When router becomes ABR, ospf is restarted

[Senthil Kumar Nagappan]

Hi,

While adding an area and if the router becomesABR, entire ospf protocol is restarted which deletes all the neighbors and adjacencies. can we not do this gracefully with the minimum disturbance toprotocol, like resending the router lsa with B bit enabled, redoing summary-lsasand route calculation?
Thanks and Regards,Senthil
