Hi Dag, Thank you for guiding me, i know it's a weird use case and probably would never be required in a production environment. I will definitely try to make a dummy interface and give it to the guest network target bridge. I know it would be out of the scope of this email trail for you to explain me tagged and untagged networking in L2 and L3 networks, but I would search around the internet and ping this thread if I'm again stuck at some specific issue after I reach my university's lab. Appreciate your help.
