Hi, thank you for your answers. I'm added in line the outputs:

But the other command gave me: error: garbage option.

I should also connect the compute nodes to an OVSwitch located in another VM to build up the data network. Also because in the ODL GUI I can't see any link that connects OVS. (How to eventually connect mininet?)
