Last Call Review of draft-ietf-isis-sbfd-discriminator-02
review-ietf-isis-sbfd-discriminator-02-opsdir-lc-dodge-2015-11-19-00

Hello,

I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written with the intent of improving the operational aspects of
the IETF drafts. Comments that are not addressed in last call may be included
in AD reviews during the IESG review.  Document editors and WG chairs should
treat these comments just like any other last call comments.

This intended status of this document is Standards Track.

This document defines a new sub-TLV of the IS-IS Router Capability TLV to
advertise one or more S-BFD Discriminators.

NITS

====

The NITS Tool founds the following warnings:

 == The document seems to contain a disclaimer for pre-RFC5378 work, but was
     first submitted on or after 10 November 2008.  The disclaimer is usually
     necessary only for documents that revise or obsolete older RFCs, and that
     take significant amounts of text from those RFCs.  If you can contact all
     authors of the source material and they are willing to grant the BCP78
     rights to the IETF Trust, you can and should remove the disclaimer.
     Otherwise, the disclaimer is needed and you can ignore this comment.
     (See the Legal Provisions document at

http://trustee.ietf.org/license-info

 for more information.)

 == Outdated reference: A later version (-05) exists of
     draft-ietf-bfd-seamless-base-04

-----------------------------------------

In addition the following sentence may need clarification:

"

When multiple S-BFD discriminators are

advertised how a given discriminator is mapped to a specific use case

is out of scope for this document."

It was not clear to me whether this is defined or will be defined in a
different document or whether this is left open for each implementation.

------------------------------------

Other than the above, I have no issues with the document.

Thank you kindly,
