Informational

The document explores different approaches for handling SR and
RSVP-TE coexistence, and then concludes with a preferred approach.
I think it stops short of a required approach, which would make
BCP more appropriate.

> Is this type of RFC indicated in the title page header?

Yes.

   The document provides solution options for keeping the traffic
   engineering database (TED) consistent across the network,
   accounting for the different bandwidth utilization between SR
   and RSVP-TE.

Don't think there is anything particularly noteworthy.

This is an informational document that has fairly niche
interests.  I think it has been adequately discussed in the WG
although I would certainly have preferred greater review and
participation.

The shepherd reviewed the document multiple times as it progressed
through the WG as well as conducted a final shepherd review.  This
review yielded some minor comments that have been sent to the authors.

No.

No

None.

Yes.

The working group was made aware of the IPR prior to WG adoption
and was reminded of the IPR (via a pre WG LC Poll) before LC.  No
other comments were made by WG participants.

Yes, a reference to draft-ietf-spring-segment-routing is
normative.  This draft is being managed by the SPRING WG.  Frankly
this reference could be made informative as the whole document is
informative, but I also don't see an issue with the publication of
this draft being blocked by the reference either.

No.

No, N/A.

As an informational document without protocol changes, there is no
IANA impact.
