1. Introduction
This document defines a YANG [RFC6020] data model for the management
of Internet Group Management Protocol (IGMP) and Multicast Listener
Discovery (MLD) Snooping devices.
This data model includes configuration data and state data (status
information and counters for the collection of statistics).
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119].
The terminology for describing YANG data models is found in[RFC6020].

Internet-Draft IGMP & MLD Snooping Yang Model February 2017
1.2. Tree Diagrams
A simplified graphical representation of the data model is used in
this document. The meaning of the symbols in these diagrams is as
follows:
o Brackets "[" and "]" enclose list keys.
o Abbreviations before data node names: "rw" means configuration
(read-write), and "ro" means state data (read-only).
o Symbols after data node names: "?" means an optional node, "!"
means a presence container, and "*" denotes a list and leaf-list.
o Parentheses enclose choice and case nodes, and case nodes are also
marked with a colon (":").
o Ellipsis ("...") stands for contents of subtrees that are not
shown.
2. Design of Data Model
The model covers Considerations for Internet Group Management
Protocol (IGMP) and Multicast Listener Discovery (MLD) Snooping
Switches [RFC4541].
The goal of this document is to define a data model that provides a
common user interface to IGMP and MLD Snooping. There is very
information that is designated as "mandatory", providing freedom for
vendors to adapt this data model to their respective product
implementations.
2.1. Overview
The IGMP and MLD Snooping YANG module defined in this document has
all the common building blocks for the IGMP and MLD Snooping
protocol. The YANG module includes IGMP and MLD Snooping
configuration data, Operational state data, and the rpc method for
clearing the specified IGMP and MLD Snooping statistics.
2.2. IGMP and MLD Snooping Configuration
The IGMP and MLD Snooping modules define the configuration in a two-
level hierarchy as listed below:

entire routing instance
VLAN-level: IGMP MLD configuration attributes specific to the given
VLAN.

2.3. IGMP and MLD Snooping Operational State
The IGMP and MLD Snooping module contains operational state
information also in a two-level hierarchy as mentioned earlier.

entire routing instance
VLAN-level: IGMP MLD Snooping operational state attributes specific
to the given VLAN.
