Select Image Name and enter the name of the image you are using: The Cisco Feature Navigator is opened in your default web browser. Click the 'Check for minimum and maximum RAM requirement' option:

It is important that you check your Router's minimum memory requirements using the Cisco website. Click 'Next' :Ī Default RAM setting is displayed. Confirm the Platform selection, and configure the router Name. The directory where the decompressed image is stored is displayed. This is recommended for a better user experience. GNS3 can decompress IOS images to allow for quicker booting of routers in your GNS3 topologies. The GNS3 team are unable to legally provide Cisco IOS images to anyone. Others do not, and you are required to provide your own images. Some vendors provide images of their systems for free. On the next screen, click 'Browse' to import a supported IOS image:īrowse to the folder where you have stored your Cisco IOS images, select the image, and click 'Open': (the option to run the image via the GNS3 VM isn’t greyed out in the above picture, since the GNS3 VM had previously been set up on this PC)

You’ll be prompted which server you’d like to run the image with, but everything except 'Run the IOS router on my local computer' should be greyed out. In the preferences menu, select 'IOS Routers and New', to begin the process of importing an image. In the GNS3 GUI, click Edit > Preferences, to open the preferences menu. However, this article will discuss adding and configuring a supported IOS image manually, as the articles here and here discuss appliance templates, and using the Import Appliance Wizard to automate installation of images/VMs/docker containers. The appropriate appliance templates for the devices you wish to use, are available in the GNS3 Marketplace. With recent releases of GNS3, devices are typically installed using the Import Appliance wizard (File->Import Appliance).

The basic CLI commands for all of them are the same, which simplifies Cisco device management. Almost all Cisco devices use Cisco IOS to operate and Cisco CLI to be managed.
