I do not know what 'we are already on it' means. I am aware of [1] and
it says:
[...] Although this is a concern across the entire scope of YANG
models, this design team is focused on the question of providing
an architecture for the protocols and functionality contained
inside the Routing Area.
I understand that there are valuable discussions in NETMOD that were
triggered by this work of this design team, e.g., how to deal with
virtual (routing) instances. I am less clear when it comes to the
definition of a general 'uebermodel' for network devices that affects
all YANG models (in the IETF or even beyond). Who is charted to define
such a model?
