocol and associated network
numbers, IP host lookup table. Repeat with other routers.
Note: make sure you copy the running configuration to the startup configuration when you are
finished or you will lose the configuration upon next reboot.
Step 5 - Configure the workstation IP settings using the Control Panel / Network icon.
1. Configure the IP address, subnet mask and default gateway to be compatible with the
router.

Step 6 - Test your configuration with ping and telnet.
1. From the PC DOS prompt, use the ping and telnet commands to test your configuration.
Listed below are the outputs from the show running-config command for all five router in
the standard lab setup. If you have problems configuring a particular router refer to these for
help. Answers may vary depending on the router model number and exact configuration of
your lab setup.

Lab 8.2.1 Individual router config. - Answers
Students should be able to repetitively configure the
practice lab. At the start of this section you should log
onto each router in the enable exec mode and issue the
erase startup-config command, them issue the reload
command. This will force the routers to come up with a
blank configuration and allow the students to practice
the skills they will need to pass the semester two final
lab exam. Below are the detailed command sets that the
students will have to master. All commands are provided
for router Lab-A. A table of configuration settings for
the other routers follows these instructions.
