1. 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].
2. Revision History
A record of changes which will be removed before publication.
20 October 2005
Added explicit reasoning for IPv4-only-osity and for the
unorganized organization.
Updated Copyright and IPR statements.
Updated Security Considerations, per RFC4181.
Added IANA Considerations, per RFC4181.
Added REVISION and WG mailing list to MODULE-IDENTITY, per RFC4181.
Changed some TimeTicks to TimeStamp, on RFC4181's advice.
Fenner Section 2. [Page 2]
INTERNET-DRAFT Expires: April 2006 October 2005
Added advice on non-volatile storage, row creation and column
modification to tables with RowStatus columns, per RFC4181.
Added msdpReadOnlyCompliance to permit implementations that don't
implement writing.
Clarified that msdpSAStatePeriod was an accidental duplication of
msdpCacheLifetime.
Described the epochs for TimeTicks objects, per RFC4181. Add a
note that msdpCacheLifetime would really be better as a
TimeInterval, but is TimeTicks for hysterical raisins.
11 July 2004
Renamed to draft-ietf-mboned-msdp-mib-00.
Fixed spec references and defaults for msdpPeerHoldTimeConfigured,
msdpPeerKeepAliveConfigured and msdpPeerConnectRetryInterval, as
pointed out by Ketan Talaulikar.
Deprecated all objects related to SA-Requests and notifications,
since RFC 3618 doesn't have either one. As pointed out by Ketan
Talaulikar.
Clarified that msdpSACachePeerLearnedFrom should be 0.0.0.0 on the
originator. From Mike Davison.
Removed msdpSAStatePeriod. I couldn't figure out what it's for; at
best it should be SG State Period, but that's already
msdpCacheLifetime. From Mike Davison.
17 October 2003
Undid most of the hard work since draft -03, which is the only
implementation I was able to find by querying the MSDP mailing
list.
29 May 2003
Republished with no changes. How did it get to be almost 2 years?
18 July 2001
Since the INET-ADDRESS-MIB relaxed restrictions on InetAddressType,
remove msdpPeerLocalAddressType, rename msdpSACacheGroupAddrType to
msdpCacheAddrType, remove msdpCacheSourceAddrType,
msdpSACacheOriginRPType, msdpSACachePeerLearnedFromType,
Fenner Section 2. [Page 3]
INTERNET-DRAFT Expires: April 2006 October 2005
msdpSACacheRPFPeerType.
Updated the DESCRIPTION of msdpRequestsTable to describe exactly
how it is used.
Added msdpPeerDiscontinuityTime.
Changed msdpPeerFsmEstablishedTime to a TimeStamp instead of a
counting number of seconds.
Changed msdpPeerInMessageElapsedTime to msdpPeerInMessageTime and
changed it to a TimeStamp.
Added msdpMeshGroupTable.
Updated conformance information.
1 March 2001
Added msdpPeerIfIndex.
Converted all IpAddress items to InetAddressType/InetAddress pairs.
This bigtime violates RFC2578's rules about MIB evolution, so take
extra care when implementing this change.
Added msdpRequestsPriority, in order to allow configuration of
multiple peers to whom Requests will be sent. Note that this
violates RFC2578's rules about MIB evolution, so take extra care
when implementing this change.
Removed DEFVAL on scalars, since it should only be needed for table
row creation.
Removed msdpPeerSAAdvPeriod, since the spec changed to say its
value MUST be 60.
Added none(0) to msdpPeerEncapsulationType enumeration (is this OK?
should it be 4?)
Removed msdpPeerEncapsulationState since the encapsulation
"negotiation" was removed from the spec.
Added msdpRPAddress to specify the RP address to use when sourcing
SA messages.
Added msdpSACacheSourcePrefix to msdpSACacheTable, and added it to
the INDEX. Note that this violates RFC2578's rules about MIB
evolution, so take extra care when implementing this change.
Fenner Section 2. [Page 4]
INTERNET-DRAFT Expires: April 2006 October 2005
Completely renumbered the MIB, removing the extra level of
msdpMIBobjects and creating an msdpScalars group to contain all
scalars. Note that this violates RFC2578's rules about MIB
evolution, so take extra care when implementing this change.
16 December 1999
Added msdpSAHoldDownPeriod, msdpPeerEncapsulationState,
msdpPeerEncapsulationType, msdpPeerConnectionAttempts,
msdpPeerInNotifications, msdpPeerOutNotifications, and
msdpLastError
Removed msdpPeerConfigMethod, since this has disappeared from the
spec.
Renamed the states in msdpPeerState to go with the state machine in
the spec.
Added msdpPeerLocalPort and msdpPeerRemotePort in order to provide
full information about the TCP connection in use. I'd like to
reorder the Peer Table but that can wait until the MIB gets
published as an RFC in order to only change things like that once.
Added msdpSACacheOriginRP as an INDEX to the msdpSACacheTable.
Note that this violates RFC2578's rules about MIB evolution, so
take extra care when implementing this change.
25 June 1999
Renamed to DRAFT-MSDP-MIB. It will be renamed back to MSDP-MIB
when it gets renumbered under mib-2, in order to avoid module
naming problems.
Turned msdpSendRequestsTo into a table in order to handle
administratively scoped groups with different RP's.
27 May 1999
Added IANA-assigned experimental OID
Added msdpSendRequestsTo and msdpPeerProcessRequestsFrom to
configure MSDP SA-Request/Response processing.
Added msdpPeerDataTtl to allow TTL scoping of data packets
forwarded across MSDP peerings.
Renumbered msdpSACacheInDataPackets and further items in
msdpSACacheTable, to eliminate duplicate OIDs

initial version.
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 Cache Table, containing the SA cache entries; and
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 to not create an IPv6
version of the protocol.
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 protcol 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, keeping the experimental OID.

A value of 0 means no SA caching is done by this MSDP
speaker.
Changes to this object should be stored to non-volatile
memory.
This object does not measure time per se; instead, it is the
delta from the time at which an SA message is received at
which it should be expired if not refreshed. (i.e., it is
the value of msdpSACacheExpiryTime immediately after
receiving an SA message applying to that row.) As such,
TimeInterval would be a more appropriate SYNTAX; it remains
TimeTicks for backwards compatability."

empty.
In order to choose a peer to whom to send an SA Request for
a given group G, the subset of entries in this table whose
(msdpRequestsPeerType, msdpRequestsPeer) tuple represents a
peer whose msdpPeerState is established are examined. The
set is further reduced by examining only those entries for
which msdpPeerRequestsGroupAddressType equals the address
type of G, and the entries with the highest value of
msdpRequestsGroupPrefix are considered, where the group G
falls within the range described by the combination of
msdpRequestsGroup and msdpRequestsGroupPrefix. (This
sequence is commonly known as a 'longest-match' lookup.)
Finally, if multiple entries remain, the entry with the
lowest value of msdpRequestsPriority is chosen. The SA
Request message is sent to the peer described by this row."

should be used in providing write access to this object
without adequate authentication.
msdpPeerRemoteAddress is the only variable that must be set
to a valid value before the row can be activated. Since
this is the table's INDEX, a row can be activated by simply
setting the msdpPeerStatus variable.
It is possible to modify other columns in the same

5. Security Considerations
There are a number of management objects defined in this MIB that have a
MAX-ACCESS clause of read-write and/or read-create. Such objects may be
considered sensitive or vulnerable in some network environments. The
support for SET operations in a non-secure environment without proper
protection can have a negative effect on network operations.
There are a number of managed objects in this MIB that may contain
sensitive information. These are:
o The entire msdpPeerTable. Peer information can result in
discovering internal topology, which many want to keep secret.
o msdpNumSACacheEntries. The size of the SA Cache could reveal
whether this system has MSDP entries for public and/or private
groups.
o The entire msdpSACacheTable. The active sources and groups in a
network could be private.
o The entire msdpMeshGroupTable. This information can also lead to
internal topology information.
It is thus important to control even GET access to these objects and
possibly to even encrypt the values of these object when sending them
over the network via SNMP. Not all versions of SNMP provide features
for such a secure environment.
Fenner Section 5. [Page 31]
INTERNET-DRAFT Expires: April 2006 October 2005
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and GET/SET
(read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security features
as provided by the SNMPv3 framework. Specifically, the use of the User-
based Security Model RFC 3414 [2] and the View-based Access Control
Model RFC 3415 [3] is recommended.
It is then a customer/user responsibility to ensure that the SNMP entity
giving access to an instance of this MIB, is properly configured to give
access to the objects only to those principals (users) that have
legitimate rights to indeed GET or SET (change/create/delete) them.
6. IANA Considerations
Since this MIB is for an experimental protocol, it uses an experimental
OID.
