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 the Internet
   Group Management Protocol (IGMP) and the Multicast Listener Discovery
   (MLD) protocol.

1.  Introduction

   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 the Internet
   Group Management Protocol (IGMP) version 1 [RFC1112], version 2
   [RFC2236], or version 3 [RFC3376] and the Multicast Listener
   Discovery (MLD) protocol version 1 [RFC2710] or version 2 [RFC3810].
   Both protocols provide multicast membership discovery capability.
   IGMP pertains to IP version 4 clients, and MLD to IP version 6
   clients.  This version of the MIB obsoletes both RFC 2933 [RFC2933]
   and RFC 3019 [RFC3019], incorporating a generic interface for both
   IGMP and MLD implementations and incorporating changes to enable
   "source filtering" in multicast clients.  The MIB encompasses both
   router and host nodes with relevant management objects defined for
   each.

2.  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
   RFC 3410 [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
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

   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 RFC 2119 [RFC2119].

4.  Overview

   This Multicast Group Membership Discovery (MGMD) MIB module contains
   eight tables:

   1.  the MGMD Host Interface Table, which contains one row for each
       interface on which IGMP or MLD is enabled on a host,

   2.  the MGMD Router Interface Table, which contains one row for each
       interface on which MGMD is enabled on a router,
