Answer / ram ji agarwal
DR and BDR election process is done by OSPF protocol. DR
will that system who has lowest ospf priority and if all
the routers have same OSPF priority so that router will be
DR that has highest ip address all other who has higher
ospf priority and lower ip address than DR that will be
elected as BDR.

Answer / shrynth
Raghu Kumar is absolutely correct... DR and BDR is elected by Hello messeges. Whoever responds first becomes DR.
Is This Answer Correct ? | 1 Yes | 0 No |
DR and BDR election is done via the Hello protocol. Hello
packets are exchanged via IP multicast packets (Appendix B)
on each segment. The router with the highest OSPF priority
on a segment will become the DR for that segment. The same
process is repeated for the BDR. In case of a tie, the
router with the highest RID will win. The default for the
interface OSPF priority is one. Remember that the DR and BDR
concepts are per multiaccess segment. Setting the ospf
priority on an interface is done using the ip ospf priority
<value> interface command.
A priority value of zero indicates an interface which is not
to be elected as DR or BDR. The state of the interface with
priority zero will be DROTHER.

Note: OSPF is routing protocol not a DR Or BDR selection
protocol...This is mine concern..nw waiting for the any
other concept if it is there..Gtech
