: Full support for BGP, OSPF, EIGRP, and ISIS.
Linux requires explicit execution privileges to run binaries. After uploading, you must log into your EVE-NG or Linux CLI via SSH and apply the correct permissions: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution.
Because IOL runs as a native process rather than a virtualized machine, it requires significantly less RAM and CPU, allowing users to run dozens of routers on a modest laptop.
You will need a valid iourc license file for IOL images to run properly. Without this, the IOL process will terminate.
