What is a Router Simulator

Router Simulators are a great way to create and test new network topologies without the expense of lots of hardware. Many people use router simulators to help them practice and study for upcoming certification tests and many people are able to pass these certifications because of the convenience of a router simulator.

GNS3 is one such router simulator. Its is an open source project that is available for download to run on your Mac, Windows or Linux computer. With GNS3 you can simulate Cisco routers, switches, PIX firewalls and ASA firewalls. You can also simulate Juniper devices and connect your virtual network to a real live network.
