Hello Robert, Thanks for providing the pointer on the BGP Operation Message Draft. We looked through it. In this draft, Operational message is defined to carry different types of Operational TLVs like: ADVISE, STATE, DUMP and CONTROL and trying to provide network operational data between the BGP nodes.
The draft we proposed has a different purpose. It doesn’t exchange BGP operational data between the BGP nodes. Rather it defines on how to send BGP feedback information for a prefix to notify the network inconsistency to the BGP originator. The current use cases are in the BGP Segment Routing application as described in the draft.

For starter can you elaborate if you conisdered to just add SR related information to BGP Operational Message as defined before in https://tools.ietf.org/html/draft-ietf-idr-operational-message-00 ? Kind regards, Dave, Robert & Rob.

Name: draft-deevimajumdar-spring-bgp-feedback Revision: 00 Title: A Framework for BGP Feedback Message In Segment Routing Document date: 2017-04-21 Group: Individual Submission Pages: 12 URL: https://www.ietf.org/internet-drafts/draft-deevimajumdar-spring-bgp-feedback-00.txt Status: https://datatracker.ietf.org/doc/draft-deevimajumdar-spring-bgp-feedback/ Htmlized: https://tools.ietf.org/html/draft-deevimajumdar-spring-bgp-feedback-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-deevimajumdar-spring-bgp-feedback-00 Abstract: In support of Segment Routing(SR), routing protocols advertise a variety of identifiers used to define the segments that direct packet forwarding. In cases where the information advertised by a given protocol instance is either internally inconsistent or conflicts with advertisements from another protocol instance a means of notifying the originator about the inconsistency is required. This document defines a generic mechanism to notify the BGP originator about the inconsistency in the network. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
