Then, I think that in the real world the best solution is configure the priority at the spokes interfaces...
About the DR 0.0.0.0 it4s is a misterious question... I can obtain it using networks point-to-point or point-to-multipoint therefore no DR election will occur... But there are any option where I can do it without changing the OSPF network type?

From a design standpoint, I'd configure ospf priority 0 on the spokes and
neighbor statements on the hub for NBMA H/S networks.
For the CCIE lab, I'd practice all methods of influencing the DR election
(or no election as per the thread about 0.0.0.0 DRs).

So,
The best solution to it is configure the priority on the spoke interface to
zero and to the hub be the DR.
Therefore the "neighbor priority" command can be used in a poorly design
scenario, right?

Perhaps one "practical" use would be if you had two separate OSPF processes
running over the NBMA network in which the router was the hub for one
process and needed to be DR but was the spoke of the other process and
therefore needed to never be a DR. In this scenario, you wouldn't want an
interface priority but rather have it associated with the neighbor
statement.
I haven't personally labbed this scenario up but it seems doable to me
though I would argue that there would be a better way to design such a
network.

Hi,
I4m studying for CCIE LAB and in my tests using OSPF and under the OSPF
router configuration I can use the command "neighbor x.x.x.x priority xxx"
to specify a neighbor on NBMA network. So the problem here is that if the
neighbor that I specify in this command has the "ip ospf priority" entered
with a value different from the above this priority overrides the priority
that I set under the neighbor command, so my question is what4s the
practical function in use the neighbor x.x.x.x priority xxx command?
Tks.
