[spring] Re: Shepherd review for draft-ietf-spring-bfd-10

[Greg Mirsky <[e-mail]>]

Hi Alvaro,
thank you for your thoughtful and helpful suggestions. Please find my notes
below tagged GIM>>. I've included the diff to highlight the updates applied
in the new working version (somehow, idnits missed another outdated
reference).

Regards,
Greg

GIM>> I've used it, and now the section reads as follows:
NEW TEXT:
   This document describes the specifics of using MPLS LSP Ping, BFD,
   and BFD for multipoint networks for the Segment Routing network with
   the MPLS data plane.  Since all the discussed tools have been used in
   MPLS networks, there are no additional security risks.  Security
   considerations discussed in [RFC5880], [RFC5884], [RFC8562],
   [RFC8563], [RFC7726], [RFC8029], and [RFC9256] apply to this
   document.

GIM>> I propose the following new section:
11.  The Scope of the Experiment

   The experimental part included in this document is limited to the use
   of Non-FEC Path TLV in BFD Reverse Path TLV [RFC9612].  The goal of
   the experiment with the Non-FEC Path TLV is validation that its use
   does not adversely affect the defect detection in the forward
   direction while reducing the number of used BFD sessions between a
   pair of LSRs without reporting additional false-negative events.
