GNS3 Supported Cisco Router IOS Images Download

GNS3 is more specific and professional than Cisco Packet Tracer. There is no need to add any Cisco devices to the Packet Tracer, but it is absolutely necessary to download and add the Cisco IOS for GNS3.

You need to use GNS3 to use the actual Router and Switch IOS images. With this software, you can emulate a Cisco Router/Switch and prepare for Cisco exams in a more professional way.

You can download and use the most suitable Cisco images to avoid problems when using the network simulator. You can also check out this article to install GNS3 on your computer.

You also need to configure Minimum RAM when adding a Cisco Router or Switch images to the program.

If you set a value that is greater than the minimum RAM requirement, you will put more load on your computer’s processor and experience performance issues.

If you have a powerful PC, you can also set a higher RAM value for Cisco Routers.

When adding a Router to the simulator software, an IDLE-PC value is also determined. The IDLE-PC value is determined by the hardware specifications of your computer so that the routers you add can work more efficiently.

The running IOS images you can use on GNS3 are the c3640, c3660, c3725, c3745, and c7200 versions.

Here are a few additional Cisco Router images. For example, if you use a c1700 series Router, it will be insufficient because it does not support some features when you create a more advanced network topology.
