Re: [v6ops] draft-xiao-v6ops-nd-deployment-guidelines discussion

Hi XiPeng,

I think this summary is important and should be adopted as an informational document by the working group.

However, there is much work todo on the way to getting it out:

 - First and foremost, the tone and attitude is dangerous: 
   It primarily gives the impression that IPv6 is not production ready.
   ND has its security and performance issues, as ARP has – they are intrinsic to the kind of protocol. 
   They do not really differ that much in severity but in details (multicast vs. broadcast).

 - We need to focus on the solutions and explain where they need to be implemented.

 - The draft is still very carrier centric. I would expect more things about ND handling
   in wireless controllers and DCs to be useful for enterprise environments.

 - We should clearly mark things like SEND as exotic

Finally, I guess an informational document spelling out interactions between ND, SlAAC, DHCPv6 would also be helpful. Whether this is one or more documents, I am not sure yet.

AVE!

This draft is part of that effort.  Therefore, the adoption of this draft will encourage more contributors to do the same.  Thank you very much for your consideration and support.
