RE: OSPF Priority Question

The only solutions I can come up with are the following:

1) On the DR - give it the highest priority (255). Now, give this router the RID
of 255.255.255.255 (I think that will still work).
2) IF the other router has the same priority as the "DR" the election process
will now go to the highest RID. The "DR" will win.
I believe then you have accomplished the task. The task does not say that the
router must remain the DR between reloads. It must remain the DR if the priority
is challenged.

Subject: OSPF Priority Question

If I see a question asking me to ensure a given router remains the DR for a
segment, even if a router with a higher priority is added to the network. Is
there some way to esnure this in the case of a reboot or process restart?

I know that simply adding a router with a higher priority will not "preempt" the
existing DR, but is there anything that will over-ride a priority of 255 if the
process restarts?
