[Idr] Re: New Liaison Statement, "oLS to IETF on BGP data model"

[[e-mail]]

Hi Adrian and all,
Yes, it would be mutually beneficial for BBF provide implementation information to IETF.
I am currently discussing this with BBF leadership to identify member companies who have deployed the bgp data model. If any implementations are found (we hope so), I will encourage them to share their information directly with IETF IDR or provide it through a follow-up liaison. Will keep you updated on any progress.

Best regards,
Xueyan (BBF Liaison Manager)

I woner whether the BBF, being all enthusiastic, could supply us with any implementation information.
 
(Obviously, fixing the YANG is important for us and the BBF.)

Hello All, 
  
The BGP-4 YANG model document has gone through WGLC and has been waiting for implementations for more than 2 years now. I am not sure of its current status - I do see warnings and errors being reported on the YANG.
 
All 3 IDR chairs are authors on it and the IDR Secretary is the document shepherd. I recognize this odd situation. However, a decision on the future of this document is now overdue. This Liaison is a good trigger for the WG to make a decision (and within a timeframe so the Liaison can be responded to).
 
As AD, I've already expressed my view that an exception to the 2 implementation rule be sought from the WG for this document so it can be published as an RFC. I believe it was in Madrid where I had expressed that view, but perhaps even before that. If there is consensus to proceed with that exception, this can be progressed - else it just stays waiting for implementation and the WG will need to give a suitable response to BBF.
 
Sue, Jeff, Keyur, and Jie, could you please take this topic up as a priority request from me for discussion at your next meeting? Please let the WG know your thoughts and if there is anything that you would like me to do, please let me know.
 
Thanks,
Ketan

Body: Dear Colleagues, 
 
Broadband Forum is currently working on defining protocols, message flows and data models for disaggregated devices. In particular, Provider Cloud Work Area is working on Disaggregated Access Node, namely TR-477, and in the second release of it, currently on draft, it is focusing on the disaggregation of L3 functions. Obviously, apart from creating the CP-UP message flows for the disaggregated functions, BBF is not developing any new data models, if they already exist in other SDOs. One of the L3 functions currently under development is BGP and BBF is reusing the current draft data model developed by IETF: 
 
•       draft-ietf-idr-bgp-model-18 
link: draft-ietf-idr-bgp-model-18 - YANG Model for Border Gateway Protocol (BGP-4) 
 
of which we are only using the following data model: [e-mail]. 
 
The BBF document referring to this data model (WT-477i2) is almost completed, and we are going to proceed with our straw ballot process. Anyhow we cannot proceed with the publication until the IETF data model on BGP is published. 
 
So, we would like to ask if the IETF have any target publication dates for the data model mentioned above in order to understand when we can publish the issue 2 of TR-477. 
 
 
Sincerely, 
 
Lincoln Lavoie, 
Broadband Forum Technical Committee Chair
