I posted this once before, during the latest Great Mysterious News Blackout.
Somebody should investigate those things. Anyway, I never saw it, so here goes
again...

A while back I posted a message asking for recommendations about DECnet area
numbering. I received a number of very helpful replies, totalling somewhere in
the range of 120 kbytes.
One message, from Phil DeMar of Fermilab, stood out as a most valuable piece
of work - a rather large memo entitled "MANAGING AREA NUMBERS IN MULTI-
ORGANIZATIONAL DECNET NETWORKS". It outlines the measures taken by SPAN and
HEPnet, including, among other things, a recommended numbering scheme, and a
DECnet techique called "area filtering", for controlling the propagation of
area routing information.
The upshot: DON'T USE AREA 1 - USE A NUMBER ABOVE 46. The technique, an
admitted kludge necessitated by DECnet, declares areas above the arbitrary
value of 46 as local, to do with as you want; the others are global.
I would recommend that document to anyone involved DECnet management. It
runs about 46 kbytes, so I hesitate to post it to the whole group. If you want
a copy, contact either Phil DeMar at DEMAR@FNALE.bitnet, or myself.
