Krist -

Please open a case w/ cumulus support, or if you have, feel free to point
me at it.  I'd like to track this issue there.

I would not expect Cumulus Quagga to work with unnumbered upstream, since
it's not in there.  I have some strategies for you to try out but it might
be best to take this off list for discussion.
