Reviewer: Roni Even Review Date: 2019-04-14 IETF LC End Date: 2019-04-15 IESG Telechat date: Not scheduled for a telechat Summary: The document is almost ready for publication as a standard track RFC. Major issues: Minor issues: 1. In section 1.1 last bullet does it mean that you MUST NOT use H-PCEP on the internet? 2. In section 3.2.1 or section 4.1 if the originator sends PCC or PCE sends an open with P flag =0 can the response open be sent with a P flag =1 and if yes what should be the action of the originator. I did not see any text about this case. Nits/editorial comments: 1. in section 1 "achild" should be " a child" 2. Section 2.4 repeat some of the text from RFC6805 1.3.2.2 but using different sentence structure. Is there a reason to change the wording.
