Hi Med,
Thanks for working on my comments. Just one question inline below.
Thanks, Yingzhen
Hi Yingzhen,Many thanks for the review. Please see inline.

Reviewer: Yingzhen Qu Review result: Has Nits
I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir
Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft.
Document: draft-ietf-opsawg-l2nm-16 Reviewer: Yingzhen Qu Review Date: 05/23/2022 IETF LC End Date: unknown Intended Status: Standards Track
Summary: Thanks to the authors for working on this document. I think it's almost ready for publication. There is one error in the appendix A.2 example that should be fixed before publication, and there are a few minor issues/nits that may be considered before publication.
Major Issues:
Appendix A.2: libyang[0]: Node "ldp-pw-type" not found as a child of "ldp-or- l2tp" node. (path: Schema location /ietf-l2vpn-ntw:l2vpn-ntw/vpn-services/vpn-service/vpn-nodes/vpn- node/signaling-option/signaling-option/ldp-or-l2tp/ldp-or-l2tp, data location /ietf-l2vpn-ntw:ldp-or-l2tp, line number 61.) This should "t-ldp-pw-type".
[Med] Good catch. Fixed. Thanks.General Comment: A lot of descriptions about nodes exported from RFC9181 in section 7 are redundant from RFC9181.
[Med] We tried to find a balance between pointing to RFC9181 and ease the readability of the document. Minor Issues and Nits (line numbers are from idnits):
397 Also, the L2NM uses the IANA-maintained modules "iana- bgp-l2-encaps" 398 (Section 8.1) and "iana-pseudowire-types" (Section 8.2) to identify a 399 Layer 2 encapsulation type.
[nits]: encapsulation type and pseudowire type.
[Med] ACK. Changed to "encapsulation and pseudowire types"409 view of the L2VPN service. Such a view is only visible within the 410 service provider and is not exposed outside (to customers, for 411 example).
[nits]: Visible within/visible to
[Med] Fixed, thanks. 500 'name': Sets a name to uniquely identify an ES within a service 501 provider network. This name is referenced in the VPN network 502 access level of the L2NM (Section 7.6).
[major]: I don't see where the "name" is referenced.
[Med] This is called here: +--rw group* [group-id] | +--rw group-id string | +--rw precedence? | | identityref =====> | +--rw ethernet-segment-identifier? stringA.4 provides an example how the segment is created and then how the name is called in the L2NM.Updated the text with a pointer to that appendix.
[Yingzhen]: “ethernet-segment-identifier” is defined as string here in stead of a leafref, why? 577 The 'vpn-profiles' container is used by the provider to maintain a 578 set of common VPN profiles that apply to VPN services (Section 7.2).
[nits]: to be consistent with section 7.2: to maintain/to define and maintain
[Med] OK. 629 This document does not make any assumption about the exact definition 630 of these profiles. The exact definition of the profiles is local to 631 each VPN service provider.
[nits]: These two sentences should be rewritten to be concise.
[Med] OK, shortened to: "The exact definition of these profiles is local to each VPN service provider." 2785 leaf name { 2786 type string; 2787 description 2788 "Includes the name of the Ethernet Segment (ES)."; 2789 }
[nits]: please update the description
[Med] Updated to: "Includes the name of the Ethernet Segment (ES) that is used to unambiguously identify an ES."; 3824 container active-global-parameters-profiles { 3825 description 3826 "Container for a list of global parameters 3827 profiles."; 3828 list global-parameters-profile { 3829 key "profile-id"; 3830 description 3831 "List of active global parameters profiles."; 3832 leaf profile-id { 3833 type leafref { 3834 path "../../../../../global- parameters-profiles" 3835 + "/global-parameters- profile/profile-id"; 3836 } 3837 description 3838 "Points to a global profile defined at the 3839 service level."; 3840 } 3841 uses parameters-profile; 3842 } 3843 }
[question]: profile-id is a leafref to the "global-parameters- profile", where grouping "parameters-profile" is already included/used, why is it used here again? is it for configuration overwritten?
[Med] We need to call out a specific profile (and use the same id) to be activated at the node level. Some of the parameters will be overridden. _________________________________________________________________________________________________________________________Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent doncpas etre diffuses, exploites ou copies sans autorisation.
