Although the image is provided as a VMDK, it is not a standalone VMware appliance. It must be loaded via a platform (like GNS3 or EVE-NG) that can instantiate the QEMU hypervisor. This image cannot be directly powered on in VMware Workstation without further configuration to emulate a router.

Cisco IOS (Internetwork Operating System) is a family of network operating systems used by Cisco routers and switches. It's known for its reliability, scalability, and feature-rich functionality.
