Waiting State Question

[John Smith <jsmith4112003 at YAHOO.CO.UK>]

Hi,

When a router comes up it starts the Wait Timer before it elects the DR/BDR. It either
waits for the Wait Timer to expire or it waits for a router declaring itself as the BDR
before it decides that it needs to get out of the 'Waiting' state (it does this by
generating the Backupseen event). 

My question is why does it wait only for the BDR? Why not the DR? It can when it recieves
a HELLO from the DR know that their exists a DR and a BDR. Why not then get out of the
'Waiting' state?

Thanks,
John
