Liaison statement
oLS to IETF on BGP data model

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: ietf-bgp@2024-10-21.yang.

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
