    It might helpful to note that some IETF protocol YANG models choose to put their interface configuration under the protocol rather than under the interface.
    
    E.g. https://tools.ietf.org/html/draft-ietf-isis-yang-isis-cfg-42
    
    All of the ISIS interface configuration (e.g. described in section 2.4) lives under the isis protocol instance rather than the top level "/if:interfaces/..." tree.
    
    I've not checked, but would expect for OSPF, BGP, L2VPN, etc to be modelling similarly.

Yes. 
    
    This would obviously be a bigger change to make to the 802.1Q YANG model, but I just wanted to make you aware of this alternative modelling option.

Right - since the scope of the protocol is a bridge domain (as opposed to a single interface), this would make sense. 

Thanks,
Acee

    
    Thanks,
    Rob
