Ubiquity<->Mzima routing loop

No, a true routing loop will transit several hops and end back up at the same routers. A bouncing route between 2 routers is usually a directly connected route on an interface that goes down thereby "pulling" the route with out a nail down route it will send unkown route back out its default gateway.

Out of curiosity, what's the biggest loop anybody's come across? I see
plenty of "two adjacent routers pointing at each other", and the occasional
3-router loop and the rare 4-router loop.
