To begin we need to download the software – a simple Google search takes us to http://www.gns3.net/download to be able to download the software. It is available for Windows, MacOS and Linux. For this demonstration we will install the Windows version.
The biggest trick to getting GNS3 running is also downloading the IOS image needed for the simulator to work. You can download IOS or JunOS images from Cisco or Juniper’s website. Some support platforms are the Cisco 2600 and 3600 series routers.
Check out this video as I run through the entire process and getting GNS3 installing and running on my laptop.
In our next video we will be build out our virtual network a bit more to include a third routing and start talking about routing.
