I think the problem he’s referring to is the default gateway programmed in the radio.

You shouldn’t have a stranded backhaul in a meshed network running OSPF/internal BGP. If the link is actually hardware down or even has hardware up but non-functional, the routing table should still reflect the routes that are up (i.e. the ones where OSPF/BGP continues to communicate).
