Here's a dump of the messages to the NOX controller showing the loop happening.

Hi all,

We have a setup here of three OpenFlow switches in a ring: mvm-ofroot,
mvm-of1 and mvm-of2

It seems that NOX doesn't do any type of spanning tree when flooding
packets. I have an arp packet coming in to ofroot from the "outside".
ofroot then seems to flood to of1 and of2. These switches then dutifully
try flooding the packet themselves. We end up with ARPs floating around
in a loop :-(

Are you guys aware of this issue? Is there a planned fix for this?

Thanks,
Glen
