Hi, I have read this draft and It is well written and I support adoption of this work. Here are a few comments and suggestions:
1. What is VTN resource, how do we define network resource, is the resource a. the label that is switched on the path of the LSP, b. is the resource physical resource assigned to LSP? c. Is the resource a measure of the capacity of a link that is dedicated for use by the traffic on the LSP. d. Is the resource referred to node or link in the network topology? Would it be great to provide VTN resource definition in the terminology section, In addition, I also recommend you to reference RFC8413 for resource definition. 2. Section 2 said: “ The MT-specific Link or Prefix TLVs are defined by adding additional two bytes, which includes 12-bit MT-ID field in front of the ISN TLV and IP or IPv6 Reachability TLVs. ” Does this require protocol extension? Are these two bytes reserved fields? Where MT-ID is defined? In which RFC? Also ISN TLV, IP/Ipv6 Reachablity TLV, where these TLVS are defined? Please provide references. -Qin Wu 发件人: Lsr [mailto:lsr-boun...@ietf.org] 代表 Acee Lindem (acee) 发送时间: 2021年3月3日 7:28 收件人: lsr@ietf.org 主题: [Lsr] WG Adoption Poll for “Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network” - draft-xie-lsr-isis-sr-vtn-mt-03 This information draft describes how MT could be used for VTN segmentation. The authors have asked for WG adoption. This begins a three week LSR Working Group Adoption Poll for “Using IS-IS Multi-Topology (MT) for Segment Routing based Virtual Transport Network” - draft-xie-lsr-isis-sr-vtn-mt-03. I’m giving it three weeks due to the IETF next week. Please register your support or objection on this list prior to the end of the adoption poll on 3/24/2020. Thanks, Acee
