Hi Anju, 1) Well, if you want to reduce the size of the database in an Area, you could configure the area as either Stub or NSSA. You can check the draft http://www.ietf.org/internet-drafts/draft-ietf-ospf-nssa-update-11.txt <http://www.ietf.org/internet-drafts/draft-ietf-ospf-nssa-update-11.txt> and RFC2328 for details. Besides in OSPF there is a technique called DBOverflow, that allows handling of unanticipated database overflows - RFC1765. 2) You may like to see the flooding procedure Section 13, and section 10.3 neighbor state machine. The basic idea is that a DR/BDR is elected for each broadcast link, and non-DR routers form adjacencies with only DR/BDR. The DR-other sends LSUpdate packets to the address ALLDRRouters and DR/BDr send to ALLSPF routers.

Thanks.
