GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap. Feel free to download them and use them for your Cisco certifications studies. Here I am listing all the working versions of Cisco IOS which I have tested with the latest version of GNS3. (Please remember to honor your company's IT policies before installing new software!)
