Dear OPSAWG colleagues, First of all, lots of thanks for the inputs on the mailing list and the discussions among authors and contributors. You can find the new version for your review and feedback in: https://tools.ietf.org/html/draft-ietf-opsawg-l3sm-l3nm-01
Let me summarize the main changes bellow: * Editorial issues from Tom Petch's review fixed ( see https://www.mail-archive.com/opsawg@ietf.org/msg03834.html ) * Implementations added (Thanks Huawei, Infinera and Nokia for providing feedback). Please, if you are aware of other implementations and are willing to share, please email authors and the reference to the implementation will be incorporated. * New contributors: We welcome Med Boucadair and Stephane Litkowski, both providing their great expertise in L3 VPNs and experience from the L3SM work. * Changes from “site-centric” view to “network-centric” view. - Old hierarchy: main containers vpn_service, site and vpn_profiles. Under site, list of site_network_access. - New hierarchy: only vpn_services and vpn_profiles. Under vpn_service, vpn_nodes and under vpn_nodes vpn_network_access - Site disappears as it is an information relevant for the service orchestration which consumes l3sm. In this model, aimed at managing vpn services in a network controller, the site is not needed. - With the new model hierarchy, the yang module is easier to use. A vpn service with several vpn-network-accesses can be created in a single call. * Examples: A examples section has been added to understand how the model can be used. In this version, authors have started by including a simple, but widely used in Service Providers, example. Future versions will include more complex examples. * Terminology: In order to help readers understand correctly the model, the terminology section has been revisited and completed. * Yang model Prune: All customer related parameters that are not necessary for the vpn service creation have been removed. For example, location info is removed, as the module is used when the PE selection is already done. Also, unused containers coming from L3SM are removed. * Process ID in OSPF added. * Description of the Yang model: The description of the model has been extended in order to allow implementors and users of the model to understand its use and avoid unambiguities. Please, let us know if you find any part unclear and needs further explanations, we would be glad to add them. * Relation with other Yang models. This section points which models are related to l3nm. L3SM, the model used to interact with the customer, is mentioned. Also, IETF network, which can contain the list of PEs of the Service Provider Network is mentioned. Also, the model will provide inputs for device configuration models used to implement the L3 VPN Service creation intent. * Security section completed. Potential threats from malicious or unauthorized clients are identified. * References have been updated and reorganized between normative and informative. Looking forward to you review and comments.

This draft is a work item of the Operations and Management Area Working Group WG of the IETF. Title : A Layer 3 VPN Network YANG Model Authors : Alejandro Aguado Oscar Gonzalez de Dios Victor Lopez Daniel Voyer Luis Angel Munoz Filename : draft-ietf-opsawg-l3sm-l3nm-01.txt Pages : 99 Date : 2019-11-17 Abstract: RFC8299 defines a L3VPN Service YANG data Model (L3SM) that can be used for communication between customers and VPN service providers. That data model plays the role of a Customer Service Model, according to the terminology defined in RFC8309, and is as such adequate for service negotiation and order handling matters. There is a need for a more network-centric YANG data model to be used in the communication between the entity that interacts directly with the customer, the service orchestrator, (either fully automated or a human operator) and the entity in charge of network orchestration and control (a.k.a., network controller/orchestrator). This document specifies a L3VPN Network YANG Model (L3NM) to facilitate communication between a service orchestrator and a network controller/orchestrator. Such data model provides a network-centric view of the L3VPN services. The Yang model proposed is limited to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364.
