Informational

Document describes how an implementation my use TE information and does
not define any protocol related formats and behaviors.

Yes.

This document describes how to use network performance data, such as
is advertised via the OSPF and ISIS TE metric extensions (defined in
other RFCs) to perform path selection based on network performance
criteria.

This document moved from to the TEAS WGs as part of the routing WG
changes.  This document has been fairly noncontroversial.

The extensions defined in this document are compatible with earlier
implementations.  While there have been no public statements on
implementation, the authors are from multiple vendors, and
implementation is expected - or may even already exist.

The Document Shepherd has reviewed the document as part of an extended
WG last calls.  The Shepherd believes this document is ready for

No.

No.

No specific concerns.

Yes, see thread at

OLD: No IPR disclosed. 
NEW:  IPR disclosed, see https://datatracker.ietf.org/ipr/2200/

Note that per the authors:

> I'm not aware of any IPR that applies on this draft.

> IPR related to TLVs introduced in draft-ietf-isis-te-metric-extensions and RFC7471 have been disclosed already in compliance with IPR rules.

Solid among those who are interested. "strong concurrence of a few
individuals, with others being silent" is a reasonable
characterization.

No discontent seen.

The document passes ID nits.

Yes.

No.

No.

No.

The IANA section was fully reviewed by the document shepherd and is
appropriate for an Informational draft.

None.
