GNS3 is software that simulates complex networks while being as close as possible to the way real networks do, all this without having special network hardware such as routers and switches. It can also be used for trial features or to check configurations that need to be used later on real devices.
Build, Design and Test your network in a risk-free virtual environment and access the largest network community to help. Whether you are studying for your first network exam or building a nationwide telecommunications network, GNS3 offers an easy way to design and build networks of any size without the need for hardware. And the best part is it’s free!
GNS3 allows you to run a small topology consisting of only a few devices on your laptop, to devices that have multiple devices that are hosted on multiple servers or even hosted in the cloud.
This is a client part of GNS3 and is a graphical user interface (GUI). You install all-in-one software on your local PC (Windows, MAC, Linux) and create your topology using this software.
GNS3 is perhaps the most well-known platform used for learning and teaching. GNS3 has for years been used by students and network engineers to help practice and prepare for vendor certification exams such as the Cisco CCNA exam.
