If not able to download copy and save below python code with same filename. Download the IOU licence key generator named CiscoIOUKeygen3f.py from here.

Now, we need to add the IOU licence under the EVE-NG to run the IOU/IOL image.Ĩ. On cli, change the directory using below command and check the images are uploaded cd ls -l opt/unetlab/wrappers/unl_wrapper -a EVE-NG:~#Ħ. Further, open cli access to EVE-NG using tool like Putty and fix the permission of the images you just have uploaded in order for them to work using cli command as below. Now upload the IOU/IOL images to EVE-NG under location /opt/unetlab/addons/iol/bin/. I also show you how to add Docker containers to your network.4. How do you build Cisco networks in GNS3? In this video I show you how to download Cisco IOS images (Cisco VIRL images) to run IOSv and IOSvL2 in your GNS3 topologies.
