Hi Lada, NETMOD, 

So I think we should move forward this ietf-rtg-cfg so that it can be
augmented and other work can move forward. We are still in disagreement
with respect to routing-instance/interface configuration.

    - We feel the IPv4/IPv6 interfaces should reference the
routing-instance in their config state. This is consistent with
draft-rtgyangdt-rtgwg-device-model-01.txt.
    - You feel that the routing-instance should have a list of leaf-ref’s
to the interface. You believe the leaf-ref provides a level of validation
due to the fact that references can be confined to routing-instance
references. However, heretofore, no models are referencing the interface
leaf-refs in the list.

Other than the Routing YANG Design Team having chosen the first option -
are there any other opinions?

Thanks,
Acee
