1. Introduction
YANG [RFC7950] is a data modeling language that was introduced to
model the configuration and operational state of a device managed
using network management protocols such as NETCONF [RFC6241] or
RESTCONF [RFC8040]. YANG is now also being used as a component of
other management interfaces, such as CLIs.
This document defines a YANG data model that can be used to configure
and manage devices supporting Protocol Independent Multicast (PIM).
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. Terminology
The terminology for describing YANG data models is found in
[RFC7950].

1.3. 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.

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 devices
supporting PIM with various specifications, including some with basic
subsets of the PIM protocol. The main design goals of this document
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.
Liu, et al. Expires November 20, 2018 [Page 6]
Internet-Draft PIM YANG May 2018
For the same reason, wide constant ranges (for example, timer maxima
and minima) are 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) [RFC8342]. The operational state data is combined with the
associated configuration data in the same hierarchy
[I-D.ietf-netmod-rfc6087bis].
2.4. Module and Hierarchy Organization
This model defines several separate modules for modelling PIM
configuration, defined below. Again, this separation makes it easier
to express the specific capabilities of a PIM device. The module
organization, along with the usage of the YANG extensible features
such as identity, allows the model to be easily augmented for new
capabilities.
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 are 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.
2.5. 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.
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

Internet-Draft PIM YANG May 2018
parameter above the address-family level, or by a constraint on the
base model objects of a form similar to:
deviation "/rt:routing/rt:control-plane-protocols/"
+ "pim-base:pim/pim-base:interfaces/pim-base:interface/"
+ "pim-base:address-family" {
deviate add {
must "(address-family = 'rt:ipv4' and dr-priority = "
+ "../address-family[address-family = 'rt:ipv6']/"
+ "dr-priority) or "
+ "(address-family = 'rt:ipv6' and dr-priority = "
+ "../address-family[address-family = 'rt:ipv4']/"
+ "dr-priority)" {
error-message
"Error: IPv6 DR priority must match IPv4 DR priority.";
error-app-tag "dr-priority-mismatch";
}
}
}
3. Module Structure
3.1. PIM Base Module
The PIM base module defines the base framework not specific to any
PIM mode, and is imported by the other modules. The base module by
itself does not provide sufficient data for any PIM mode to operate.
Other mode specific and feature specific modules need to be
implemented in addition to this module, depending on the feature set
required by the implementation.
This model augments the core routing data model "ietf-routing"
specified in [RFC8349]. 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, while the PIM protocol is
designed to be enabled or disabled as a single protocol instance on a
network instance or a logical network element.
3.1.1. High-Level Structure
The high-level structure of the model is shown below:
Liu, et al. Expires November 20, 2018 [Page 8]
Internet-Draft PIM YANG May 2018
module: ietf-pim-base
augment /rt:routing/rt:control-plane-protocols:
+--rw pim!
+--rw <global configuration>
+--ro <global operational state>
+--rw address-family* [address-family]
| +--rw address-family identityref
| +--rw <per address family configuration>
| +--ro <per address family operational state>
+--rw interfaces
+--rw interface* [name]
+--rw name if:interface-ref
+--rw address-family* [address-family]
+--rw address-family identityref
+--rw <per interface configuration>
+--ro <per interface operational state>
+--ro neighbors
+--ro ipv4-neighbor* [address]
| +--ro address inet:ipv4-address
| +--ro <IPv4 per neighbor operational state>
+--ro ipv6-neighbor* [address]
+--ro address inet:ipv6-address
+--ro <IPv4 per neighbor operational state>
The presence of the top-level container "pim" enables the PIM
protocols.
3.1.2. Global Data
The global configuration and operational state data covers the
support for graceful restart in the PIM base model. Additional
features can be added by augmentation if required by an
implementation.
3.1.3. Per Address Family Data
The support for per address family data is shown below:
Liu, et al. Expires November 20, 2018 [Page 9]

| | +--ro expiration? rt-types:timer-value-seconds16
| | +--ro up-time? rt-types:timeticks64
| | +--ro jp-state? enumeration
This is the location that most of the PIM RP module (ietf-pim-rp)
augments. Each of the mode specific modules also augments this
schema tree.

+--rw pim!
+--rw interfaces
+--rw interface* [name]
+--rw name if:interface-ref
+--rw address-family* [address-family]

The support for bfd is achieved by using a grouping provided by an
external module ietf-bfd-types, defined in [I-D.ietf-bfd-yang].
3.1.5. Neighbor Modeling
For each PIM interface, there can be a list of neighbors, which
contain operational state data. To model such data, the following
structure is specified:
+--rw pim!
+--rw interfaces
+--rw interface* [name]
+--rw address-family* [address-family]
+--ro neighbors
+--ro ipv4-neighbor* [address]
| +--ro address inet:ipv4-address
| +--ro bfd-status? enumeration
| +--ro expiration?
| | rt-types:timer-value-seconds16
| +--ro dr-priority? uint32
| +--ro gen-id? uint32
| +--ro lan-prune-delay
| | +--ro present? boolean
| | +--ro override-interval? uint16
| | +--ro propagation-delay? uint16
| | +--ro t-bit? boolean
| +--ro up-time? rt-types:timeticks64
+--ro ipv6-neighbor* [address]
+--ro address inet:ipv6-address
+--ro bfd-status? enumeration
+--ro expiration?

| +--ro present? boolean
| +--ro override-interval? uint16
| +--ro propagation-delay? uint16
| +--ro t-bit? boolean
+--ro up-time? rt-types:timeticks64
3.1.6. Notifications
The PIM base module also defines the notifications for PIM interface
and neighbor events, as shown below:
Liu, et al. Expires November 20, 2018 [Page 12]
Internet-Draft PIM YANG May 2018
notifications:
+---n pim-neighbor-event
| +--ro event-type? neighbor-event-type
| +--ro interface-ref? leafref
| +--ro interface-af-ref? leafref
| +--ro neighbor-ipv4-ref? leafref
| +--ro neighbor-ipv6-ref? leafref
| +--ro up-time? rt-types:timeticks64
+---n pim-interface-event
+--ro event-type? interface-event-type
+--ro interface-ref? leafref
+--ro ipv4
| +--ro address* inet:ipv4-address
| +--ro dr-address? inet:ipv4-address
+--ro ipv6
+--ro address* inet:ipv6-address
+--ro dr-address? inet:ipv6-address
3.2. PIM RP Module
The PIM RP module augments the PIM base module to define the
configuration and operational state information scoped to RP related
features:
module: ietf-pim-rp
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:address-family:
+--rw rp
+--rw static-rp
...
+--rw bsr {bsr}?
...
+--ro rp-list
...
+--ro rp-mappings
...
This module is shared by the PIM-SM mode and the PIM-BIDIR mode, but
not by the PIM-DM mode. PIM-SM module and PIM-BIDIR module augment
this module to cover mode specific data.
The following sections describe the features and capabilities covered
in this module.

Internet-Draft PIM YANG May 2018
3.2.1. Static RP
Static RPs can be configured by using the following portion of the
module:
+--rw rp
+--rw static-rp
| +--rw ipv4-rp* [rp-address]
| | +--rw rp-address inet:ipv4-address
| +--rw ipv6-rp* [rp-address]
| +--rw rp-address inet:ipv6-address
3.2.2. BSR
The support for BSR includes both configuration data and operational
state data, as shown below:

3.2.3. RP State Data
This portion of the model provides the operational state information
for all RPs on the router, including the statically configured RPs
and the BSR elected RPs.

| +--ro expiration? rt-types:timer-value-seconds16
3.2.4. RP to Group Mappings
The operational state data of the mappings between RPs and multicast
groups is modeled as follows:
+--rw rp
+--ro rp-mappings
+--ro ipv4-rp* [group rp-address]
| +--ro group inet:ipv4-prefix
| +--ro rp-address inet:ipv4-address
| +--ro up-time? rt-types:timeticks64

+--ro rp-address inet:ipv6-address
+--ro up-time? rt-types:timeticks64
+--ro expiration? rt-types:timer-value-seconds16
3.2.5. Notifications
The PIM RP module also defines the notifications for RP related
events, as shown below:
Liu, et al. Expires November 20, 2018 [Page 16]
Internet-Draft PIM YANG May 2018
notifications:
+---n pim-rp-event
+--ro event-type? rp-event-type
+--ro instance-af-ref? leafref
+--ro group? rt-types:ip-multicast-group-address
+--ro rp-address? inet:ip-address
+--ro is-rpt? boolean
+--ro mode? pim-base:pim-mode
+--ro message-origin? inet:ip-address
3.3. PIM-SM Module
The PIM-SM module covers Sparse Mode modeling, including PIM-ASM and
PIM-SSM. This module has dependencies on PIM base module and PIM RP
module, both of which are augmented by this module.
The augmentation to the address-family branch of the PIM base module
is shown below:
module: ietf-pim-sm
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:address-family:
+--rw sm
+--rw asm
| +--rw anycast-rp!
| | +--rw ipv4-anycast-rp* [anycast-address rp-address]
| | | +--rw anycast-address inet:ipv4-address
| | | +--rw rp-address inet:ipv4-address
| | +--rw ipv6-anycast-rp* [anycast-address rp-address]
| | +--rw anycast-address inet:ipv6-address
| | +--rw rp-address inet:ipv6-address
| +--rw spt-switch
| +--rw infinity! {spt-switch-infinity}?
| +--rw policy-name? string {spt-switch-policy}?
+--rw ssm!
+--rw range-policy? string
To support SM mode on an interface, this module augments the
interface branch of the PIM base module, as follows:
Liu, et al. Expires November 20, 2018 [Page 17]
Internet-Draft PIM YANG May 2018
module: ietf-pim-sm
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:interfaces/pim-base:interface/pim-base:address-family:
+--rw sm!
+--rw passive? empty
This module also augments the PIM RP module to allow an RP to be
configured in the PIM-SM mode:
module: ietf-pim-sm
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:address-family/pim-rp:rp/pim-rp:static-rp/pim-rp:ipv4-rp:
+--rw sm!
+--rw policy-name? string
+--rw override? boolean {static-rp-override}?
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:address-family/pim-rp:rp/pim-rp:static-rp/pim-rp:ipv6-rp:
+--rw sm!
+--rw policy-name? string
+--rw override? boolean {static-rp-override}?
3.4. PIM-DM Module
The PIM-DM module covers Dense Mode modeling. This module augments
the PIM base module, but it has no dependency on the PIM RP module.
module: ietf-pim-dm
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:address-family:
+--rw dm!
augment /rt:routing/rt:control-plane-protocols/pim-base:pim
/pim-base:interfaces/pim-base:interface
/pim-base:address-family:
+--rw dm!
3.5. PIM-BIDIR Module
The PIM-BIDIR module covers Bidirectional PIM modeling. Like PIM-SM,
this module augments both PIM base module and PIM RP module.
The followings are the augmentations to the PIM base module, on the
address-family, the interface, and the neighbor branches:

This module also augments the PIM RP module to extend the
capabilities of RP for the PIM-BIDIR mode:

7. 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
Liu, et al. Expires November 20, 2018 [Page 89]
Internet-Draft PIM YANG May 2018
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
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
8. Security Considerations
The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC5246].
The NETCONF access control model [RFC6536] provides the means to
restrict access for particular NETCONF or RESTCONF users to a
preconfigured subset of all available NETCONF or RESTCONF protocol
operations and content.
There are a number of data nodes defined in this YANG module that are
writable/creatable/deletable (i.e., config true, which is the
default). These data nodes may be considered sensitive or vulnerable
in some network environments. Write operations (e.g., edit-config)
to these data nodes without proper protection can have a negative
effect on network operations. These are the subtrees and data nodes
and their sensitivity/vulnerability:
Liu, et al. Expires November 20, 2018 [Page 90]
Internet-Draft PIM YANG May 2018
pim-base:graceful-restart
This subtree specifies the configuration for the PIM graceful
restart at the global level on a device. Modifying the
configuration can cause temporary interruption to the multicast
routing during restart.
pim-base:address-family/pim-base:graceful-restart
This subtree specifies the per address family configuration for
the PIM graceful restart on a device. Modifying the configuration
can cause temporary interruption to the multicast routing during
restart.
pim-base:address-family/pim-rp:pim-rp:rp
This subtree specifies the configuration for the PIM Rendezvous
Point (RP) on a device. Modifying the configuration can cause RP
malfunctions.
pim-base:address-family/pim-sm:sm
This subtree specifies the configuration for the PIM Sparse Mode
(PIM-SM) on a device. Modifying the configuration can cause
multicast traffic disabled or rerouted in PIM-SM.
pim-base:address-family/pim-dm:dm
This subtree specifies the configuration for the PIM Dense Mode
(PIM-DM) on a device. Modifying the configuration can cause
multicast traffic disabled or rerouted in PIM-DM.
pim-base:address-family/pim-bidir:bidir
This subtree specifies the configuration for the PIM Bidirectional
Mode (PIM-BIDIR) on a device. Modifying the configuration can
cause multicast traffic disabled or rerouted in PIM-BIDIR.
pim-base:interfaces
This subtree specifies the configuration for the PIM interfaces on
a device. Modifying the configuration can cause the PIM protocol
to get insufficient or incorrect information.
These subtrees are all nnder /rt:routing/rt:control-plane-protocols/
pim-base:pim.
Unauthorized access to any data node of these subtrees can adversely
affect the multicast 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.
Some of the readable data nodes in this YANG module may be considered
sensitive or vulnerable in some network environments. It is thus
important to control read access (e.g., via get, get-config, or
Liu, et al. Expires November 20, 2018 [Page 91]
Internet-Draft PIM YANG May 2018
notification) to these data nodes. These are the subtrees and data
nodes and their sensitivity/vulnerability:
/rt:routing/rt:control-plane-protocols/pim-base:pim
Unauthorized access to any data node of the above subtree can
disclose the operational state information of PIM on this device.
