Hm not sure what happened. I opened a question and got a nice answer from jpelizaeus which assumed I wanted to set up a microcloud, but I was only for the network part, an easy way to set up an OVN bridge. Maybe MicroOVN is inseparable from microcloud? Anyway I am pretty sure I did not mark the answer as a solution (or I read the answer in a different before) and the discussion closed automatically the next day.
