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 IGMP and MLD.  It includes IGMPv1[RFC1112],
   IGMPv2[RFC2236], IGMPv3[RFC3376] and MLDv1[RFC2710], MLDv2[RFC3810].
   In addition, features described in IGMP and MLD standards other than
   mentioned above RFC are also supported.  For convenience, IGMP and
   MLD are wholly called GMP below.

2.  Terminology

   o  IGMP: Internet Group Management Protocol

   o  MLD: Multicast Listener Discovery

   o  GMP: Group Management Protocol

   o  SSM: Source-Specific Multicast

3.  Design of Data Model

3.1.  Overview

   The GMP Yang module has only one main container ::

   o  gmp-instances : that contains per-instance writable configuration
      objects.

   o  gmp-group-infos : provide IGMP or MLD group state for all of the
      dynamic group members.

   o  gmp-static-group-infos : provide IGMP or MLD static group state
      for all of the static group members.

   o  gmp-if-infos : provide IGMP or MLD interface state and running
      parameters for all of the IGMP or MLD interfaces.

   o  gmp-packet-statistics : provide IGMP or MLD packet statistical
      information for all of the IGMP or MLD protocol packets.

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

3.2.  GMP Per-instance Configuration

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

   o  Per-instance parameters

   o  Per-SSM-Mapping configuration of the GMP instance

   o  Per-interface configuration of the GMP instance

3.2.1.  Per-instance Parameters

   The per-instance parameter includes the name of the VRF bound by the
   GMP instance, and timer parameters such as query interval etc.

3.2.2.  Per-SSM-Mapping Configuration of GMP Instance

   Per-SSM-Mapping configuration of the GMP instance includes the SSM
   Mapping rules.IGMPv1/v2 and MLDv1 reports can use these rules to map
   SG state for PIM SSM[RFC4607].IGMPv3 and MLDv2 can default use PIM
   SSM , which is described in [RFC4604].

3.2.3.  Per-interface Configuration of GMP Instance

   Per-interface configuration of the GMP instance includes the
   interface name, timer parameters, policies, static groups etc.GMP
   per-instance configuration container is divided into two containers:

   o  Per-interface parameters

   o  Per-static-group configuration of the GMP interface

3.3.  Operational State

   "gmp" container provides operational states for IGMP or MLD.  This
   container is divided in four components:

   o  gmp-group-infos : provide IGMP or MLD group state for all of the
      dynamic group members.

   o  gmp-static-group-infos : provide IGMP or MLD static group state
      for all of the static group members.

   o  gmp-if-infos : provide IGMP or MLD interface state and running
      parameters for all of the IGMP or MLD interfaces.

   o  gmp-packet-statistics : provide IGMP or MLD packet statistical
      information for all of the IGMP or MLD protocol packets.
