For network engineers, architects, and students pursuing certifications like CCNA, CCNP, or CCIE, simulation is a crucial part of learning. Physical hardware is expensive, space-consuming, and not always accessible. This is where Cisco IOU (IOS on UNIX) images shine.
Although limited to L2, version 15.2d includes support for basic and LISP control plane elements, making it useful for prototyping Cisco's Software-Defined Access (SDA) underlay. Fix the permissions using the EVE-NG CLI command:
Correct the file permissions via the EVE-NG CLI using the mandatory command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution.
