GNS3 is a free, open-source tool that provides emulation of network hardware (such as Cisco routers and firewalls), so that customers can practice, configure, and troubleshoot network scenarios all in a virtual environment running right on their Windows, Mac OSX or Linux computers. Multiple network topologies can be saved, paused and/or resumed on the fly so that the learner can practice at the convenience of their own schedule. GNS3 provides the emulation of the physical devices, and the user provides the OS image for the version/vendor of the software they want to practice on.
