Hi, Susan and Authors of this draft: Sorry to reply this LC so late. The followings are my suggestions to this draft based on the discussion related to the mail thread https://mailarchive.ietf.org/arch/msg/idr/vSeflAMCMPL25N4nBOZu8yG19HA Is it too late to response? Please see the reply below in line. Best Regards. Aijun Wang Network R&D and Operation Support Department China Telecom Corporation Limited Beijing Research Institute,Beijing, China. 发件人: Susan Hares [mailto:shares@ndzh.com] 发送时间: 2018年3月8日 0:41 收件人: 'idr wg' 主题: [Idr] WG LC for draft-ietf-idr-bgp-ls-segment-routing-ext-04 (March 7 to March 21) This begins a 2 week WG LC for draft-ietf-idr-bgp-ls-segment-routing-ext-04. txt from March 7th to March 21. During your discussion in the WG LC, please indicate the following things: 1) Do you think BGP should carry these link state information regarding segment routing, “Source Router Identifier (Source Router-ID) TLV” should be stripped off this draft, because there are other situations(more general scenarios besides SR) that requires the source router of the prefixes, as described in https://datatracker.ietf.org/doc/draft-wang-idr-bgpls-inter-as-topology-ext/ and discussed in mail thread https://mailarchive.ietf.org/arch/msg/idr/-T7U1yg8DmSdDmtyfqBgtnkO4I0 2) Are there any technical issues with this draft? Some clarifications should be added in the following sections: a) Regarding the usage of SID/Label sub-TLV: “2.1.2 SR-Capabilities TLV”, “2.1.4 SR Local Block TLV” requires all the presence of “SID/Label sub-TLV”. It is more clear to indicate this “SID/Label sub-TLV” represent the base of the “Range Size”. b) Regarding the inconsistence definition among “ISIS/OSPF/OSPFv3/BGP-LS” : “2.2.1 Adjacency SID”, “2.2.2 LAN Adjacency SID TLV”,”2.3.1 Prefix-SID TLV” Note for “Length” field: 2-bytes “Reserved” filed should be added when copying the corresponding fields from IS-IS protocol c) Regarding the definition “Range TLV”: if the “Length” filed is 4, how to detect the existence of “sub-TLV?” Is it more clear to rename the “Range TLV” as “Mapping-Range TLV”, so as to distinguish it from the previous “Range filed” in “2.1.2 SR-Capabilities TLV”? d) Regarding the contents for “3. Procedures”: Suggest to delete this section, because: -------Contents in section 3.1, 3.2 has been mentioned in corresponding TLV definition(section 2.3.1), there is no more new information in this section. -------Contents in section 3.3 and 3.4 should be merged with section 2.3.4 to eliminate the inconsistence arose in future when update parts of them. 3) Is this draft is ready for publication? If the above issued is solved, it is ready for publication.
