· friend i m ccna and looking for ccnp and ccip for da days i started ccna study i m using cisco packet tracer but facing a lot problem while config OSPF over frame relay there are lots of frame relay and ospf commands are not working on packet tracer so i found about GNS3 and according through GNS3 user it is best for CCNP students after. from Cisco perspective we are not allowed to use image on GNS3. there is no demo of IOS. no official word from Cisco regarding using image in gns3. some users argue that u could use image from real device u owned; I think this might be a grey area; what about GNS forum or gns3 people, do they mention anything about getting images? 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 , there is a way to run a second category of switches and routers. These are classified as Routing and Switching virtual machines (or R+Svms) for short.
In this video I show you how to download Cisco IOS images (Cisco VIRL images) to run IOSv and IOSvL2 in your GNS3 topologies. I also show you how to add Docker containers to your network. Cisco VIRL has fantastic images which you can download such as: Cisco ASAv - Virtual Cisco ASA Firewall - Cisco IOSv - Virtual Cisco Router - Cisco IOSvL2. Step 9. Select the Router image that you downloaded to your computer and click the Open button. Step Click the Yes button to extract the compressed GNS3 Cisco IOS image. Step Wait while the router image is decompressing. Step After adding Router, click Next to continue. Step With GNS3 you actually need the IOS's! No need for that with Packet Tracer. The only thing with Packet Tracer is you have to be in Cisco Network Academy to get a legal copy of it! Also with GNS3 you do not have to much you can do with Switches.
Download Cisco IOS images and use in GNS3 GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.

We do not suggest or encourage the use of unauthorized sources/websites to download them. Instead, we recommend using authorized learning solutions to help you practice and prepare for your exams. You might consider taking a look at Cisco Learning Labs, which are guided virtual practice labs powered by real Cisco IOS. Cisco Learning Labs are.
