Yes, support with comments and questions. 1. Q: Last time we discussed that do we need to carry SRv6 Endpoint behavior TLV for END.X SID, I think the answer is no. This TLV is used for SRv6 SID NLRI only, correct? Just to double check. 2. Q: if we meet an error in BGP-LS, do we have any error handling? Like in PCEP, we need to check the sum of lengths each part of SRv6 SID, if the length is larger than 128 bits, this is an error. But I don't see the error handling in BGP-LS extensions. It may be good to add some text of usage, processing and handling of TLVs. Current revision seems a little bit simple to me. a) Is the SRv6 technology ready for deployment or are there known issues? Yes. b) Will SRv6 provide valuable support for deployments of BGP-LS in support of source routing (aka spring)? Yes. c) Is this draft ready for publication? If you know of additional implementations, please send a note to the idr chairs with the information or respond to this email. With comments. Cheng From: Idr [mailto:idr-bounces@ietf.org] On Behalf Of Susan Hares Sent: Monday, November 2, 2020 11:25 AM To: idr@ietf.org Subject: [Idr] IPR call and WG LC for draft-ietf-idr-bgpls-srv6-ext-04.txt (11/1/2020 to 11/16/2020) This begins an IPR call and a 2 week WG LC for draft-ietf-idr-bgpls-srv6-ext-04.txt (11/1 to 11/16/2020) You can access the draft at: https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-ls-flex-algo/ This draft focus on the BGP-LS support for SRv6. Spring has proposed the SRv6 support in RFC8402 (see section 3.1.3 for mechanisms and section 8.2 for Security considerations). There are two implementations: Cisco and GoBGP You can see the implementation report at: https://trac.ietf.org/trac/idr/wiki/draft-ietf-idr-bgpls-srv6-ext%20implementations In your responses, please consider the following questions: a) Is the SRv6 technology ready for deployment or are there known issues? b) Will SRv6 provide valuable support for deployments of BGP-LS in support of source routing (aka spring)? c) Is this draft ready for publication? If you know of additional implementations, please send a note to the idr chairs with the information or respond to this email. Cheers, Susan Hares
