Hi Aijun,

    Thanks much for your support and comments.

Subject: [Idr] 答复: draft-li-idr-flowspec-rpd-05.txt - WG Adoption call (10/14 to 10/28/2019)


Hi, All:



Support the adoption.  This draft can enhance the capabilities of network automation.



Some clarifications are needed:

1.  The MED and AS-Path action can only influence the inbound traffic. For outbound traffic, “Preference” value can be used. Should the draft include also the “Preference” action?

[HC]: We will update the draft to include it.

2.  The referred draft https://tools.ietf.org/html/draft-ietf-idr-wide-bgp-communities-05<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fhtml%2Fdraft-ietf-idr-wide-bgp-communities-05&data=02%7C01%7Chuaimo.chen%40futurewei.com%7C98ad2996a4184fc168a008d7592a25b5%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637075909904427377&sdata=Xw7t8roOAtnSNIYnZbNxbQeXiIuLept8b3TiBXefBxg%3D&reserved=0> is inactive now. Is there any risk to solve such problem based on it?

[HC]: We evaluated a couple of options and selected the wide community, which is simple and extensible. The WG document about the wide community should be moved forward.

3.  For policy distribution, will you consider other protocol such as PCEP? Because BGP is mainly one peer-to-peer protocol, but the policy distribution is from controller to router.

[HC]: In a network running BGP, using BGP for policy distribution has some advantages over using PCEP such as reducing capital expense and operational expense since using PCEP needs deploy, operate and maintain another (extra) protocol.





Best Regards.

主题: [Idr] draft-li-idr-flowspec-rpd-05.txt - WG Adoption call (10/14 to 10/28/2019)



This begins a 2 week WG adoption call for draft-li-idr-flowspec-rpd-05.txt

(10/14 to 10/28/2019).  You can access the draft at:



https://datatracker.ietf.org/doc/draft-li-idr-flowspec-rpd/<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-li-idr-flowspec-rpd%2F&data=02%7C01%7Chuaimo.chen%40futurewei.com%7C98ad2996a4184fc168a008d7592a25b5%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637075909904437375&sdata=BLMrDbBMbEct9YX9EoAVCGa6iQi0E3kjUi5t%2BjkRhxQ%3D&reserved=0>



In your discussion regarding this draft consider if:



1)      Passing extended policy in BGP  is useful,

2)      Passing policy in wide community atom is a technical sound mechanism,

3)      A deployment need exists for this technology.
