Hi,

my main objection against this draft is that is completely bypasses the core routing data model.

I understand that it is easier to map the logic of a vendor-specific configuration to a YANG module that is built from scratch, but then we might end up with several alternative data models for each routing protocol.

One of the objectives stated in the routing-cfg document is that the routing data model should enable mapping of proprietary data models. And indeed, throughout the development of the core routing data model we always tried to allow for such mappings, at least for the major router implementations. 

There is nothing wrong on using YANG for expressing proprietary data models but IMO the data models developed and standardised in the IETF should be vendor-neutral and should serve as a lingua franca to which the proprietary models can be mapped (and vice versa).
