Abstract
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet community. In particular, it describes managed objects
used for managing Multicast Source Discovery Protocol (MSDP) (RFC
3618) speakers.

RFC 4624 MSDP MIB October 2006
1. Introduction
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet community. In particular, it describes managed objects
used for managing Multicast Source Discovery Protocol (MSDP) [1]
speakers.
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 [7].
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 [4], STD 58, RFC 2579 [5] and STD 58, RFC 2580 [6].
3. Overview
This MIB module contains four scalars and four tables, one
deprecated. The tables are:
o The deprecated Requests Table, containing the longest-match table
used to determine the peer to send SA-Requests to for a given
group. This table is deprecated because Requests were removed
from MSDP before it became an RFC.
o The Peer Table, containing information on the system's peers.
o The Source-Active (SA) Cache Table, containing the SA cache
entries.
o The Mesh Group Table, containing the list of MSDP mesh groups to
which this system belongs.
This MIB module uses the IpAddress SYNTAX, making it only suitable
for IPv4 systems. Although the desired direction for MIBs is to use
InetAddressType/InetAddress pairs to allow both IPv4 and IPv6 (and
future formats as well), the MSDP protocol itself is IPv4-only, and
the MSDP working group made an explicit decision not to create an
IPv6 version of the protocol.

RFC 4624 MSDP MIB October 2006
This MIB module is somewhat disorganized, with scalars before and
after tables, holes in the OID space, tables with the RowStatus in
the middle, and so on. This is because objects were added and
removed as necessary as the MSDP protocol evolved, and the plan was
to renumber the whole MIB when moving to the standard mib-2 tree.
The MSDP Working Group then changed direction, publishing the MSDP
protocol as Experimental. Since there were existing implementations
using the strange object order under the experimental OID, the WG
decided not to renumber the MIB and to publish it as experimental,
