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
Liu & Guo Expires April 25, 2015 [Page 2]
Internet-Draft GMP YANG model October 2014
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 gmpInstances : that contains per-instance writable configuration
objects.
The figure below describes the overall structure of the GMP Yang
module :
module: gmp
+--rw gmp
+--rw gmp-Instances
+--rw gmp-Instance * [vrfName]
| ...
+--rw gmp-SSM-Mappings
...
| ...
+--rw gmp-Interfaces
+--rw gmp-Interface * [ifName]
| ...
+--rw gmp-Static-Groups
...
Figure 1 The overview of GMP YANG data model
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
Liu & Guo Expires April 25, 2015 [Page 3]
Internet-Draft GMP YANG model October 2014
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.
+--rw gmp-Instances
+--rw gmp-Instance* [vrfName]
+--rw vrfName string
+--rw addrFamily enumeration
+--rw queryInterval? uint32
+--rw queryRspInterval? uint32

+--rw ipsecName? string
+--rw ipsecType? enumeration
Figure 2 The YANG data model of GMP instance
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].
+--rw gmp-SSM-Mappings
| +--rw gmp-SSM-Mapping
| +--rw IPV4-ssmmapingGrp inet:ipv4-address
| +--rw IPV6-ssmmapingGrp inet:ipv6-address
| +--rw isSSMapMask boolean
| +--rw IPV4-ssmmapingMask? inet:ipv4-address
| +--rw IPV6-ssmmapingMask? uint32
| +--rw isMaskLen boolean
| +--rw maskLen? uint32
| +--rw IPV4-srcAddr inet:ipv4-address
| +--rw IPV6-srcAddr inet:ipv6-address
Figure 3 The YANG data model of GMP SSM-Mapping
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:

Internet-Draft GMP YANG model October 2014
o Per-interface parameters
o Per-static-group configuration of the GMP interface
3.2.3.1. Per-interface Parameters
The per-interface parameter includes the name of the interface, and
the VRF name bound by the interface, and time parameters, policies
etc.
