You can download GNS3 from below location (GNU GPL license) Sad… I wish some how we could run Switching also in GNS3… You still need to depend Cisco Packet Tracer for CCNA CCNP Switching part and real Cisco Switches for CCIE Switching part. Only trouble is GNS3 cannot run Switching part. You can run Cisco Router IOS on GNS3 to practice CCNA, CCNP and CCIE routing lessons. But Boson and packet tracer are half baked and you cannot run all the Cisco IOS commands in these software. I remember how much I struggled using Boson Cisco CCNA/CCNP software and Cisco Packet Tracer software to learn CCNA topics. Jeremy Grossmann, Benjamin Marsili, Claire Goudjil and Alexey Eromenko(all french men) are the main brains behind GNS3. Aziz said, GNS3 is a great front end for Dynamips.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers.

GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.

Dynagen, a text-based front-end for Dynamips.

Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.

To allow complete simulations, GNS3 is strongly linked with : GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them.
