Dynamips and Dynagen are basically vmware for Cisco IOS. This software runs actual IOS images for several cisco platforms including the 7200 series. That’s right "actual" ios images. This is not a flash simulator that is missing half of the commands. When studying for CCNA, CCNP and CCIE exams, this software is a must. I hope you enjoy the video tutorial.
Started in August of 2005 by Christophe Fillot, Dynamips is a Linux and Windows based application that is used to emulate the hardware of the Cisco 7200 and 3600 series routing platforms. Unlike traditional router “simulators" Dynamips allows you to boot real Cisco IOS software images and build complex network topologies to test the functionality of IOS on your desktop PC. As of November 2006 Dynamips currently supports Ethernet, Serial, ATM, and POS interfaces for the 7200 series routers and Ethernet, Serial, and Etherswitch modules for the 3600 series routers. Best of all Dynamips is open-source and free to download!
