Summary:  Ready for publication.


Should this document be an update to the MPLS-TP Framework (RFC 5921)?
I am not sure.  RFC 5921 does make it clear that it covers only point-
to-point transport paths.  The answer may be further complicated by
the fact that RFC 5921 is joint work with the ITU-T.

Major Concerns:  None.

Minor Concerns:  None.

Other Comments:

In the first sentence of Section 1, please define MPLS-TP as follows:
   The Multiprotocol Label Switching Transport Profile is the ...
   The Multiprotocol Label Switching Transport Profile (MPLS-TP) is ...

Please add TE-LSP to the terms defined in Section 1.2.

In Section 5.1, I cannot understand this sentence:
>  Per [RFC6373], the definitions of P2MP, [RFC4875], and GMPLS
>  recovery, [RFC4872] and [RFC4873], do not explicitly cover their
>  interactions.
I think that the references are getting in the way.  I think the
message is: "the definitions of P2MP and GMPLS recovery do not
explicitly cover their interactions."  If I am correct, then some
commas need to be removed.

The phrase "MPLS Transport Profile" appears many places, and it would
be easier if they were replaces with "MPLS-TP" for consistency.
