Nick,
Since all of these OSPF routes are in the same area. Say for example area 0
then you will see the advertising router as the DR for the LAN segment
connecting them, correct. Adjusting the distance for the specific neighbor
wont have an effect on. If the LAN was in a different area that would be a
different story.
Without knowing the actual wording of the question etc. You could adjust the
cost on a per neighbor basis if these were point-to-multipoint OSPF network
types This would give you the desired preferred routing, assuming this
command is allowed.
