Since we are running GNS3 on Ubuntu, we shouldn’t worry about the support of IOS/IOU/KVM images. If you are not using a GNS3 VM or GNS3 server, the devices will run on your local OS commonly put as the local server. In such a situation, a remote server would be of great help. At times, you might need to create an intricate network that will consume your laptop’s memory. The GNS3 Server runs your devices on a remote machine saving your PC resources. Therefore, if you are running GNS3 GUI version 2.2.3 and you want to use GNS3 VM, then it should also be version 2.2.3. Also, the GNS3 GUI application version should be the same as the GNS3 VM version for you to configure them correctly. It runs on the VMware virtualization software. The GNS3 VM is a utility mainly for Windows and OSX users who want to run IOS/IOU/KVM images. It’s a graphical user interface with several devices to simulate a network. We will create or network topologies and labs on the GNS3 application. Therefore, before getting down to the download and installation process, let’s look at some of the components we will need – GNS3 application and GNS3 VM or GNS3 Server. Getting started with GNS3ĭespite being one of the best network simulation software in the market, GNS3 comes with several complexities. It has opened a whole new world in the field of networking – Network Automation using Python and Ansible scripts. GNS3 version 2.0 and newer releases support the Docker feature. These include CISCO, Juniper, Aruba, Cumulus, Arista, and many more. GNS3 is also a multi-vendor support application enabling you to create labs using devices from several vendors. It is open-source software, and so you can find the complete source code in GitHub. Having grasped that, we can now look at other exciting features of GNS3. When you use a router in GNS3, you are running the real device operating system. A Network Simulator, on the other hand, is software that virtualizes your hardware enabling it to support the operating system of different networking devices.
