Scp it to your eve-ng machine with ip 10.3.0.* (remember the credentials root:student) on path **/opt/unetlab/addons/iol/bin**. | + | Go to eve-ng webui and create a new node, using 'Cisco IOL' template.

| - | Copy the SRED license with header to /opt/unetlab/addons/iol/bin/iourc file. In the end, you will need to have something like this: | + | |
