Re: Update to OSPF Hello procedure[draft-kou-ospf-immediately-replying-hello-00.txt]

[Zengjie Kou <[e-mail]>]

Hi,Manav
    I don't find any harm except a few additional hello packets before the state reaches "ExStart".

    The Immediate Hello do not affect which router will be elected DR. It only expedite the election.

thanks
kou.
