Hi Zengjie, Why isn't it good enough to send a hello if the hello interval value is changed? I think you can find many-many other cases. I think to put the draft generally, whenever the content of the hello message changes we could send the hello immediately and then reset the hello timer to expire "Hello interval" seconds later. Another thing is about "Rate limiting Hello's" to prevent overwhelming of the network by hellos being sent. I think it is an essential feature.

It is unnecessary to use it when the state is more than "ExStart". ----- Original Message ----- From: "Vishwas Manral" <Vishwas@SINETT.COM> To: <OSPF@PEACH.EASE.LSOFT.COM> Sent: Thursday, December 29, 2005 6:29 PM Subject: Re: Update to OSPF Hello procedure[draft-kou-ospf-immediately-replying-hello-00.txt] Hi, Why should this not happen for every change in the neighbor status when received in a hello message? Whenever the contents of the hello message change we could send the message immediately. Is there a Minimum interval between which if we get consecutive hello's we do not process them, just like LSA's?

The draft can be found here: http://www.ietf.org/internet-drafts/draft-kou-ospf-immediately-replying- hello-00.txt This memo documents an extension of the OSPF protocol to reach "ExStart" state more quickly. Currently, the OSPF behavior requires the Hello Packet to be sent between the neighbors every HelloInterval. This document proposes to generalize the use of Immediately Replying Hello which could reduce the time required to reach the OSPF "ExStart" state and expedite the routing table convergence.
