Summary: The document is almost ready for publication as a standards 


track RFC, but has some minor issues that should be fixed.






I reviewed version -06 of this document. At that time I had a few 


comments. Most of them have been successfully addressed. In this review I 


am addressing the leftovers and new issues.




Major issues: none

Minor issues:



- In my previous review, I highlighted that many lowercase 2119-reserved 


words (like "must", "may", etc.) should actually be written in uppercase 


to be really normative. Rather than analyzing each case on a one by one 


basis, the authors have systematically written in uppercase all 


2119-reserved words. The problem is that now some uppercase 2119-reserved 


words don't make sense, and should be reverted to lowercase. Allow me 


some examples:






  * Sections 1 (Introduction) and 2 (Motivation and Scope). Since these 


are descriptive sections in nature, normative text should not be written 


here. If there is a need to write normative text, it should be written 


later in any of the procedures sections.






  * Section 5.2, 1st paragraph, the "MUST" does not really have a 


normative intention as it is currently written:




   One endpoint node of the redundant set of PWs is designated the
   Master and is responsible for selecting which PW both endpoints MUST
   use to forward user traffic.



  * Section 15.2. I understand that this section describes scenarios or 


examples of architectures. Therefore, it does not make sense to write 


normative statements in here. If you need one, it should be written in 


any of the procedures sections. There is a "SHOULD" on the 4th paragraph 


of Section 15.2. The same applies to the last paragraph in Section 15.4 


and last paragraph in Section 15.6.







Nits/editorial comments:



- The abstract has added a new sentence at the end. Unfortunately there 


is a new reference "in RFC 5542 [9]". Abstracts shouldn't include 


references. Just write "... in RFC 5542".






- There is an extra dot at the end of the second paragraph in Section 


6.1. The same happen in the last paragraph of Section 15.3. And yet the 


same in the third paragraph of Section 15.4, and the second paragraph in 


15.6.




- Section 15.4, second paragraph, the term "Figure" is repeated.

- Section 15.5, the last paragraph starts with some strange indentation.
