Ah OK I missread, although in the case the physical interfaces is up
to the carriers switch but the far end is down, BFD should keep the
OP's interface down.

OK so assuming BFD is detecting the link as recovered then I think the
only options are dampening or increasing the carrier delay / hold
time.
