Hi, stephane:

It seems that the current version of the Yang Model is more
structured/moduled and organized reasonable. 

Here I have some questions for the revised version:
1. What is the scenario where the leaf "customer-nat-address" will be used?
If the customer being provided one public address, why use NAT? if use NAT,
why allocate such "customer-nat-address"?
2. What is the main reason that define grouping "vpn-svc-cfg"? you have
defined grouping "site-service-mpls", "site-service-multicast" etc. Is it
possible to define for example "site-service-cloudaccess" and use them later
directly within the container "l3vpn-svc"?
3. There are some overlapping contents between grouping
"site-attachment-ip-connection" and
"site-customer-routing-specific-information", and the latter is more vague
and hard to understand. Can it be merged into the grouping
"site-attachment-ip-connection"?

Hi WG,

Here is a new version of our draft fitting some comments received on the
list or during IETF meeting.
- First level of modularization has been done , is it enough ?
- Site templates putted as a separate list
- More abstracted VPN policy and removal of native VPN
- Add MPLS leaf in vpn-svc for the CsC case
- some renaming
...

Multicast comments are not addressed yet.

Please provide your comments on this new proposal.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
 This draft is a work item of the L3VPN Service Model  Working Group of the
IETF.

        Title           : YANG Data Model for L3VPN service delivery

Abstract:
   This document defines a YANG data model that can be used to deliver a
   Layer 3 Provider Provisioned VPN service.  The document is limited to
   the BGP PE-based VPNs as described in RFC4110 and RFC4364.  This
   model is intended to be instantiated at management system to deliver
   the overall service.  This model is not a configuration model to be
   used directly on network elements.  This model provides an abstracted
   view of the Layer 3 IPVPN service configuration components.  It will
   be up to a management system to take this as an input and use
   specific configurations models to configure the different network
   elements to deliver the service.  How configuration of network
   elements is done is out of scope of the document.
