What happens if you make the cost on the LEGATO link 2 instead of 1?
The cost on my Multinet links are all set to 2. Since your current LEGATO cost is 1, the
total cost of that path to area 59 is 3. The exactly equals the cost on you UNA circuit.
In the case of a tie on cost, DECnet picks the router with the lowest numerical address,
hence LEGATO wins.
But if you up the IP-0-0 cost to 2, the total would become 4 and the UNA would win.

? - Total areas: 17-
Notice the number of areas that MIM now decided should go over IP-0-0,
which is the link to LEGATO. Since I set the cost for that link to 1,
while ethernet is at 3, it is rather favored. Not sure it really makes
sense to route packets to area 59 that way, since going over ethernet, I
would have a direct ptp to area 59 through a Cisco router sitting right
next to MIM, but that then becomes a question of what the cost of the
link between 1.1023 and area 59 is set to.
