💡 : Remember, this is a pure router image. It lacks switching features like VLANs and VTP. For switching, you must pair it with a dedicated L2 image.
EVE-NG is currently one of the most popular platforms for hosting IOU images. Users upload the i86bi-linux-l3-adventerprisek9-15.4.2t.bin file to a specific directory within the EVE-NG virtual machine ( /opt/unetlab/addons/iol/bin/ ). After adjusting the file permissions and generating a valid license file ( iourc ), the image becomes available as a drag-and-drop node within the web-based topology designer.

Most "License Error" messages are due to a missing or incorrectly formatted iourc file, which contains the hostname-based key for your specific virtual machine. i86bi-linux-l3-adventerprisek9-15.4.2t.bin

Upload the file to /opt/unetlab/addons/iol/bin/ using WinSCP, then fix permissions using the EVE-NG CLI command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions . 4. Troubleshooting Common Errors
Similar to EVE-NG, PNETLab is a lab simulation platform that natively handles IOL/IOU binaries, allowing engineers to build multi-tenant, cloud-accessible network topologies for training purposes. Important Considerations: Licensing and Legal Compliance EVE-NG is currently one of the most popular

GB per router), IOU images are just lightweight binaries executing natively within a UNIX environment. A Cisco IOU router can often boot with as little as MB of RAM, allowing you to run complex, -node topologies on a standard laptop. 2. Advanced Protocol Support
