[Ballot discuss]
Thank you for a clearly written document.  I have a couple technical concerns that I think should
be quick to handle.

  Section 4.1: "A mid-point LSR MAY send an unsolicited PathErr with the Notify error
  code and sub-code "Preferable P2MP-TE Tree Exists" to the ingress
  node to notify of a preferred P2MP-TE LSP tree when it determines it
  exists. "  I think it would be better to have some text about dampening so that PathErrs are
  emitted at a reasonable rate.

  Related, I see " The sending of an RSVP PathErr with the Notify error code and
  "Preferable P2MP-TE Tree Exists" sub-code to the ingress node
  notifies the ingress node of the existence of a preferable P2MP-TE
  LSP tree and upon receiving this PathErr, the ingress node MUST
  trigger re-optimization of the LSP using the MBB method with a different LSP-ID."
  At a minimum can you please explain why this would be a MUST instead of a MAY or a SHOULD?
  I believe this would need to be in the document to be clear  what the
  assumptions are.  The rest of the document is providing mechanisms for fragmenting
  and requesting reoptimization checks.

(Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs:

The IANA Services Operator has completed its review of draft-ietf-teas-p2mp-loose-path-reopt-08.txt. If any part of this review is inaccurate, please let us know.

We have a question about one of the actions requested in the IANA Considerations section of this document.

The IANA Services Operator understands that, upon approval of this document, there are three actions which we must complete.

First, in the Attribute Flags subregistry of the Resource Reservation Protocol-Traffic Engineering (RSVP-TE) Parameters registry located at:

http://www.iana.org/assignments/rsvp-te-parameters

a new Attribute Flag is to be registered as follows:

Bit No: [ TBD-at-Registration ]
Name: P2MP-TE Tree Re-evaluation
Attribute Flags Path: Yes
Attribute Flags Resv: No
RRO: No
ERO:
Reference: [ RFC-to-be ]

IANA Services Operator Question --> What should be the entry for (carried in) ERO for this registration?

Second, in the Sub-Codes - 25 Notify Error subregistry of the Error Codes and Globally-Defined Error Value Sub-Codes subregistry of the Resource Reservation Protocol (RSVP) Parameters registry located at:

http://www.iana.org/assignments/rsvp-parameters

a single new Sub-Code is to be registered as follows:

Value: [ TBD-at-registration ]
Description: Preferable P2MP-TE Tree Exists
Reference: [ RFC-to-be ]

Third, in the Class Names, Class Numbers, and Class Types subregistry of the Resource Reservation Protocol (RSVP) Parameters registry also located at:

http://www.iana.org/assignments/rsvp-parameters

a new Class number is to be allocated as follows:

Class Number: [ TBD-at-Registration ]
Class Name: S2L_SUB_LSP_FRAG
Reference: [ RFC-to-be ]

The IANA Services Operator understands that these three actions are the only ones 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. This message is only to confirm what actions will be performed.

Thank you,

  S2L sub-LSPs, both using Sub-Group-Based Re-optimization method, or
  the entire P2MP-TE LSP tree using the Make-Before-Break (MBB) method.

Standards Track.

Standards Track is apt because the document defines P2MP RSVP related
formats and behaviors. [However, it is to be noted that the P2P version
of this (RFC 4736) was published as an Informational document]

Re-optimization of a Point-to-Multipoint (P2MP) Traffic Engineered
(TE) Label Switched Path (LSP) may be triggered based on the need to
re-optimize an individual source-to-leaf (S2L) sub-LSP or a set of
S2L sub-LSPs, both using Sub-Group-Based Re-optimization method, or
the entire P2MP-TE LSP tree using the Make-Before-Break (MBB) method.
Mechanisms that facilitate path re-optimization of loosely routed
Point-to-Point (P2P) TE LSPs include a method for the ingress node to
trigger a new path re-evaluation request and a method for the mid-
point node to notify availability of a preferred path.  This document
discusses the application of these mechanisms to the re-optimization
of loosely routed P2MP-TE LSPs, identifies issues in doing so and
proposes procedures to address them.

This document defines Resource Reservation Protocol (RSVP) signaling
extensions to allow the ingress node of a loosely routed P2MP-TE LSP
to request the re-evaluation of the LSP tree downstream of the node,
and a mid-point node to notify to the ingress node that a preferable
tree for the P2MP-TE LSP exists.  For re-optimizing a group of S2L
sub-LSPs in a tree using the Sub-Group-Based Re-optimization method,
an S2L sub-LSP descriptor list can be used to signal one or more S2L
sub-LSPs in an RSVP message.  This RSVP message may need to be
semantically fragmented when large number of S2L sub-LSPs are added
to the descriptor list.  This document introduces the notion of a
fragment identifier to help recipient nodes unambiguously reconstruct
the fragmented S2L sub-LSP descriptor list.

> Working Group Summary

>  Was there anything in WG process that is worth noting? For
>  example, was there controversy about particular points or
>  were there decisions where the consensus was particularly
>  rough?

This document moved from the CCAMP WG to TEAS WG as part of the
routing WG changes. There was some serious debate regarding the
introduction of fragment-identifier for S2L sub-LSP Descriptor.
All concerns raised in regard to this have been addressed by the
authors.

The base GMPLS signaling protocol has been implemented. The procedures
discussed in this document are compatible with earlier implementations.
The Acknowledgements section of the draft does hint at the existence of
at least of one implementation. There have been no other public
statements on implementation.

The Document Shepherd has reviewed the document as it has progressed
through the WG (first CCAMP, then TEAS). The Shepherd believes this
document is ready for publication.

> (4) Does the document Shepherd have any concerns about the depth or

No.

No.

> If so, describe the review that took place.

N/A.

No specific concerns.

Yes, see thread -
https://www.ietf.org/mail-archive/web/teas/current/msg01614.html


> (8) Has an IPR disclosure been filed that references this document?
> If so, summarize any WG discussion and conclusion regarding the IPR
> disclosures.

Yes, a couple of IPR disclosures have been filed that reference this
document (see https://datatracker.ietf.org/ipr/2307/ and
https://datatracker.ietf.org/ipr/2895/). There was no WG discussion
regarding the IPR disclosures.


> (9) How solid is the WG consensus behind this document? Does it

Solid among those who are interested. "strong concurrence of a few
individuals, with others being silent" is a reasonable
characterization.

> (10) Has anyone threatened an appeal or otherwise indicated extreme

No extreme discontent seen.

> document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts
> Checklist). Boilerplate checks are not enough; this check needs to be
> thorough.

The document passes all ID nits except for one. The following error is
listed by the idnits tool:
** Downref: Normative reference to an Informational RFC: RFC 4736

> (12) Describe how the document meets any required formal review
> criteria, such as the MIB Doctor, media type, and URI type reviews.

N/A.

Yes.

> (14) Are there normative references to documents that are not ready for

No.

> (15) Are there downward normative references (see RFC 3967)?
> If so, list these downward references to support the Area Director in
> the Last Call procedure.

Yes. There is one downward normative reference to an Informational RFC
(RFC 4736) referenced in this document.

> (16) Will publication of this document change the status of any

No.

The IANA section was fully reviewed by the document shepherd. All protocol
extensions that the document makes are associated with the appropriate
reservations in IANA registries.
