Hi Thomas,
Thanks for your review. You hit the nail on the head!
We had an extended conversation yesterday with Luuk precisely on this
point -- the draft of the -00 did include this possibility, the final
-00 does not; we went for considerations for simplicity and today it is
one point on which i'd have asked for feedback during the WG. So, yeah,
if there is interest in this direction, we can open that door and review
how summaries at the exporter and at the station can interplay.

Dear Paolo and authors,
Thanks a lot. I just reviewed the document and find it for a network operators,
operating network analytics stacks, very useful.
The document abstract describes the aim of the document. Targeting the use case
of offline BMP data processing and in section 3 describing that the new BMP
message type is originated at the BMP monitoring station, data collection.
I believe another very common use case can be covered as well. As stated, it is
very common that BGP peerings are very stable and peering state informations
might not persisted in a time series databases with limited data retention.
Have regular refreshes on BGP peering states is therefore very helpful.
Avoiding that the BGP peering state expires in the time series database due to
retention policy. In my opinion, these regular BGP peering state refreshes
could not only be originated from the BMP monitoring station, but also from the
router. This avoids that the BMP monitoring station needs to cache, store the
BMP message type peer_up in order to track the state of the BGP peering as
described in
https://datatracker.ietf.org/doc/html/draft-lucente-grow-bmp-offline-00#name-operational-considerations.
If you agree that Peer Summary messages can be originated from the router as
well, we want to consider the enablement and frequency to be configurable
through https://datatracker.ietf.org/doc/html/draft-ietf-grow-bmp-yang and
update draft-lucente-grow-bmp-offline with the use case an possibility to
originate Peer Summary messages from the router.
Best wishes
Thomas

Dears,
A brief email to say about this initial effort we have just posted to make BMP
more off-wire friendly. I will briefly present around this at the Grow session
tomorrow. Appreciate as always thoughts, reviews and tomatoes.

Abstract:
BMP (BGP Monitoring Protocol) [RFC7854] is perfectly suited for real-
time consumption but less ideal for off-wire historical purposes.
The main issue is the dependence that parsing BGP Update PDUs has on
knowing which capabilities have been agreed when establishing the BGP
session with the peers, which could have happened long time ago
(days, weeks, months).
This document defines a new optional BMP message type, called Peer
Summary, that carries a summary of the established BGP sessions along
with their capabilities and that is intended to be injected in the
BMP feed at configurable time intervals and/or ad-hoc whenever it is
felt necessary to improve fruition of BMP data offline.
