  It bugs me, although I can't point at an actual problem that it causes,
that the routing node for area 1 is seen as CTAKAH, rather than MIM.   Since
CTAKAH is not actually local to Uppsula (I think that's where MIM is) but is
rather at the other end of yet another bridge, this means that any traffic
for area one, no matter what its ultimate destination, has to make an extra
round trip to Russia.   

  This happens because when there are multiple routing nodes for the same
area, DECnet uses the one with the highest address.   The obvious solution
would be for Johnny to renumber MIM as, say, 1.1023.

Or make CTAKAH a circuit router since that is all it really does.
The "loops" in the Hecnet topology ought to be avoided but running area
routers where a circuit router would suffice is second on my list of
things I'd prefer to avoid.
