1.  Introduction

   [RFC3618] introduces the protocol definition of the Multicast Source
   Discovery Protocol (MSDP).  This document defines a YANG data model
   that can be used to configure and manage MSDP protocol operations.
   The operational state data and statistics can also be retrieved by
   this model.

   This model is designed to be used along with other multicast YANG
   data models such as PIM [PIM-YANG], which are not covered in this
   document.

1.1.  Terminology

   The terminology for describing YANG data models is found in [RFC6020]
   and [RFC7950], including:

   *  action

   *  augment

   *  choice

   *  container

   *  data model

   *  data node

   *  grouping

   *  identity

   *  leaf

   *  list

   *  module

   *  uses

   The following abbreviations are used in this document and the defined
   model:

   MSDP: Multicast Source Discovery Protocol [RFC3618]

   RP: Rendezvous Point [RFC7761]

   RPF: Reverse Path Forwarding [RFC7761]

   SA: Source-Active [RFC3618]

1.2.  Conventions Used in This Document

   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] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

1.3.  Tree Diagrams

   Tree diagrams used in this document follow the notation defined in
   [RFC8340].

1.4.  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.
