Since GNS3 is not a simulator but a typical router emulator that uses original IOS images of the routers that are developed by Cisco, it is important for you to understand how to mount the images on the GNS3 interface so that you can use them to create and configure virtual routers and topologies in the GNS3 console. Unlike router simulators like Packet Tracer that provides the output result on the basis of the programmed reaction as per user interaction, a router emulator like GNS3 always provides the most accurate and real-time outputs to the commands that the users type within the console. The reason behind this accuracy in the results is because it is the original IOS image that works within the virtual routers. Such IOS images are the backup files from the physical routers, and therefore they respond to the users’ inputs exactly the way the physical routers do. Mounting the IOS images is a simple task, however you might need to analyze and look for the correct image before you mount it to the GNS3 application. Since GNS3 is a dump software, you must have good understanding of the Cisco routers and switches series, their IOS images, and how to configure the routers.
