Step 5: Install GNS3 GUI(Optional)

If you have installed GNS3 server without the GUI, you can install the GUI on your local machine. Download the appropriate package for your operating system from the GNS3 website.

To install the GNS3 GUI, follow the instructions given in the package.

Step 6: Launch GNS3
