Objet : Rtgdir telechat review of draft-ietf-opsawg-l2nm-16

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?   string


A.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.
