Product Information
What is Gns3?
GNS3 is a graphical network simulator capable of emulating complex networks.
To deliver comprehensive and accurate simulations, GNS3 works closely with the following:
Dynamips, a Cisco IOS emulator.
Qemu, a versatile open-source machine emulator and virtualizer.
VirtualBox, a free and powerful virtualization software. GNS3 serves as an excellent supplementary tool for network engineers, administrators, and individuals preparing for certifications like Cisco CCNA, CCNP, CCIP, and CCIE, as well as Juniper JNCIA, JNCIS, and JNCIE, offering a realistic lab environment.
It can also be used to explore the functionalities of Cisco IOS and Juniper JunOS or to verify configurations before deploying them on actual routers.
Thanks to its integration with VirtualBox, even system engineers and administrators can leverage GNS3 for studying Redhat (RHCE, RHCT), Microsoft (MSCE, MSCA), Novell (CLP), and various other vendor certifications.
This project is an open-source, free program compatible with multiple operating systems, including Windows, Linux, and macOS X.
