GNS3 Tutorial - PDF Documentation
From the developers: " GNS3 is a graphical network simulator that allows simulation of complex networks.
To allow complete simulations, GNS3 is strongly linked with :
- Dynamips, the core program that allows Cisco IOS emulation.
- Dynagen, a text-based front-end for Dynamips.
- Qemu, a generic and open source machine emulator and virtualizer.
GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE.
It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers.
This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X."
Here is a FREE excellent document in PDF format explaining how to use GNS3 - highly recommended for beginners.
