Always pull the foundation software directly via official channels.
Network engineers frequently search for a solution to bypass official download restrictions, fix bugs in older image sets, or resolve deployment corruption. However, handling modified files or seeking unofficial downloads carries notable performance, operational, and legal risks. The Architecture of the Refplat ISO cisco cml refplat iso download patched
Every network node simulated within a CML topology runs as an individual virtual machine. The is a consolidated software repository containing:

You can find it on the same download page by selecting the 2.8.0 Free Tier option. The Free Tier has a more limited Refplat ISO, but it's a fantastic way to learn the platform without a paid subscription.
Cisco Modeling Labs (CML) relies heavily on these Refplat ISO packages to provide the necessary virtual machine images (such as IOSv, IOSvL2, NX-OS, and ASA) for network topology simulations. Karlo Bobiles
CML is updated frequently to support new hardware platforms and software features. Using a static, patched version locks you out of these updates and official support from Cisco.
