As well, it an be used in the ISIS routing process for exactly the same
reason, however, be aware that ISIS will award the higher priority the
DR position, there is no BDR.

Hi Bruce,

the neighbor (priority) command in OSPF is used to assign appropriate
cost
to incoming routing updates on a hub and spoke topology where the two
spokes
are reachable via different speed L2 circuits. It only applies to
point-to-multipoint non-broadcast network types and it allows the hub
router to accurately determine the least cost to path to destination
networks beyond the spokes.

this link may help you undersand this feature.
