Because pathalias computes routes based on the end-to-end costs of
a route.  Pathalias is routing through the well connected site, as
its costs to the rest of the known world are less than your other
connections.

Declare the cost to this site obscenely high.

This is what its doing.

Nothing wrong, but I don't find it necessary to cat everything into one 
file.  I'd just run something like ``pathalias u.* d.* local.*'' and let
shell wildcarding expand the map filenames into command line arguments
for pathalias.
