OPS-DIR review: Status: Ready with nits General comment: Well-written, concise, and clear. The authors did excellent work. NITS - in the error handling (sections 7.2, 7.3, and 7.3) 1. section 7.2, paragraph 3, last sentence starting "Such a PCC" Old/Such a PCC MAY decide to utilize the capability even though it did not advertise support for it./ It seems as though PCC in this sentence is a typographical error for PCE. 2. section 7.2, sentence 2, It is unclear what happens if the "MAY clause is taken". Does the Stateful PCE simply report success or is it silent or does the error report get made? Current text:/ If no LSP state information is available to carry out re-optimization, the stateful PCE SHOULD report the error "LSP state information unavailable for the LSP re-optimization" (Error Type = 19, Error value= TBD6), although such a PCE MAY consider the re-optimization to have successfully completed./ 3. section 7.3. sentence 5, beginning "An implementation May choose to" text: /An implementation MAY choose to ignore the requested exclusion when the LSP cannot be found because it could claim it that it has avoided using all resources associated with an LSP that doesn't exist./ Does the implementation send an error report in this case or does it positively ack the response? The MAY clauses lack clear actions. Thanks for your hard work on this document.
