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].

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,
