It is the latter, the basic BGP YANG model.

Qin:

Just to make sure I have the context, the “BGP model” is the 
draft-bess-l3vpn-yang-draft or the base BGP protocol model?

Subject: [bess] miss import and export policy within routing-policy under 
vpn-target


Hi, folks:

When I walk through draft-ietf-bess-l3vpn-yang draft today,

I see what is missing in routing policy model is import and export policy 
parameter, the grouping apply-policy defined in routing policy yang model which 
supports import and export policy is not used in the BGP model,

So I am wondering why we not add import and export policy and take out routing 
policy leafref.

Also I am wondering whether all the vendors support import-from-global and 
export-to-global, if the answer is no,

I am wondering if we should add if-feature for import-from-global and 
export-to-global and take them completely out.
