In this lab, you will learn about the configuration register on Cisco routers. You will review the bits in the register, modify the register values on Cisco 2500 and 3600 Series Routers, and configure the routers to boot a Cisco IOS® image from different sources.

This lab will focus on how to set the configuration register bits 0 to 3 to different values, and how to boot the router from the different sources using the configuration register setting. These steps will allow you to practice some basic memory management commands on routers.


This lab has the following objectives:

The above commands are not all available on all of the routers in the simulation. Use the ? command to determine the commands available on each router.


Click on the Configuration Lab icon to the right to open the interactive simulation environment window in a new browser.

To enter commands, activate the simulation environment Telnet window by clicking in it.

To see a list of supported commands at each step of the exercise, you can enter the ? command (press the question mark at the prompt). If you need more help, check the tutorial to review the configuration instructions.
