What is GNS3 and how it works? GNS3 (Graphical Network Simulator) that allows the emulation of complex network topologies via a program called Dynamips on a Linux or Windows based computer. Everyone can download and use it because it is a free open source software. However, GNS3 uses real Cisco IOS images to mimic a network, you need to obtain the images from Cisco and it does not come for free. GNS3 is a graphical network simulator that allows you to design complex network topologies. You may run simulations or configure devices ranging from simple workstations to powerful Cisco routers. It is based on Dynamips, Pemu/Qemu and Dynagen.
