                            IP Multicast MIB

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes objects used for managing multicast
   function, independent of the specific multicast protocol(s) in use.
   This document obsoletes RFC 2932.

1.  Introduction

   This MIB describes objects used for managing IP multicast function,
   including IP multicast routing.  These objects are independent of the
   specific multicast routing protocol in use.  Managed objects specific
   to particular multicast protocols are defined elsewhere.

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  History

   This document obsoletes [RFC2932].  The MIB module defined by this
   document is a re-working of the MIB module from [RFC2932], with
   changes that include the following:

   o  This MIB module includes support for IPv6 addressing and the IPv6
      scoped address architecture.  [RFC2932] supported only IPv4.

   o  This MIB module allows several multicast protocols to perform
      routing on a single interface, where [RFC2932] assumed each
      interface supported at most one multicast routing protocol.
      Multicast routing protocols are now per-route, see
      ipMcastRouteProtocol.

   o  This MIB module includes objects that are not specific to
      multicast routing.  It allows management of multicast function on
      systems that do not perform routing, whereas [RFC2932] was
      restricted to multicast routing.

   o  This MIB module includes a table of Source-Specific Multicast
      (SSM) address ranges to which SSM semantics [RFC3569] should be
      applied.

   o  This MIB module includes a table of local applications that are
      receiving multicast data.

   o  This MIB module includes a table of multicast scope zones.

3.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
