   This document sets out the problem statement and architecture for the
   exchange of TE information between interconnected TE networks in
   support of end-to-end TE path establishment. It describes how
   existing RFCs can be used to establish an end-to-end TE path with a
   set of constraints (such as bandwidth) across one or more network
   from a source to a destination.

This document has been in process for a long time.  There were many
heated discussions that eventyually led to the this document which has a
high degree of support.  Recent delays were largely editorial rather
than in content.

This document has been discussed and reviewed by the WG many times.  It
has a wide scope and covers it comprehensively.  Having this information
consolidated in a single place has real value to the WG, users and
vendors.

No.

No concerns.  The document is in good shape for publication.

Yes.

Yes.

The IPR was discussed and the last messages on the topic stated:
1. https://www.ietf.org/mail-archive/web/teas/current/msg01038.html
   IPR was disclosed as required
2. https://www.ietf.org/mail-archive/web/teas/current/msg01037.html
   IPR on "BRPC" was also disclosed on RFC5441, back in 2007.

IMO strong concurrence.

No.

The document has one idnits warning (a long line).

> (12) Describe how the document meets any required formal review
> criteria, such as the MIB Doctor, media type, and URI type reviews.
> 

No formal review required/appropriate.

> (13) Have all references within this document been identified as

> 

yes (although all marked as informative)

> (14) Are there normative references to documents that are not ready for
> advancement or are otherwise in an unclear state? If such normative

> 

No.


> (15) Are there downward normative references references (see RFC 3967)?
> If so, list these downward references to support the Area Director in 
> the Last Call procedure. 

No.

No, N/A.

This document describes how exsiting RFCs can be used so there are no
new IANA considerations.

None.

> 
> 

None needed.
