GNS3 is a network emulation tool that allows network engineers to simulate complex network topologies in a virtual environment. It provides a graphical user interface (GUI) that enables users to drag and drop network devices such as routers, switches, and firewalls, and then connect them together to create a virtual network.

With GNS3, network engineers can test and troubleshoot network configurations without the need for physical network equipment. This makes it a powerful tool for network engineers who want to test and validate network designs before implementing them in a production environment.

GNS3 can run on a variety of operating systems, including Windows, Linux, and macOS. It supports a wide range of network devices, including Cisco routers and switches, Juniper routers, and more. GNS3 can also be used with virtual machines, making it possible to emulate entire networks, including servers and client machines.

GNS3 is an open-source tool, which means that it is free to use and can be customized to suit specific needs. It has an active community of users who contribute to the development of the tool, providing support and sharing tips and tricks.
