Hi,

I don't think you can assume all deployemnts use one vendor's tools
just because there are no standard PIBs.
My research showed support in the Juniper/Netscreen products, and in
Huawei/HuaweiSymantec products.
I have no reason to believe all deployments use exclusively one or the
other's tools or PIBs.

It is safe to assume they may not interoperate across vendor
implementations, if that was your point. But that is our fault, when
we as a community decided not to allow PIBs onto the standards-track,
and effectively told the COPS-PR developers to just go home.

In the absence of standard YANG models, any netconf deployments are
not all based on one vendor's tools.
In the absence of standard YANG models, the Netconf deployments using
equipment from different vendors and vendor-specific data models are
also not interoperable. 

Is that the point you wanted to make? That interoperability is
hindered by not having standards-track models?
