Zhengquiang: <wg-chair hat on> This is a good question to raise during the adoption of an IDR draft. I hope that the authors of the draft and others will indicate why they desire the BGP-LS method of allocating the SIDs. As you are aware, the NETCONF based mechanism utilize a secure transport during the allocation. BGP SHOULD run over an authenticated transport (MD5 or better yet TLS), but all BGP peers within a network may not run over the secure transport. <wg-chair hat off> <wg-member hat on> As a WG member, I realize that each network makes choices on allocating SIDs and their control path. Some of the reasons may not be able to be disclosed on a public mailing list. However, it would be good for the authors to provide some reasons “Why BGP-LS” for allocation. <wg-member hat off> Sue Hares From: Idr [mailto:idr-bounces@ietf.org] On Behalf Of li zhenqiang Sent: Wednesday, April 24, 2019 3:51 AM To: Susan Hares; idr@ietf.org Cc: draft-ietf-teas-enhanced-vpn; draft-dong-lsr-sr-enhanced-vpn Subject: Re: [Idr] draft-wu-idr-bgp-segment-allocation-ext-02.txt [4/18 - 5/2/2019] - 2 week WG adoption call Hi Sue and All, Zhenqiang Li from China Mobile. I see the value to allocate SIDs in a centralized way, especially for the SIDs representing network resources as proposed in https://datatracker.ietf.org/doc/draft-ietf-teas-enhanced-vpn/ and https://datatracker.ietf.org/doc/draft-dong-lsr-sr-enhanced-vpn/. However, I want to know why BGP-LS is chosen to to complete this work, not PCEP or netconf? BGP-LS is mainly used to collect information from network, other than configure network from a controller. Best Regards, Zhenqiang Li _____ li_zhenqiang@hotmail.com From: Susan Hares <mailto:shares@ndzh.com> Date: 2019-04-18 22:04 To: idr@ietf.org Subject: [Idr] draft-wu-idr-bgp-segment-allocation-ext-02.txt [4/18 - 5/2/2019] - 2 week WG adoption call This begins a 2 week WG Adoption call for draft-wu-idr-bgp-segment-allocation-ext-02.txt. You can access the draft at: https://datatracker.ietf.org/doc/draft-wu-idr-bgp-segment-allocation-ext/ In your comments, consider: 1) Does this draft mechanisms for extending BGP-LS to provide IDs for allocation provide a beneficial addition to BGP mechanisms for segment routing? 2) Is the mechanism well-formed enough to adopted as a WG draft? 3) Do you see any problems with using these IDs for flow redirection? 4) Do you support extending BGP-LS? 5) Should we provide an early allocation for this technology? 6) Do you know of any early implementations? By answering these questions during WG Adoption call, you will help John and I determine what issues need to be considered prior to finalizing this WG draft. Your answer will help us increase the speed of processing BGP-LS drafts. If enough people indicate that they wish an early allocation upon adoption, I will then send this early allocation to Alvaro. Sue Hares PS – I’m trying new methods of WG adoption calls to help speed up the process in IDR WG. Please send any thoughts on these new methods to me or John.
