I have performed an Operations Directorate review of
	draft-ietf-pce-pcep-inter-domain-p2mp-procedures-06



Sorry for this arriving late.. I do not claim expertise on the specific 


topic this I-D covers, so treat the "substantial comments" according to 


that.




** General:



I found the document sound and well written. Although the writing style 


is referencing related documentation as much as possible without 


repeating any text from them makes the document short, it also makes 


reading the document somewhat a taunting task unless the reader can 


memorize all the related & referenced RFCs. I am not asking anything on 


this regard, just pointing it out.




** Editorials:

Abstract:



o I would expand all non-obvious acronyms and not use acronyms at all 


unless the acronym in already non-expandable 


(

http://www.rfc-editor.org/rfc-style-guide/abbrev.expansion.txt

)




o Section 7.2 bullet 4
  s/step3/step 3

o Section 7.2.
  Acronym S2L has two different expansions "Source-to-Leaf" and
  "Source to Leaf BN". Would be less confusing to use one.

o Section 7.2.
  s/, Etc./, etc.

o Section 7.2:
  Is the "\" in the "\prod" intentional?


** Substantials:

o Section 7.4.1.
  A small nit.. I somehow would like to see this document actually
  showing the value of the new IANA allocated C-bit in the RP
  Object Flag Field. Now there is going to only be a reference to
  the IANA registry.

o Section 7.4.2.
  The I-D references to H-PCE for the dynamic discovery of the
  domain-tree. According to the RFC6805 one valid solution for
  H-PCE PCE child-parent discovery is also static configuration..
  So I might reconsider the word "dynamically" in this section.


** Operationals:

o I actually found it surprising that the document already had put
  thought on the operational and management aspects. Well done ;)

o I would add a note into Section 9 again emphasising the fact that
  preconfiguring and maintaining domain-trees might be a considerable
  administration effort.
