Hi there I have been selected to do a routing directorate "early" review of this draft. draft-ietf-pce-lsp-extended-flags-03 - Label Switched Path (LSP) Object Flag Extension of Stateful PCE<https://datatracker.ietf.org/doc/draft-ietf-pce-lsp-extended-flags/03/>
The routing directorate will, on request from the working group chair, perform an "early" review of a draft before it is submitted for publication to the IESG. The early review can be performed at any time during the draft's lifetime as a working group document. The purpose of the early review depends on the stage that the document has reached. As this document is already post working group last call, my focus for the review was to determine whether the document is ready to be published. For more information about the routing area directorate, please see RtgDir - Routing Area Wiki (ietf.org)<https://trac.ietf.org/trac/rtg/wiki/RtgDir>. Summary I have some minor concerns about this document that I think should be resolved before the publication process begins. Comments Section 3.2 Please could you add explicit statements that unused flags should be set to zero on sending and ignored on receipt? I know we have RFC 8786 which covers this, but I think it does no harm to say it explicitly anyway. Probably worth adding a normative reference to RFC 8786 as well. Section 5.1.2 Please note in the instructions to IANA that bits 0-31 should initially be marked as "Unassigned" and that bits with a higher ordinal than 31 will be added to the registry in future documents if necessary.
