I have a friend who is currently trying to obtain his Cisco CCNA certification. In an effort to assist him in his preparation as well as to ensure that he can actually carry out CCNA level tasks I wrote up a quick CCNA lab that utilizes Dynamips / Dynagen. The lab itself will test your ability to configure basic router settings that a CCNA could be expected to perform. The lab itself is not very in-depth and is only one of many labs I have written. What is Dynamips / Dynagen dynamips is a Cisco hardware emulator that runs on both Linux and Windows (with winpcap). The emulator can load up the actual IOS .bin files and allows you to emulate the following router platforms: 7200, 3600, 2600 series routers. It also has built in functionality to emulate Ethernet switches and frame relay switches. Dynagen is a python front end that allows you to quickly load up a lab into the dynamips hypervisor. My practice labs make use of the dynagen front end for dynamips.

You will need to edit the path: /home/brian/dynamips/dynagen/images/ to the path and filename of your extracted IOS bin file. I wrote the .net file for use with a Linux system, but it can easily be adapted for a windows system as well. You will also need to download an IP Base or IP Plus IOS image for a 2691 and a 3640. You can do this via your Cisco CCO account. Lab: http://www.jbclark.org/ccna-lab-v1-for-dynamips.zip If you want the solution configurations for the lab please PM me.
