Introduction YANG [RFC6020] [RFC6087] is a data definition language that was introduced to model the configuration and running state of a device managed using NETCONF [RFC6241]. YANG is now also being used as a component of wider management interfaces, such as CLIs. Liu, et al. Expires November 19, 2016 [Page 2] Internet-Draft PIM YANG May 2016 This document defines a draft YANG data model that can be used to configure and manage Protocol-Independent Multicast (PIM) devices. Currently this model is incomplete, but it will support the core PIM protocol, as well as many other features mentioned in separate PIM RFCs. 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. 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 PIM Sparse Mode [RFC4601], including the Source- Specfic subset [RFC3569], Dense Mode [RFC3973], and Bi-directional PIM [RFC5015]. The PIM extensions represented in the model include BSR [RFC5059] and Anycast RP [RFC4610]. The representation of some of these 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 and notifications 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 multicast protocols such as IGMP/MLD, MSDP, mVPN, or m-LDP in-band signalling. It does not cover any configuration required to generate the MRIB. These will be covered by future Internet Drafts. Liu, et al. Expires November 19, 2016 [Page 3] Internet-Draft PIM YANG May 2016 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 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 restrictions that might be required. Vendors may also extend the features list with proprietary extensions. 2.3. 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. Liu, et al. Expires November 19, 2016 [Page 4] Internet-Draft PIM YANG May 2016 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. This module structure also applies, where applicable, to the operational state and notifications of the model. 2.4. Position of address family in hierarchy The current draft 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 the IS-IS yang draft model. 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 must 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']/ interface[interface=current()/sibling:interface]/dr-priority" { error-app-tag dr-priority-mismatch; error-message "Error: IPv6 DR priority must match IPv4 DR priority "; } 3. Unresolved Issues 3.1. Current status of work in progress The model so far details how the PIM modules interact and covers the higher levels of their hierarchy. Some details of interface configuration, RP configuration, and PIM-ASM-specific parameters are also complete. For a list of the most substantial areas still to cover, please see the "TODO list" section below. 3.2. Group range mappings There is currently no convenient way in the operational state model to map from a group address to the PIM mode and RP information that it will be forwarded according to, which complicates reasoning about the running state and the diagnosis of conflicting policy configuration. Liu, et al. Expires November 19, 2016 [Page 5] Internet-Draft PIM YANG May 2016 A hypothetical group range state reporting object indexed by group range would be desirable for this purpose, but would be inconvenient for many implementations that index the relevant information on RP address (not applicable for DM or unroutable group-ranges), and difficult to express directly in YANG (as it is difficult to express a container indexed on an arbitrary, proprietary policy structure). 3.3. Issues blocked on other model designers Some questions must be resolved with reference to other yang models, and so the resolution may be blocked on a decision from another body. Currently these issues are: 1. The position of BFD in the configuration; does the BFD model augment various different protocols, or do the protocols have to augment themselves individually to support BFD? 2. The abstract concepts of a "set of IP addresses" or "set of IP prefixes", as represented in implementations by prefixes, ACLs or policy statements, is a general concept out of the scope of this document. It will presumably have a yang data-type the instantiation of which is vendor-specific. 4. Module Structure 4.1. 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: 1. Our current direction is to agree to a routing-instance-centric (VRF) model 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 will augment "/rt:routing/rt:routing-instance/ rt:routing-protocols:" as opposed to augmenting "/rt:routing/ rt:routing-instance/rt:routing-protocols:/rt:routing-protocol" as the latter would allow multiple protocol instances per VRF, which does not make sense for PIM. module: ietf-pim-base augment /rt:routing/rt:routing-protocols: +--rw pim +--rw graceful-restart Liu, et al.

The PIM- DM and BI-DIR modules are just placeholders for now to demonstrate the hierarchy of the model. Other things the draft will include when complete but does not yet include: o Interaction with BFD protocol o Constraints (constant ranges, validation) o State-limiting and policy o Statistics. For these subjects, we will employ the same design principles of expressing a highly general model; vendors may use features and add augmentations in order to express which subsets of this general model are valid in their implementations. 7. Security Considerations The data model defined does not introduce any security implications. This draft does not change any underlying security issues inherent in [I-D.ietf-netmod-routing-cfg]. 8. IANA Considerations TBD 9.
