It seems that there is no fast spanning tree in Open vSwitch[1].

I'm wondering if I need spanning tree at the first place.

Looking at a web article “Setting Up Overlays on Open vSwitch”[2], the
author setup a full mesh configuration but does not use spanning-tree to
prevent loop.

Maybe the solution is in the created flows, which looks like magical
incantation to me?

Regards.
