Introduction YANG [RFC6020] [RFC7950] is a data definition language that was introduced to model the configuration and running state of a device managed using network management protocols such as NETCONF [RFC6241]. Liu, et al. Expires April 24, 2018 [Page 2] Internet-Draft PIM YANG October 2017 YANG is now also being used as a component of wider management interfaces, such as CLIs. This document defines a YANG data model that can be used to configure and manage Protocol-Independent Multicast (PIM) devices. This model supports the core PIM protocol, as well as many other features described in Section 2.1. Non-core features are defined as optional in the provided data model. 1.1. 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 BCP 14, RFC 2119 [RFC2119]. 1.2.

Prefixes in Data Node Names In this document, names of data nodes, actions, and other data model objects are often used without a prefix, as long as it is clear from the context in which YANG module each name is defined. Otherwise, names are prefixed using the standard prefix associated with the corresponding YANG module, as shown in Table 1. +----------+--------------------+-----------------------------------+ | Prefix | YANG module | Reference | +----------+--------------------+-----------------------------------+ | yang | ietf-yang-types | [RFC6991] | | inet | ietf-inet-types | [RFC6991] | | if | ietf-interfaces | [I-D.bjorklund-netmod-rfc7223bis] | | rt | ietf-routing | [I-D.acee-netmod-rfc8022bis] | | rt-types | ietf-routing-types | [I-D.ietf-rtgwg-routing-types] | +----------+--------------------+-----------------------------------+ Table 1: Prefixes and Corresponding YANG Modules 2. Design of Data Model 2.1. Scope of model The model covers PIM Sparse Mode [RFC7761], including the Source- Specific subset [RFC3569] [RFC4607], Dense Mode [RFC3973], and Bi- directional PIM [RFC5015]. The PIM extensions represented in the model include BSR [RFC5059] and Anycast-RP [RFC4610]. The data model can be used to configure and manage these protocol features. The operational state data and statistics can be retrieved by this model. The protocol specific notifications are also defined in the model. This model does not cover other multicast protocols such as IGMP/MLD, MSDP, mVPN, or mLDP in-band signalling. It does not cover any configuration required to generate the MRIB. These will be specified in separate documents. 2.2. Optional capabilities This model is designed to represent the capabilities of PIM devices with various specifications, including some with basic subsets of the PIM protocol. The main design goals of this draft are that any major now-existing implementation may be said to support the base model, and that the configuration of all implementations meeting the Liu, et al. Expires April 24, 2018 [Page 5] Internet-Draft PIM YANG October 2017 specification is easy to express through some combination of the features in the base model and simple vendor augmentations. There is also value in widely-supported features being standardized, to save work for individual vendors, and so that mapping between different vendors' configuration is not needlessly complicated. Therefore, these modules declare a number of features representing capabilities that not all deployed devices support. The extensive use of feature declarations should also substantially simplify the capability negotiation process for a vendor's PIM implementation. 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 derive a suitable value for a state variable that is not natively supported. For the same reason, wide constant ranges (for example, timer maxima and minima) will be used in the model. It is expected that vendors will augment the model with any specific extensions and restrictions needed to adapt it to their vendor specific implementation. 2.3. Datastore applicability This model conforms to the Network Management Datastore Architecture (NMDA) [I-D.ietf-netmod-revised-datastores]. The operational state data is combined with the associated configuration data in the same hierarchy [I-D.ietf-netmod-rfc6087bis]. 2.4. Top-level structure This model defines several separate modules for modelling PIM configuration, defined below. Again, this separation will make it easier to express the specific capabilities of a PIM device. The hierarchy of PIM configuration is designed so that objects that are only relevant for one situation or feature are collected in a container for that feature. For example, the configuration for PIM- SM that is not relevant for an SSM-only implementation is collected in an ASM container. 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 they need not be explicitly configured. Liu, et al. Expires April 24, 2018 [Page 6] Internet-Draft PIM YANG October 2017 This module structure also applies, where applicable, to the operational state and notifications of the model. 2.5. Position of address family in hierarchy This document contains address-family as a node in the hierarchy multiple times: both under the interface list, and under the PIM instance. This is similar to other protocol Yang models such as IS- IS. The reasoning for this is to make it easier for implementations in which configuration options are not supported for specific address families. For these implementations, the restriction that interface configuration must be address-family independent MAY either be expressed as a vendor augmentation of an address-family-independent parameter above the address-family level, or by a constraint on the base model objects of a form similar to: must ". = ../../address-family[address-family='ipv4']/dr-priority" { error-app-tag "dr-priority-mismatch"; error-message "Error: IPv6 DR priority must match IPv4 DR priority."; } 3. Module Structure 3.1. PIM base module The PIM base module defines the router-wide configuration options not specific to any PIM mode, and is included by the other modules. There are a couple of things worth mentioning here regarding where the PIM model fits in the overall routing hierarchy [I-D.acee-netmod-rfc8022bis]: 1. This data model agrees to a routing-instance-centric (VRF) model view as opposed to protocol-centric mainly because it fits well into the routing-instance model, and it is easier to map from the VRF-centric to the protocol-centric than the other way around due to forward references. 2. The PIM base model augments "/rt:routing/rt:control-plane- protocols" as opposed to augmenting "/rt:routing/rt:control- plane-protocols/rt:control-plane-protocol", as the latter would allow multiple protocol instances per VRF, while the PIM protocol is designed to be enabled or disabled on the per VRF basis.

Implementation Status This section to be removed by the RFC editor. This section records the status of known implementations of the protocol defined by this specification at the time of posting of this Internet-Draft, and is based on a proposal described in [RFC7942]. The description of implementations in this section is intended to assist the IETF in its decision processes in progressing drafts to RFCs. Please note that the listing of any individual implementation Liu, et al. Expires April 24, 2018 [Page 63] Internet-Draft PIM YANG October 2017 here does not imply endorsement by the IETF. Furthermore, no effort has been spent to verify the information presented here that was supplied by IETF contributors. This is not intended as, and must not be construed to be, a catalog of available implementations or their features. Readers are advised to note that other implementations may exist. According to RFC 7942, "this will allow reviewers and working groups to assign due consideration to documents that have the benefit of running code, which may serve as evidence of valuable experimentation and feedback that have made the implemented protocols more mature. It is up to the individual working groups to use this information as they see fit". This document is the work result of the PIM working group's YANG multicast design team. The following wiki page contains the information on the design team members, the meeting discussions, lists of modeled features, and which features are supported by which existing implementations: https://trac.ietf.org/trac/pim/wiki/yang 6. Security Considerations Configuration and state data defined in this document are designed to be accessed via a management protocol with secure transport layer, such as NETCONF [RFC6241]. The NETCONF access control model [RFC6536] provides the means to restrict access for specific users to a pre- configured subset of all available operations and contents. The models defined in this document contain a number of configuration data nodes that are writable, creatable, and deletable. Unauthorised access to the configuration data can adversely affect the routing subsystem of both the local device and the network. This may lead to network malfunctions, delivery of packets to inappropriate destinations and other problems. 7. IANA Considerations RFC Ed.: In this section, replace all occurrences of 'XXXX' with the actual RFC number (and remove this note).
