Im thinking in theory, that is what they'd be looking for (Setting
others to 0 and setting a high priority for DR). Most people arent aware
how important the speed of the routers boot up phase is during election.
So I doubt you'd see something like that. I to, did a lot of digging for
that very instance.

Subject: Any way to force OSPF DR other than "priority 0"?
Hey all,
I have done quite a bit of Googling and DOC-CD reading, and have not
found anyone offering any clever ways to force the election of a certain
router as the DR besides setting the priority to 0 on all other routers.
For example, if I had a question that asked me to ensure Router1 was
always the DR on a certain segment without touching the configuration of
Router2 and Router3 I can set the priority very high on Router1, but if
Router1 boots a few seconds later than Router2, Router2 will be the DR
even if it has it's default priority of 1. The only way I can think to
completely guarantee Router1 is always the DR is to make the priority 0
on all other routers.
Am I missing something obvious, or am I over thinking this too much? I
have not seen this asked in any practice labs, just theorizing what
could happen.
