Re: [Pce] Benjamin Kaduk's Discuss on draft-ietf-pce-stateful-path-protection-10: (with DISCUSS and COMMENT)
Hi Mahendra, Thanks for the links. What's in the diff generally looks good; I think we may still need to have a bit more discussion here about items (1) and (4) (for the latter, I'm not sure if the plan is still to update the table to list everything or just leave it to the body text). Also, with respect to (7), I think there was at least one place in the text where we mention that the source, destination, and tunnel ID must match where we don't also mention the protection type matching. Maybe it's sufficiently less important that we don't need to mention it everywhere, but I'll mention it just in case.

[Pce] Publication has been requested for draft-farrel-pce-stateful-flags-02
Hariharan Ananthakrishnan has requested publication of draft-farrel-pce-stateful-flags-02 as Proposed Standard on behalf of the PCE working group.

New revision to ask IANA to add this document as a reference in the appropriate registry (as suggested by Hari). -Original Message- From: Pce On Behalf Of internet-dra...@ietf.org Sent: 23 September 2019 11:42 To: i-d-annou...@ietf.org Cc: pce@ietf.org Subject: [Pce] I-D Action: draft-farrel-pce-stateful-flags-02.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG of the IETF. Title : Updated Rules for Processing Stateful PCE Request Parameters Flags Author : Adrian Farrel Filename: draft-farrel-pce-stateful-flags-02.txt Pages : 6 Date: 2019-09-23 Abstract: Extensions to the Path Computation Element communications Protocol (PCEP) to support stateful Path Computation Elements (PCEs) are defined in RFC 8231. One of the extensions is the Stateful PCE Request Parameters (SRP) object. That object includes a Flags field that is a set of 32 bit flags, and RFC 8281 defines an IANA registry for tracking assigned flags. However, RFC 8231 does not explain how an implementation should set unassigned flags in transmitted messages, nor how an implementation should process unassigned, unknown, or unsupported flags in received messages. This document updates RFC 8231 by defining the correct behaviors.

Re: [Pce] Shepherd Review of draft-farrel-pce-stateful-flags-01
Hi, IMHO, including the new reference in the registry could be valuable and makes no harm. And now that the text is written, why leaving it out?
