The first thing to do after installing the GNS3 network simulator program is to add a Cisco Router or Switch IOS image.If you don't have IOS images, you can download the related files from here.
You can install this simulator software on Windows, Linux and macOS operating systems.You can make more professional network designs on GNS3 by using IOS images of real Cisco network devices.Let's examine how to add and run a router IOS image to GNS3.
After installing GNS3, run the program and select 'Run only legacy IOS on my computer' in the Setup Wizard window.
Leave the default settings in the 'Local Server Configuration' window and click the 'Next' button.
Click the 'Finish' button in the Summary window.
C isco IOS images for Dynamips. GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images. In the new GNS3 1.4, there is a way to run a second category of switches and routers. If your goal is to run GNS3, then you need to get the IOS images in an appropriate way. But, if you're trying to work with a lab setup, consider getting the actual physical gear. There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional. And they're available inexpensively or even free.

Type the project name and click the 'OK' button. Select where you want to register your project by clicking the 'Browse' button.
In the 'New appliance template' window, select 'Add an IOS Router using a real IOS image (supported by Dynamips)' option and click the 'OK' button to continue the IOS add steps.
Click the Browse button to specify the location of the image file.
Click the Yes button to extract the compressed IOS image.
Wait while the router image is decompressed.
After adding iOS, continue by clicking 'Next' button.
After configuring the name and platform of the version of the Cisco Router you added, click 'Next' button.
In the Network Adapters window, you can choose which slots you want to add to the Router.
To add the FastEthernet interface to the Router 7200 as in the image below, select 'C7200-IO-FE' in Slot0 and click the 'Next' button.
You must set an Idle-PC value for the router.This value may vary depending on the performance of your computer.

In order to perform CCNA and CCNP hands-on lab exercises, either you need the physical devices or a simulator. Since arranging physical devices, such as Cisco routers and switches is probably not possible for everyone. Fortunately, there are various simulators such as Cisco Packet Tracer and GNS3 that you can use to perform CCNA/CCNP and other hands-on lab exercises. In this post, you will get the direct links to download GNS3 IOS images for Cisco routers, ASA, switches, and even for Juniper routers.
One of the great features of GNS3 simulator is that it allows you to perform real-life hands-on lab exercises. However, you need to download IOS images for GNS3 before you can perform the hands-on lab exercises.
