Section 4 … [Ballot comment] If "srgb" already stands for "segment routing global block", what does the extra "global" in "global-srgb" mean? I support Roman's Discuss. Section 4 The module ietf-segment-routing-mpls augments the "/rt:routing/ sr:segment-routing:" with a sr-mpls container. This container defines all the configuration parameters related to segment-routing MPLS data plane. nit: missing "the" ("the segment-routing MPLS data plane"). * Connected prefixes : maps connected prefixes to a segment ID. Advertisement of the mapping will be done by IGP when enabled for segment routing (see Section 5). The SID value can be expressed as an index (default), or an absolute value. The "last-hop-behavior" configuration dictates the PHP behavior: "explicit-null", "php", or "non-php". Is the penultimate hop here a SR hop (a la PSP) or an underlying routing protocol hop? Section 5.1.1.1 (i.e., a bundle of adjacencies). The "advertise-adj-group-sid" configuration controls whether or not an additional adjacency SID is advertised. nit: I think it is better to say "controls for which group(s) an additional adjacency SID is advertised" -- the current wording implies that there would only be one additional SID, but IIUC it is one additional SID per group. both interfaces L3 and L4. This will result in R1 advertising an additional Adj-SID for each adjacency, for example a Adj-SID with S flag set and value of 400 will be added to L1 and L2. A Adj-SID with S flag set and value of 500 will be added to L3 and L4. As L1/L2 and L3/L4 does not share the same "group-id", a different SID value will be allocated. I don't think I remember where the 'S flag' is specified (or the 'B-flag' in the following section). This is still in the protocol-independent part of the model/document, right? (Also, nit, please consistently hyphenate or don't hyphenate the "X flag" construction.) Section 8.2 grouping prefix-sid { description "This grouping defines cfg of prefix SID."; nit: I think we can write out "config" or even "configuration" here. Section 8.3 feature max-sid-depth { description "Support for signaling MSD (Maximum SID Depth) in IGP."; reference "RFC 8476: Signaling Maximum SID Depth (MSD) Using OSPF RFC 8491: Signaling Maximum SID Depth (MSD) Using IS-IS RFC 8814: Singaling Maximum SID Deppt (MSD) Using the Border Gateway Protocol (BGP) - Link State"; } I feel like a few more words are in order -- do I claim the feature if I inplement only one IGP's signaling? Or do I need to have all three? Or "just" have support for it in all the IGPs that I support? enum "dual" { description "Two Adj-SIDs will be associated with the adjacency if the interface is protected. In this case, will be advertised with backup flag set, the other will be advertised with the backup flag clear. In case protection is not configured, single Adj-SID will be advertised with the backup flag clear."; nit: some missing words, maybe "In this case, one will", ", and the other will", "a single Adj-SID will". description "Node MSD is the lowest MSD supported by the node."; nit(?): "lowest link MSD"? list label-blocks { [...] leaf lower-bound { [...] leaf upper-bound { [...] leaf size { [...] leaf free { [...] leaf used { Is there really all the internal redundancy between these that it sounds like there is? Would we benefit from any YANG-level constraints or other enforced consistency checks? notification segment-routing-global-sid-collision { [...] leaf received-target { type string; description "Target received in the router advertisement that caused the SID collision."; I'm not entirely sure that string is the right type here (it cannot handle arbitrary binary strings and must be UTF-8) ... if it's a SID, don't we normally represent those as uint32? Or if it's a proper route-target structure that seems like it would need to allow arbitrary binary content. (The original-target leaf would be similarly affected, of course.) Section 9 I believe at this point we're converging on using RFC 8446 as the TLS reference (even though the nominal boilerplate template has had RFC 5246). This would not imply a requirement to actually use TLS 1.3; it just reflects that RFC 8446 is the current IETF reference for TLS. Section 12.1 I guess RFC 3688 could probably be just an informative reference. So could NETCONF and RESTCONF (6241 and 8040). |

Even though the model is incomplete, I … [Ballot comment] (1) I have a significant concern about the incomplete representation of the MSD in this document. Even though the model is incomplete, I am not balloting DISCUSS because this point should be easy to address. grouping max-sid-depth { description "Maximum SID Depth (MSD) operational state grouping."; leaf node-msd { type uint8; description "Node MSD is the lowest MSD supported by the node."; } container link-msds { description "MSD supported by an individual interface."; list link-msds { key "interface"; description "List of link MSDs."; leaf interface { type if:interface-ref; description "Reference to device interface."; } leaf msd { type uint8; description "MSD supported by the interface."; } } } } (a) While there is a "type" mentioned, that seems to correspond to the MSD-Value. The MSD-Type is not included above. (b) Note that the MSD is really a pair of MSD-Type/MSD-Value. The description above, even if extended to also include the MSD-Type, seems to allow for a single pair, where multiple could be advertised per node/link. (c) The ERLD (entropy-readable-label-depth, for which references should be included) is advertised in the IGPs using the same mechanism as the MSD: using the ERLD-MSD type. IOW, the separation of the ERLD from the MSD in the module is redundant/incorrect. (d) MSD is a good example of a feature that is common to both the MPLS and IPv6 dataplanes and should be in the common part of the model, not defined separately for each. (2) §3: "Module ietf-segment-routing-common defines generic types and groupings that SHOULD be reused by IGP extension modules." The SHOULD is out place because the module is either supported or not, if it isn't then there is no effect on interoperability because the IGP extension module presumably chose a different option. s/that SHOULD/to (3) §3: There should be a representation of the ietf-segment-routing-common module in this section. |

Should this document reference that document's {extended-,}system-id definitions? I just wonder if this other document is somehow "more authoritative" for this type of thing, and therefore wondering whether referencing it would be the right thing to do. |

Read my ABSTAIN ballot as "I oppose this document but understand that others differ and am not going to stand in the way of the others" per https://www.ietf.org/standards/process/iesg-ballots/ . Please note that I am neither a YANG expert nor a segment routing one (hence my ABSTAIN rather than a DISCUSS). Based on title, I was expecting this document to be generic and to see companion YANG models for the MPLS and IPv6 data planes but it seems that this document also augments *only* the MPLS one. The asymmetry does not look good to me... Are the authors/WG sure that the IPv6 YANG model can also be specified by augmenting this model (draft-ietf-spring-srv6-yang-00 is still a -00 ...) and relying on types defined in ietf-segment-routing-common ? Especially when noting that the authors are different ? The YANG model for SR is really short (mostly meaningless except for one more tag in the namespace tree): "module: ietf-segment-routing augment /rt:routing: +--rw segment-routing" To be honest, I strongly dislike the fact that there is no common element between the YANG modules for MPLS and IPv6 data planes inside ietf-segment-routing. I admit that I am not an SR expert but I would have expected more common elements: policies, routing protocols, SID, link bundles, ... even if the leaves could be instantiated as generic types to be augmented later. One additional regret is that the document shepherd write-up is really really short. But it includes the most important element (to my eyes): the WG feedback & consensus. Regards, -éric |

If any part of this review is inaccurate, please let us know. The IANA Services Operator understands that, upon approval of this document, there are two actions which we must complete. First, in the ns registry on the IETF XML Registry page located at: https://www.iana.org/assignments/xml-registry/ three, new namespaces will be registered as follows: ID: yang:ietf-segment-routing URI: urn:ietf:params:xml:ns:yang:ietf-segment-routing Filename: [ TBD-at-Registration ] Reference: [ RFC-to-be ] ID: yang:ietf-segment-routing-common URI: urn:ietf:params:xml:ns:yang:ietf-segment-routing-common Filename: [ TBD-at-Registration ] Reference: [ RFC-to-be ] ID: yang:ietf-segment-routing-mpls URI: urn:ietf:params:xml:ns:yang:ietf-segment-routing-mpls Filename: [ TBD-at-Registration ] Reference: [ RFC-to-be ] As this document requests registrations in a Specification Required (see RFC 8126) registry, we will initiate the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK." Second, in the YANG Module Names registry on the YANG Parameters registry page located at: https://www.iana.org/assignments/yang-parameters/ three, new YANG modules will be registered as follows: Name: ietf-segment-routing File: [ TBD-at-Registration ] Maintained by IANA?

The IANA Services Operator understands that these are the only actions required to be completed upon approval of this document. Note: The actions requested in this document will not be completed until the document has been approved for publication as an RFC.

Please send substantive comments to the last-call@ietf.org mailing lists by 2020-11-30. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines a YANG data model for segment routing configuration and operation, which is to be augmented by different segment routing data planes. The document also defines a YANG model that is intended to be used on network elements to configure or operate segment routing MPLS data plane, as well as some generic containers to be reused by IGP protocol modules to support segment routing. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-spring-sr-yang/ No IPR declarations have been submitted directly on this I-D. |
