anup,

rfc2328 has a pretty clear language on this:

10.1.  Neighbor states

     [ ... ]

         Exchange
             In this state the router is describing its entire link state
             database by sending Database Description packets to the
             neighbor.  Each Database Description Packet has a DD
             sequence number, and is explicitly acknowledged.  Only one
             Database Description Packet is allowed outstanding at any
             one time.

     [ ... ]


may i ask you why you have asked this question to the juniper-nsp list ?
is there something wrong with our OSPF implementation that you want to report ?
