How to Download Cisco IOU/IOL Images
Cisco IOU/IOL images are L2/L3 images of switches and routers that have the same features and functions as real devices. They are mainly used for CCIE routing and switching practice, but they can also be used for other purposes.
Since Cisco IOU/IOL images are internal IOS versions, they are only available for Cisco employees or authorized customers. Therefore, you cannot download them from official sources. However, there are some unofficial sources where you can find them legally. For example, you can join some online communities or forums where people share their experiences and resources about network simulation. You can also search for some torrent sites or file-sharing platforms where people upload their own copies of Cisco IOU/IOL images.
Before you download any Cisco IOU/IOL image, make sure that it is compatible with EVE-NG emulator. EVE-NG supports most of the Cisco IOU/IOL images, but some of them might not work properly or cause errors. Here are some of the recommended images for EVE-NG:
