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 managed objects for the Multiprotocol
Label Switching, Label Distribution Protocol (LDP) [18].
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 [22].
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
1215 [RFC1215]. The second version, called SMIv2, is described
in STD 58, RFC 2578 [RFC2578], RFC 2579 [RFC2579] and RFC 2580
[RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [RFC1901]
and RFC 1906 [RFC1906]. The third version of the message
protocol is called SNMPv3 and described in RFC 1906 [RFC1906],
RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [RFC1157]. A second set of
protocol operations and associated PDU formats is described in
RFC 1905 [RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described
in RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
Expires December 1999 [Page 3]
INTERNET-DRAFT MPLS LDP MIB June 1999
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.

3. Structure of the MIB
The following aspects are not addressed in this document: Interfaces
with respect to the IFMIB (e.g. is ldp an interface in the sense of
being stacked onto of the data link layer, and its relationship to
the network layer), VPN issues (i.e. potential MIB objects such as
the VPN Identifier are not included at this time), and lastly,
multicast issues are not discussed.
Some of these issues need further clarification before adding to this
MIB.
Currently, there is two groups. The MPLS LDP General Group and the
MPLS LDP Notifications Group.
3.1. The MPLS LDP General Group
This group contains information about the specific LDP Entities which
are associated with this agent. Each LSR must have one LDP Entity.
3.1.1. The Label Distribution Protocol's Entity Table
The LDP Entity Table represents the LDP Entities which exist on a
single Label Switch Router (LSR). The LDP Entity performs the LDP
protocol. There must be at least one LDP Entity for the LSR to
support LDP.
Each entry/row in this table represents a single LDP Entity.
3.1.2. The Label Distribution Protocol's Entity Statistics Table
The LDP Entity Statistics Table will maintain counters related to an
LDP Entity. This Table should be a read-only table which contains
statistical information.
Each row in this table will be related to a single LDP Entity.
3.1.3. The LDP Peer Table
The LDP Peer Table contains information about LDP Peers. Each row in
this table represents an LDP Peer which is known to an LDP Entity.
Expires December 1999 [Page 5]
INTERNET-DRAFT MPLS LDP MIB June 1999
3.1.4. The LDP Sessions Table
Each entry in this table represents a session between an LDP Entity
and a Peer.
3.1.5. The LDP Adjacencies Table
This is a table of all adjacencies between all LPD Entities and all
LDP Peers. A Session may have one or more adjacencies.
3.1.6. The LDP Label Information Base (LIB) Table
TBD. Some potential objects: incoming label, outgoing label, and the
mid.
3.2. The LDP Notifications Group
3.2.1. LDP Notifications
Currently, there is one notification which will be sent when an LDP
attempts to initialize the same session beyond the configured
threshold.

Expires December 1999 [Page 15]
INTERNET-DRAFT MPLS LDP MIB June 1999
NOTE: The ranges for a specific LDP Entity
are UNIQUE and non-overlapping. For example,
for a specific LDP Entity index, there could
be one entry having ConfLowerBound vpi/vci == 0/32, and
ConfUpperBound vpi/vci == 0/100, and a second entry for this
same interface with ConfLowerBound vpi/vci == 0/101 and
ConfUpperBound vpi/vci == 0/200. However, there could not be
a third entry with ConfLowerBound vpi/vci == 0/200 and
ConfUpperBound vpi/vci == 0/300 because this label range overlaps
with the second entry (i.e. both entries now have 0/200).
A row will not be created unless a unique and non-overlapping
range is specified. Thus, row creation implies a one-shot
row creation of LDP EntityID and ConfLowerBound vpi/vci and
ConfUpperBound vpi/vci. At least one label range entry
for a specific LDP Entity MUST include the default VPI/VCI
values denoted in the LDP Entity Table."

DESCRIPTION
"A row in the LDP Peer Configurable ATM Label Range Table.
Expires December 1999 [Page 20]
INTERNET-DRAFT MPLS LDP MIB June 1999
One entry in this table contains information
on a single range of labels represented by
the configured Upper and Lower Bounds VPI/VCI pairs.
NOTE: The ranges for a specific LDP Peer
are UNIQUE and non-overlapping. For example,
for a specific LDP Peer index, there could
be one entry having ConfLowerBound vpi/vci == 0/32, and
ConfUpperBound vpi/vci == 0/100, and a second entry for this
same interface with ConfLowerBound vpi/vci == 0/101 and
ConfUpperBound vpi/vci == 0/200. However, there could not be
a third entry with ConfLowerBound vpi/vci == 0/200 and
ConfUpperBound vpi/vci == 0/300 because this label range overlaps
with the second entry (i.e. both entries now have 0/200).
A row will not be created unless a unique and non-overlapping
range is specified. Thus, row creation implies a one-shot
row creation of LDP PeerIndex and ConfLowerBound vpi/vci and
ConfUpperBound vpi/vci. At least one label range entry
for a specific LDP Peer MUST include the default VPI/VCI
values denoted in the LDP Peer Table."

5. Revision History
This section should be removed when this document is published as an
RFC.
5.1. Changes from <draft-ietf-mpls-ldp-mib-00.txt>
Textual conventions were added for the LSR Identifier and the LDP
Identifier.
Top-level mib structure was added. The LDP MIB falls under a proposed
hierarchy of mpls.mplsProtocols.
The mib hierarchy within the LDP MIB was also changed. A new branch,
under mpls.mplsProtocols.mplsLdpMIB.mplsLdpObjects was added. This
branch is mplsLdpLsrObjects. Currently, this contains several new
scalar objects: mplsLdpLsrID, mplsLdpLsrLoopDectectionPresent,
mplsLdpLsrLoopDetectinAdminStatus, mplsLdpLsrPathVectorLimit,
mplsLdpLsrHopCountLimit, mplsLdpLsrLoopPreventionPresent,
mplsLdpLsrLoopPreventionAdminStatus, and
mplsLdpLsrLabelRetentionMode.
mplsLdpEntityTable is now indexed by mplsLdpEntityIdentifier, which
is the LDP Identifier used in Session establishment.
mplsLdpEntityLoopDetection and mplsLdpEntityLoopPrevention objects
were removed from this table.
The following objects were added to the mplsLdpEntityTable:
mplsLdpEntityLabelSpaceType, mplsLdpEntityUnlabTrafVpi,
mplsLdpEntityUnlabTrafVci, mplsLdpEntityMergeCapability,
mplsLdpEntityVcDirectionality, and
mplsLdpEntityLabelDistributionMethod.
The following objects were added to the mplsLdpPeerEntityTable:
mplsLdpPeerLabelDistributionMethod.
The following object was removed from the mplsLdpEntityStatsTable:
mplsLdpEntityEstablishedSessions.
The LIB table was added.
The following notifications were added.
References were added and revised.
6. TO DO List
