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"?

Multicast comments are not addressed yet. Please provide your comments on this new proposal. -----Original Message----- From: I-D-Announce [mailto:i-d-announce-bounces@ietf.org] On Behalf Of internet-drafts@ietf.org Sent: Monday, August 03, 2015 13:08 To: i-d-announce@ietf.org Cc: l3sm@ietf.org Subject: I-D Action: draft-ietf-l3sm-l3vpn-service-model-01.txt 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 Authors : Stephane Litkowski Rob Shakir Luis Tomotaki Kevin D'Souza Filename : draft-ietf-l3sm-l3vpn-service-model-01.txt Pages : 94 Date : 2015-08-03 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.
