Yes,support. Regards, Peng Peng Liu | 刘鹏 China Mobile | 移动研究院 mobile phone:13810146105 email: liupengyjy@chinamobile.com 发件人: Susan Hares 时间: 2020/11/02(星期一)13:03 收件人: idr; 主题: [Idr] WG Adoption for draft-zhu-idr-bgp-ls-path-mtu (11/1/2020 to 11/16/2020) This begins a 2 week WG adoption call for draft-zhu-idr-bgp-ls-path-mtu-04.txt (11/1 – 11/16/2020). The authors should send in an IPR statement for this draft by 11/5 so the WG can include the IPR status in their decision. You can access the draft at: https://datatracker.ietf.org/doc/draft-zhu-idr-bgp-ls-path-mtu/ Since this draft is reference by an existing IDR draft I’ve included a bit of background below to help you place this draft into the larger context of the SR additions to BGP-LS and the draft-ietf-idr-tunnel-encaps-19.txt. This draft does continue BGP-LS additions. if you are opposed to any BGP-LS additions rather than this specific addition, please make that clear in your comment in this discussion. The authors requested a WG adoption at IETF 108. The IDR co-chairs thank the authors for their patience. This draft has been delayed by process of having a new document shepherd (Sue Hares) come up to speed on draft-ietf-idr-tunnel-encapsulation. Cheers, Sue Background =========== Segment Routing technology creates SR tunnels that are directly overlaid on MPLS or SRv6. While existing MPLS technology (LDP and RSV-TE) provides mechanisms to negotiate path MTU based on individual link MTU limits, the Segment Routing (SR) on BGP-LS Link Attribute does not pass information on MTU size per link. draft-ietf-idr-sr-policy-path-mtu-02.txt sends PATH MTU information in the tunnel-encapsulation attribute for the tunnel type SR-Policy that handles segment routing (SR) paths. However, it lacks the information to create a reasonable Path size since the BGP-LS Link Attribute does distribute this information. The draft proposes adding a new sub-TLV for MTU size to the BGP-LS Link Attribute TLV, and draft-ietf-idr-sr-policy-path-mtu-02.txt mentions this draft as one possible way to distribute the per link MTU. Questions for the authors might be: a) Are there ways to pass IGP link MTUs in the IGPs? If so, is this needed in BGP-LS b) What other mechanisms pass link MTU?
