Yeah, I was wondering if there could be primaries after the
secondaries.  I'm pretty unfamiliar with this code (first looked at it
last week) and still don't have a handle on how the primaries
interact with the secondaries in the route lookup.  Which means it's
not clear to me why this was failing to begin with. :)

Your patch works for all of the cases I've been testing with so it
looks good to go from here.
