Hi PIM & MSR6 : I feel the last-calling document in SPRING may be useful to understand MSR6 and related work.
This Spring document[1] defines an SRv6 SID End.Replicate to perform a multipoint transport behavior statefully. The MSR6 document[2] defines an SRv6 SID End.RGB to perform a multipoint transport behavior statelessly. This Spring document [1] uses an SRv6 SID and IPv6 extension header. The MSR6 document [2] uses an SRv6 SID and IPv6 extension header. This document [1] clearly stated that “...to establish P2MP trees in SR domain”. The document [3], as the preceding research of MSR6, stated that, “… the BIERv6 domain is the same as SRv6 domain”. This document [1] clearly demonstrates how the idea of “using a unicast forwarding plane to perform multipoint transport” is adopted. This argument [4] about MSR6 is that “using a unicast forwarding plane to perform multipoint transport” is bad/failed idea (please correct me if I understand it wrong). This Spring document[1] has reached its lastcall in the wide IETF community. The MSR6 document [2], and the preceding research[3], has been blocked since 2019(may be earlier than the End.Replicate), and the claim about it had been variable over time: l Firstly, the claim was that, SRv6 is a new thing and unmature and some terriable hijack. l And then, the claim was that, it does not comply with BIER architecture. l And then, the claim was that, the BIER wg don’t need it or work on it. l And then, the claim was that, the MSR6 makes no difference than BIER. l And sometimes, the claim was that, using unicast forwarding plane is bad/failed (loop). (Due to the so long timeline of these discussions, I do not have the link on each of above claim, but if it is interested, I can try to find them) Thanks, Jingrong [1] https://datatracker.ietf.org/doc/draft-ietf-spring-sr-replication-segment/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-ietf-spring-sr-replication-segment%2F&data=05%7C01%7Cjames.n.guichard%40futurewei.com%7C754580bd81ff45ecdb9108dad152afe7%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C638052450380683369%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Jf7bnxwWGDztXPD1FvW%2Bi%2BVAb3qnqOBUGudZK4KiGEY%3D&reserved=0> [2] https://datatracker.ietf.org/doc/draft-lx-msr6-rgb-segment/ [3] https://datatracker.ietf.org/doc/html/draft-xie-bier-ipv6-encapsulation-10 [4] https://mailarchive.ietf.org/arch/msg/msr6/eMUWpjSbo3THJLEXe_t1Pt5PTyc/ 本邮件及其附件可能含有华为公司的保密信息，仅限于发送给上面地址中列出的个人或群组。禁止任何其他人以任何形式使用（包括但不限于全部或部分地泄露、复制、或散发）本邮件中的信息。如果您错收了本邮件，请您立即电话或邮件通知发件人并删除本邮件！ This e-mail and its attachments may contain confidential information from HUAWEI, which is intended only for the person or entity whose address is listed above.
