Re: OSPF Backhauls Hmm, if I may - what exactly is being asked?
I think he is asking about the ubnt bridges between mikrotik routers and OSPF if a link goes down, and the ubnt loses its ability to communicate with its default gateway you can't access them out of their subnet after OSPF re routes around the problem.

We used to do radio management like the following diagram.
Blue is a VLAN which we are using to route between the two POPs, and red is a VLAN used for device management at the POP on the left.
If the router at the remote side had issues, you were at least able to confirm it was the router, and not the link in the middle.
We would run OSPF over the blue VLAN, but red was basically an access VLAN solely for management devices.
