Job and Robert: 


If you wish to pick draft-ietf-idr-opertional-messages-00.txt , just resubmit with a new version.  


If you have 2 implementations, we can push this quickly toward publication.

Perhaps this work should be picked up again.

Just to refresh memory there is an active WG document precisely describing how to carry such information between BGP peers. It is called BGP Operational Message 


The ADVISE TLV there section 3.4.1 and 4 are proposed with the very same intention as this discussion is targeting. 


Due to no customer push vendors have not implemented it yet. So the draft is just hanging waiting for implementations.  


I think if there is some new interest please consider to review the linked WG doc and possibly augment it with missing elements. 


Use of BGP capabilities in current state of implementation of bgp dynamic capabilities is really not the right messaging vehicle here.

Right now operators use the peer’s MAC address and certain TCP behaviorism (nmap -O) to attempt to conclude what the remote side might be in case of issues. 


I see value in having this on by default. Security through obscurity isn’t the best defense anyway. I’m assuming a degree of trust exists anyway, why else set up a BGP session in the first place?


I think there are valid use cases, i think it is worthwhile exploring how to implement this concept.


Kind regards,
