What version of code did you test this on?
I attempted to use the neighbor priority to influence election ( I did both
neighbors on the Hub as 0 ) yet one of the neighbors still became a BDR and
the other became a DR. I had also put the priority 1 on the spokes neighbor
statement pointing back to the Hub, yet it was a DROTHER.
The only way I could get it to work correctly was to use the OSPF priority
statement under the interface.
Thanks
Larry

As far as I know, the priority keyword in neighbor statement means the
neighbor's priority. It is recommended to set on NBMA networks to influence
DR election.
For example if the the router has config like
int s 0
encapsulation frame-relay ietf
ip address 172.16.100.1 255.255.255.252
ip ospf priority 0
router ospf 1
neighbor 172.16.100.2 priority 100
Then this router does not try to be DR or BDR but consider the neighbor as
DR, this simplifies and determines the DR/BDR selection. It works this way,
I have tried this.
In fact, I don't know if the priority in neighbor statement takes precedence
over the priority in hello packets.
