Virtual PC Simulator. RetroArch is a frontend for emulators, game engines and media players. A collection of Labs built for GNS3. About this book GNS3 is an open-source Graphical Network Simulator used extensively by networking professionals to simulate networking devices such as Cisco, Juniper and Vyatta routers, along with Virtual PCs. GNS3 Network Simulation Guide gives you all the information you need to run a successful GNS3 simulation. GNS3 a Network Simulator As the heading suggests, GNS3 is a virtual network simulator. We are able to build, design and test topologies using the software. GNS3 allows us to rapidly prototype various different network configurations, concepts and applications with a very simple drag and drop functionality.

Real World Application

GNS3 is commonly used as a training tool for those whom are interested in learning how to configure Cisco equipment or even those whom are seeking to achieve Cisco Career certifications. GNS3 is used by all levels of Cisco students for training from the CCNA all the way up to the CCIE Certification.

GNS3 was originally intended to be a training tool but has another great use in the real world which is config verification and command verification. If you’re wondering how to setup a feature you have in mind but do not have a router on hand and cannot do it on production routers then fire up GNS3 and you’re free to configure till your fingers are blue.
