1.  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 PIM.  It includes PIM SM[RFC4601], PIM
   SSM[RFC4607][RFC4608],PIM BSR[RFC5059].  In addition, It can extend

   PIM DM[RFC3973], BIDIR PIM[RFC5015] etc. features described in PIM
   standards other than mentioned above RFC in future version.

2.  Terminology

   o  PIM: Protocol Independent Multicast

   o  SM: Sparse Mode

   o  SSM: Source-specific Multicast

   o  DM: Dense Mode

   o  BSR: Bootstrap Router

   o  RP: Rendezvous Point

   o  SPT: shortest-path tree

   o  RPT: Rendezvous Point Tree

   o  RPF: Reverse Path Forwarding

3.  Design of Data Model

3.1.  Overview

   Because PIM SSM is a subset of PIM SM, it is not necessary to assign
   a separate container for PIM SSM.  The PIM Yang module is divided
   into two main containers :

   o  pim-bsr : that contains all pim bsr&rp writable configuration
      objects and operation states.

   o  pim-sm : that contains all pim sm writable configuration objects
      and operation states.

   The figure below describes the overall structure of the PIM Yang
   module :

3.2.  PIM BSR Configuration

   PIM BSR configuration container has only one main container:

   o  pim-bsr-instances : that contains all pim c-bsr and c-rp writable
      configuration objects.

   PIM BSR per-instance configuration container includes c-bsr and c-rp
   parameters of the public PIM instance or the PIM instance binding a
   specific VRF.  PIM BSR per-instance configuration container is
   divided into:

   o  Per-instance c-bsr configuration of the pim-bsr instance.

   o  Per-instance c-rp configuration of the pim-bsr instance.

3.2.1.  Per-instance C-BSR Configuration of PIM BSR Instance

   The per-instance C-BSR configuration includes the name of the VRF
   bound by the pim bsr instance, and timer parameters , policies etc.
   it also includes administratively scoped BSR configuration.

3.3.  PIM BSR Operation State

   PIM BSR container provides operational states for BSR and RP
   information.  This container is divided in three components:

   o  pim-bsr-ebsr-infos : provide elected bsr state information.

   o  pim-bsr-cbsr-infos : provide candidate bsr state information.

   parameters of the public PIM instance or the PIM instance binding a
   specific VRF.  PIM SM per-instance configuration container is divided
   into:

   o  Per-instance parameters

   o  Per-static-rp configuration of the pim-sm instance

   o  Per-spt-switch configuration of the pim-sm instance

   o  Per-anycast-rp configuration of the pim-sm instance

   o  Per-interface configuration of the pim-sm instance

3.4.1.  Per-instance Parameters

   The per-instance parameter includes the name of the VRF bound by the
   PIM SM instance, and timer parameters such as hello interval etc.,
   and varied policies etc

3.4.2.  Per-static-RP configuration of the PIM SM instance

   Per-static-RP configuration of the PIM SM instance includes static RP
   address, preference and policy for group range.  For simply
   deployment, sometimes it is not necessary to deploy dynamic BSR/RP
   mechanism, and static RP mechanism is also satisfied.

   Per-SPT-switch configuration of the PIM SM instance includes spt
   switch threshold, group range by policy.PIM SM SPT switch process as

3.4.4.  Per-Anycast-RP configuration of the PIM SM instance

   Anycast-RP as described in [RFC4610] is a mechanism that pim sm
   register packets have been used to exchange multicast source
   information and get fast convergence when a PIM Rendezvous Point (RP)
   router fails.  Per-Anycast-RP configuration container is divided into
   :

   o  Per-anycast-rp parameters

   o  Per-rp-peer configuration of PIM SM Anycast RP

3.4.4.1.  Per-Anycast-RP Parameters

   Per-Anycast-RP parameter includes the RP for anycast address, and the
   local address to establish RP peer link.

   neighbor,routing etc. information.  This container is divided in
   multiple components:

      information for all of the PIM SM interfaces.

   o  pim-nbr-infos : provide neighbor state information for all of the
      PIM SM neighbors.
