Hi Chongfeng,

I agree with your point.  This draft is about IPv6 first-hop deployment. In this version, we have changed the title of the draft to “Selectively Applying Host Isolation to Simplify IPv6 First-hop Deployment”.  But we didn’t change the file name.  We can change it in a new version.

If you can further review and comment on the draft we would greatly appreciate it!

XiPeng

Hi, Xipeng,
I 'd like to make a personal comment on the term "deployment".  Usually, this term refers to the deployment and application of a device or system for network operators or enterprise customers who operate their own network. Specific protocols such as ND are part of the device or system. Whether or how the device supports ND should be decided prior to the phase of operator deployment.  So is it replaced by other terms? What's your opinion?

Best regards
Chongfeng

Dear folks,



We submitted a major revision of ND-deployment-guidelines draft.  We believe its quality is significantly improved.  The key points are below.  Your review and comments will be greatly appreciated.    XiPeng & the co-authors



Problem statement:

•         Various issues and solutions are documented in more than 30 RFCs. It is difficult to keep track of all these issues and solutions, and how the various solutions fit together.   These include: ND Proxy, Optimistic ND, ND for mobile broadband, ND for fixed broadband, ND Mediation, Operational ND Problems, Wireless ND (WiND), DAD Proxy, SAVI/RA-Guard/RA-Guard+, Enhanced DAD, Scalable ARP, Reducing Router Advertisements, Unique Prefix Per Host, GRAND, Proxy ARP/ND for EVPN etc.



This draft:

•         Summarizes the known ND issues and optimization solutions into a one-stop reference.

•         Present an insight: isolating hosts is effective in solving ND issues.

•         Propose 4 isolation methods and discuss their applicability: P2P link & subnet isolation, P2MP link & subnet isolation, GUA isolation, proxy isolation

•         Describe guidelines for selecting a suitable isolation method based on the deployment scenario.



Regards,



Xipeng Xiao, Ph.D.

Abstract:

   Neighbor Discovery (ND) is the key protocol of IPv6 first-hop. ND

   uses multicast extensively and trusts all hosts. In some scenarios

   like wireless networks, multicast can be inefficient. In other

   scenarios like public access networks, hosts may not be trustable.

   Consequently, ND issues may happen in various scenarios. The issues

   and solutions are documented in more than 30 RFCs. It is difficult

   to keep track of all these issues and solutions, and how the various

   solutions fit together. Therefore, deployment guidelines are needed.



   This document firstly summarizes the known ND issues and

   optimization solutions into a one-stop reference. Analyzing these

   solutions reveals an insight: isolating hosts is effective in

   solving ND issues. Four isolation methods are proposed and their

   applicability is discussed. Guidelines are then described for

  selecting a suitable isolation method based on the deployment

   scenario.
