Just sent mail to the case engineer :-)

That's exactly the scenario - two Sup720 boxes linked together with
a "long range Gbit" solution from another carrier, which they implement
via EoMPLS.  So depending on the actual error modes on the path, it's
well possible that we'll still see a link on both sides, but still 
have no end-to-end connectivity.

As we don't have BFD today, we can live without it for some more time,
of course.
