The DR/BDR election is per subnet, assuming the OSPF network type is one
that has an election (broadcast and nonbroadcast have an election,
point-to-point and point-to-multipoint do not).
The process number used on the router is only significant on the local
router. Whether you use 'router ospf 1' or 'router ospf 5' only matters to
the local router.
EIGRP is different because you are specifying the AS number, not a process
number. For EIGRP 'router EIGRP 5' specifies AS 5.

Subject: OSPF Basic Question - DR / BDR Vs Area [bcc][faked-from][bayes]
Importance: Low
Hi,
I have a question about OSPF DR/ BDR. Do I need to keep single DR / BDR for
the entire OSPF process ("router OSPF 1" is configured in all routers) or is
it specific to each area? I mean under single OSPF process ID, can I have
multiple DR / BDR that is linked to different areas?
Any response will be highly appreciated.
Thanks,
Noble
