Re: Multiple DRs/BDRs in Area 0

The role of a DR/BDR is to manage communications within a single link.
It has nothing to do with an area (other than a link belongs to an area!).

So you may have 18 separate links (broadcast type links) within area 0.
You will therefore have 18 different DR's managing the communications on
each individual broadcast segment.
