GNS3 2.1 Install and configuration on Windows 10 (Part 1): Components and software requirements

This video explains and demonstrates how to install the GNS3 Windows GUI on a Windows 10 PC. This is one of a series of videos showing you how to get started using GNS3 on Windows.


This is one of multiple videos showing you how to download, install and configure GNS3 version 2.1 on a Windows 10 PC.

When you first start out with GNS3 it can be quite confusing and even overwhelming to know what to do because there are many components and technologies that you can leverage within GNS3.

In brief, there are two main components that you need to be aware of. The first component is the GNS3 GUI or GNS3 Graphical User Interface. This is a Windows executable that you install on your Windows computer.

The second main component is the GNS3 VM or GNS3 Virtual Machine. This is a Virtual Machine that you run within a hypervisor such as a VirtualBox VMware Workstation or VMware Player.

In some cases, you don’t have to use the GNS3 VM. You only need the GNS3 Graphical User Interface. But for most implementations and for the best use of GNS3, it’s recommended that you use both the GNS3 GUI as well as the GNS3 VM.

In addition,you’re going to need the operating systems of devices.

So in other words, if you want to run a Cisco IOS router, you need the Cisco IOS software.

If you’re going to run an Arista switch, you need the Arista operating system or if you want to run a Juniper firewall, you’ll need the Juniper operating system. So whenever you want to add networking vendors device to your GNS3 topologies, you’ll need to provide the operating system for that device and you’ll need to download the operating system from the vendor’s
website or as an example, copy it from a physical router or switch.

And neither I and nor GNS3 can legally provide you with a Cisco IOS images. You have to provide your own images. that is a requirement for using GNS3.

I would love to give you IOS images but neither I or GNS3, due to legal requirements, are able to provide IOS images to you, you need to provide your own.

In these series of videos I’m going to show you firstly, how to install the GNS3 GUI and get a basic network working using the GNS3 GUI. And then in subsequent videos I’ll show you how to download and integrate the GNS3 VM with the GNS3 GUI and how to run devices such as Cisco VIRL IOSv and IOSv Layer 2 on the GNS VM.
