Introduction YANG [RFC6020] is a data definition language that was introduced to define the contents of a conceptual data store that allows networked devices to be managed using NETCONF [RFC6241]. YANG is proving relevant beyond its initial confines, as bindings to other interfaces (e.g. REST) and encoding other than XML (e.g. JSON) are being defined. Furthermore, YANG data models can be used as the basis of implementation for other interface, such as CLI and Programmatic APIs. This document defines a YANG data model that can be used to configure and manage Multicast in MPLS/BGP IP VPN (MVPN). It includes Cisco systems' solution [RFC6037], BGP MVPN [RFC6513] [RFC6514] etc. Currently this model is incomplete, but it will support the core MVPN protocols, as well as many other features mentioned in separate MVPN RFCs. In addition, Non-core features described in MVPN standards other than mentioned above RFC in future version.

Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC-2119 [RFC2119]. 1.2. Terminology The terminology for describing YANG data models is found in [RFC6020]. This draft employs YANG tree diagrams, which are explained in [I- D.ietf-netmod-rfc6087bis]. 2. Design of Data model 2.1. Scope of model The model covers Rosen MVPN [RFC6037], BGP MVPN [RFC6513] [RFC6514]. The representation of some of extension features is not completely specified in this draft of the data model. This model is being circulated in its current form for early oversight and review of the basic hierarchy. The operational state fields of this model are also incomplete, though the structure of what has been written may be taken as representative of the structure of the model when complete. This model does not cover other MVPN related protocols such as MVPN Extranet [RFC7900] or MVPN MLDP In-band signaling [RFC7246] etc., these will be covered by future Internet Drafts. 2.2. Optional capabilities This model is designed to represent the capabilities of MVPN devices with various specifications, including some with basic subsets of the MVPN protocols. The main design goals of this draft are that any major now-existing implementation may be said to support the basic model, and that the configuration of all implementations meeting the specification is easy to express through some combination of the features in the basic model and simple vendor augmentations. On the other hand, operational state parameters are not so widely designated as features, as there are many cases where the defaulting of an operational state parameter would not cause any harm to the system, and it is much more likely that an implementation without native support for a piece of operational state would be able to Liu & Guo, etc Expires January 3, 2018 [Page 3] Internet-Draft MVPN Yang Model July 2017 derive a suitable value for a state variable that is not natively supported. For the same reason, wide constant ranges (for example, timer maximum and minimum) will be used in the model. It is expected that vendors will augment the model with any specific restrictions that might be required. Vendors may also extend the features list with proprietary extensions. 2.3. Position of address family in hierarchy The current draft contains MVPN IPv4 and IPv6 as separate schema branches in the structure. The reason for this is to inherit l3vpn yang model structure and make it easier for implementations which may optionally choose to support specific address families. And the names of objects may be different between the IPv4 and IPv6 address families. 3. Module Structure 3.1. MVPN Configuration The MVPN modules define the network-instance-wide configuration options in a two-level hierarchy as listed below: Instance level: MVPN configuration attributes for the entire routing instance, including route-target, I-PMSI tunnel and S-PMSI number, common timer etc. PMSI tunnel level: MVPN configuration attributes applicable to the I-PMSI and per S-PMSI tunnel configuration attributes, including tunnel mode, tunnel specific parameters and threshold etc. Where fields are not genuinely essential to protocol operation, they are marked as optional. Some fields will be essential but have a default specified, so that they need not be configured explicitly. The module structure also applies, where applicable, to the operational state as well. Our current direction is to agree to a network-instance-centric (VRF) model as opposed to protocol-centric mainly because it inherits l3vpn and it can as a part of l3vpn yang model.
