Hi Stephen

Many thanks for this comment.  I'm picking up this thread and replying as PCE working group chair, as the authors are unavailable.  I apologise for the delay.

Please see my proposed resolutions inline below, marked with "Jon>"

COMMENT:
----------------------------------------------------------------------

In 10.1, some references seem to be needed to say how to do that authentication and encryption. IIUC, that's a work in progress, or is that right? If so, when's it likely to be done and usable?

Jon> You are correct - this is being specified in draft-ietf-pce-pceps.  That document is ready to be submitted to the IESG (we are only waiting for the IPR poll to conclude) but draft-ietf-pce-stateful-pce is likely to be published first.
We already discussed how to handle this with draft-ietf-pce-stateful-sync-optimizations, which was approved for publication recently.  I think that we should handle it in a consistent way for draft-ietf-pce-stateful-pce.  So I propose this change:

OLD
   As a general precaution, it is RECOMMENDED that these PCEP extensions
   only be activated on authenticated and encrypted sessions across PCEs
   and PCCs belonging to the same administrative authority.
NEW
   As a general precaution, it is RECOMMENDED that these PCEP extensions
   only be activated on authenticated and encrypted sessions across PCEs
   and PCCs belonging to the same administrative authority, using Transport Layer
   Security (TLS) [I-D.ietf-pce-pceps], as per the recommendations and
   best current practices in [RFC7525].  An administrator could also expose the
   speaker entity id as part of the certificate, so that the peer's identity can be verified.
END NEW
