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. GNS3 is getting a bit dated, due to its ability to only support really old Cisco IOS images. Check out Cisco's official tool, VIRL. I would put 12GB of RAM into your machine if you want to do any kind of serious simulation.
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.
