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], STD 58, RFC 2579 [RFC2579] and
        STD 58, 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
   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

   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) as defined in
   [18].

3.1.  Overview

   The MIB provides objects to configure/set-up potential LDP sessions
   on a specific LSR.  A table is used to configure potential LDP
   Sessions, where each row in the table initiates an LDP Session.  This
   is the mplsLdpEntityTable.

   Another table, the mplsLdpEntityPeerTable, mplsLdpPeerTable, is a read-only table which
   records information learned via discovery or from the session
   initialization message.  Each row in the EntityPeer Peer Table represents a peer
   which is known to a specific Entity.  This table carries information
   which is specific to the Entity-Peer interactions but is not
   appropriate for the mplsLdpSessionTable.

   A third table is used to show the actual sessions which have been, or
   are in the process of being established.  Each row represents a
   specific session between an Entity (on this LSR) and a peer.

3.2.  Future Considerations

   The LDP Specification [18] does not specify the use of VPNs or
   multicast for LDP, and thus, objects related to these areas have not
   been included in the MIB.

   This MIB does not include VP merge configuration either.  [32] does
   not yet describe this capability and so it has been excluded from the
   MIB.

   These areas need to be specified in the LDP Specification prior to
   being added in this or any other MIB.

3.3.  Interface Indexing

   Interface Indexes as specified in [29] are used in the MIB.  The
   descriptions of the ifIndexes denote which ifIndex is being used.
   NOTE:  the use of ifIndex is for actual existing connections.

3.3.  Future Considerations

   The following aspects are not addressed in this document:  VPN issues
   (i.e. potential MIB objects such as

3.4.  Differences from the VPN Identifier LDP Specification

   Currently, there are not
   included at 3 differences between this time), specification and lastly, multicast issues are not
   discussed.

   Some of these issues need further clarification before adding to the
   LDP Specification.  As previously mentioned, this MIB is almost
   entirely based on the LDP specification.  The differences are
   documented here in the hope to avoid any confusion between the two
   documents.

   The first difference is that the LDP Entity Table contains some
   DEFVAL clauses which are not specified explicitely in the LDP
   Specification.  These values, although not documented in the LDP
   Specification are widely used by existing LDP MIB implementations and
   thus, have been adopted within this MIB.

3.4.  Please note, they can
   certainly be changed during row creation or a subsequent "set
   request".

   A second difference is the mplsLdpEntityConfGenericLabelRangeTable.
   This table, although added as a way to reserve a range of generic
   labels, does not exist in the LDP Specification.  It was added to the
   MIB in order as there was a request from the working group and is
   considered to be useful for network management.

   The third difference is documented by the TEXTUAL-CONVENTION,
   MplsAtmVcIdentifier. This TC was added to restrict vci values to be
   greater than 31 as described in [32].

3.5.  Discussion of MIB Groups

   Currently, there are four six groups: the MPLS LDP General Group, the MPLS
   LDP ATM Group, the MPLS LDP Frame Relay Group, the MPLS Mapping Group
   and the MPLS LDP Notifications Group.  The MPLS LDP General Group and
   the MPLS LDP Notifications Group should always be supported.  The
   MPLS LDP ATM Group is specific to ATM and should be supported only if
   LDP is using ATM.  Likewise, the MPLS LDP Frame Relay group is
   specific to Frame Relay and should be supported only if LDP is using
   Frame Relay.

3.5.  The MPLS LDP Mapping group should be supported if and
   only if the LSR MIB is supported.

3.6.  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.

3.5.1.

3.6.1.  The Label Distribution Protocol's LDP Entity Table

   The LDP Entity Table provides a way to configure the LSR for using
   LDP.  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.

3.5.2.  Row Creation in the MplsLdpEntity and Associated Tables

3.6.2.  Changing Values After Session Establishment

   It should be noted that special care should be taken if MIB objects
   which are used in the MPLS LDP Session Initialization need to be
   changed AFTER Session Initialization has occurred.  For example,
   currently there is no way to modify a Label Range once a session has
   been established.  Thus, in order to do this, the entire session with
   the peer needs to be torn down.  All related information (LIB and FEC) learned
   during this session needs to be removed from the MIB.  Then and only
   then is it save safe to modify a Label Range.  After modification, the LDP
   Entity will need to go through the Session Initialization again, in
   order to communicate the new Label Ranges to the Peer and establish
   new sessions.

   Please see AdminStatus

3.6.3.  mplsLdpEntityAdminStatus and RowStatus objects in these tables for more
   details.

3.5.3. mplsLdpEntityRowStatus

   The Label Distribution Protocol's Entity ATM Objects

   There exists two tables to configure LDP for using ATM.  These tables
   are mplsLdpEntityAdminStatus object could be viewed as having a
   subset of the mplsLdpEntityAtmParmsTable functionality of the mplsLdpEntityRowStatus object.
   For example, the AdminStatus object has states of enable(1) and
   disable(2).  Setting the
   mplsLdpEntityConfAtmLabelRangeTable.

   The mplsLdpEntityAtmParmsTable provides a way mplsLdpEntityAdminStatus object to configure
   information which would be contained in
   disable(2) and setting the 'Optional Parameter'
   portion of an LDP PDU Initialization Message. mplsLdpEntityRowStatus object to
   notInService(2) are functionally the same.  The motivation behind
   keeping the mplsLdpEntityAdminStatus object is that there could be
   situations where a user would be given write permission to the
   mplsLdpEntityAdminStatus object, but would not be given write
   permission to the mplsLdpEntityRowStatus object.   Having write
   permission to the mplsLdpEntityRowStatus object would mean that a
   user would be able to destroy a row.  This was the motivation for
   keeping the two objects.

3.6.4.  The LDP Entity Generic Objects

   There exists two tables to configure LDP for using Generic Labels.
   These tables are the mplsLdpEntityConfGenericLabelRangeTable and the
   mplsLdpEntityConfGenericTable.  The
   mplsLdpEntityConfGenericLabelRangeTable is for configuring label
   ranges for generic labels.  The mplsLdpEntityConfGenericTable is used
   for configuring generic labels.  In order to reserve a range of
   generic labels, there must be at least one row configured in the
   mplsLdpEntityConfGenericLabelRangeTable.  In order to configure a
   label there must be at least one row in the
   mplsLdpEntityConfGenericLabelRangeTable and one row in
   mplsLdpEntityConfGenericTable.

3.6.5.  The LDP Entity ATM Objects

   There exists two tables to configure LDP for using ATM.  These tables
   are the mplsLdpEntityAtmParmsTable and the
   mplsLdpEntityConfAtmLabelRangeTable.

   The mplsLdpEntityAtmParmsTable provides a way to configure
   information which would be contained in the 'Optional Parameter'
   portion of an LDP PDU Initialization Message.

   The mplsLdpEntityConfAtmLabelRangeTable provides a way to configure
   information which would be contained in the 'ATM Label Range
   Components' portion of an LDP PDU Intialization Message.

3.5.4.

3.6.6.  The Label Distribution Protocol's LDP Entity Frame Relay Objects

   There exists two tables to configure LDP for using Frame Relay.
   These tables are the mplsLdpEntityFrameRelayParmsTable and the
   mplsLdpEntityConfFrLabelRangeTable.

   The mplsLdpEntityFrameRelayParmsTable provides a way to configure
   information which would be contained in the 'Optional Parameter'
   portion of an LDP PDU Initialization Message.

   The mplsLdpEntityConfFrLabelRangeTable provides a way to configure
   information which would be contained in the portion of an LDP PDU
   Intialization Message.

3.5.5.

3.6.7.  The Label Distribution Protocol's LDP 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.

3.5.6.

3.6.8.  The LDP Entity Peer Table

   The LDP Entity Peer Table is a read-only table which contains
   information about LDP Peers known to LDP Entities. A row in this
   table is related to one or more rows in the Hello Adjacency Table and
   one or more rows in the Session Table.  The information in the
   Entity-Peer table is relevant to a Peer but is not the same
   information that is used by the actual session(s) which are related
   to this Peer.  For example, the PathLimit information is gleaned from
   the session initialization phase but is not part of a session if
   there is a mismatch.  In the event of a mismatch, then the session
   will use the PathLimit set by the Entity (and not the Peer).

   A separate table allows for a  more comprehensive and coherent MIB
   model.

3.5.7.

3.6.9.  The LDP Hello 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.

3.5.8.

3.6.10.  The LDP Session Table

   The LDP Session Table is a read-only table.  Each entry in this table
   represents a single session between an LDP Entity and a Peer.

3.5.9.

3.6.11.  The LDP ATM Session Table

   The MPLS LDP ATM Session Table is a read-only table which contains
   session information specific to ATM.

3.5.10.

3.6.12.  The LDP Frame Relay Session Table

   The MPLS LDP Frame Relay Session Table is a read-only table which
   contains session information specific to Frame Relay.

3.5.11.

3.6.13.  The LDP Session Statistics Table

   The MPLS LDP Session Stats Table is a read-only table which contains
   statistical information on sessions.

3.5.12.

3.6.14.  The LDP Session Peer Address Table

   The MPLS LDP Session Peer Address Table is a table which 'extends'
   the mplsLdpSessionTable.  This table is a read-only table which
   stores Addresses learned after session initialization via "Address
   Message" advertisement.

3.5.13.

3.6.15.  The LDP Label Information Base (LIB) Table Mapping Tables

   The MPLS LDP LIB Table is a read-only table which contains
   information stored was removed since it overlapped with the mplsXCTable in
   the LIB.  This table is indexed by a unique
   number which could be used to represent LSR MIB[25].  [ASIDE:  the LSP segment related to
   this mplsXCTable contains all LIB entry. entries,
   not only those for LDP LSP but those for LSPs created by other mpls
   protocols or statically configured. The Lsp number corresponds to removal of the LIB table has
   necessitated a FEC entry way to associate (or map) LDP sessions with certain
   tables in the FEC
   Table which LSR MIB.  For example, if a session is described next.

3.5.14.  The torn down, then
   all related session information must be removed from the both LDP FEC Table MIB
   and the LSR MIB.  The FEC Table is a read-only table mplsInSegmentTable, the mplsOutSegmentTable and
   the mplsXCTable in the LSR MIB could contain rows which contains FEC (Forwarding
   Equivalence Class) information.  Each entry/row represents were created
   as a single
   FEC Element.

3.6.  The LDP Notifications Group

3.6.1. result of an LDP Notifications

   Currently, there Session.  Three mapping tables were added to
   this MIB to map Sessions to the relevant tables in the LSR MIB.
   These mapping tables are two notifications:
   mplsLdpFailedInitSessionThresholdExceeded and
   mplsLdpPathVectorLimitMismatch.

   mplsLdpFailedInitSessionThresholdExceeded is sent when described in the
   'mplsLdpEntityFailedInitSessionThreshold' is exceeded. next few subsections.

3.6.15.1.  The LDP Session In Label Map Table

   This
   notification should indicate table provides a way to the operator that there may be map a
   misconfigured mplsLdpEntityEntry because the session associated with
   this Entity is not being established, and the Entity keeps trying to
   establish the session.  A side effect of this situation mplsInSegmentTable
   in the LSR MIB [25].  When a session is that torn down, this table
   provides a row way to clean up the necessary entries in the mplsLdpSessionTable may not
   mplsInSegmentTable.  If an LSP is terminated on this LSR then there
   will be reaching the operational state
   as indicated by an entry in the

   The mplsLdpPathVectorLimitMismatch notification is sent when table which maps the
   Entity's Path Vector Limit session and the Peer's Path Vector Limit do not
   agree.  In this situation a session could still entry in
   the mplsInSegmentTable.  Please note, there may be established entries which are
   also effected by session teardown in the mplsXCTable. (The
   relationship between the entity mplsInSegmentTable and the peer, using the Entity's Path Vector
   Limit.  For further details, please see Section 3.5.3 of the LDP
   Specification [18].

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-05.txt>

   The majority of changes in this revision are based on Last Call
   comments which were received during the last call from Thursday,
   March 9, 2000 to Friday, March 17, 2000, or slightly thereafter.
   Also, changes were made to agree with the latest specifications.
   These changes are described in this section.

   Changes due to draft-ietf-mpls-ldp-07.txt and draft-ietf-mpls-ldp-
   08.txt. Specifically, removing references to IPv4/IP and using router
   id, as appropriate.

   Removed vpMerge and vpAndVcMerge choices from the object,
   mplsLdpEntityAtmMergeCap.  VP Merge is not described in [32].

   * LIB Table was removed and replaced by 3 different mapping tables to
   map sessions to InSegment, OutSegment and XC tables in the LSR MIB.
   The conformance section was updated to include a Mapping Group which
   is to be implemented iff the LSR MIB is implemented.  * front
   section, need to include something about the
     generic label table JOAN JOAN JOAN update the front section, need
   to add a section on how this differs from the LDP Specification with
   regard to Frame Relay and also the generic label range tables.  *
   more on Row Creation/adminStatus/OperStatus in the LDP Entity
     and related tables.  Need to probably do an algorithm type
     of thing

   Added a generic label range table. NOTE: there is NO corresponding
   LDP message which relates to the information in this table, however,
   this table does provide a way for a user to 'reserve' a generic label
   range.

   A new TEXTUAL-CONVENTION, MplsAtmVcIdentifier was added.  This TC has
   the same upper bounds as AtmVcIdentifier (from rfc2514) except that
   the lower bound is 32 (and not 0).  The lower bound is 32 since this
   value is specified by [32].

   Removed the scalar object mplsLsrLabelRetentionMode and added
   mplsLdpEntityLabelRetentionMode.  The change was made to allow
   configuring the retention mode on a per LDP Entity basis, as opposed
   for the entire LSR.

   Typo in section 3.5.2 was fixed.

   Typo in the mplsLdpSessionUp notification description was fixed.

   Section 'LDP Notifications' was expanded to cover both the
   'mplsLdpSessionUp' and 'mplsLdpSessionDown' traps.  Also, the objects
   which enable and disable these traps have been described in this
   Section:

   The 'mplsLdpEntityHopCountLoopDetection' object and the
   'mplsLdpEntityHopCount' object have been combined into the new
   object, 'mplsLdpEntityHopCountLimit'.

   MplsLabel has been updated to reflect the VPI value of 12 bits and
   not 8.

5.  Revision History

   This section should be removed when this document the 'mplsLdpEntityMaxPduLength'
   object.  The default value is published as an
   RFC.

5.1. 4096 and the units is octets.

   Added DEFVAL clause to 'mplsLdpEntityProtocolVersion' object.  The
   default value is 1.

    Added DEFVAL clause to 'mplsLdpEntityKeepAliveHoldTimer' of 40
   seconds.

   Added DEFVAL clause to 'mplsLdpEntityFailedInitSessionThreshold'
   object.  The default value is 8.

   The mplsLdpEntityWellKnownDiscoveryPort was changed into two objects,
   one for TCP and one for UDP.  The names are

   Typo in the description for the

   The mplsLdpEntityPeerTable was (re-)named mplsLdpPeerTable.  The
   mplsLdpSessionTable now AUGMENTs the mplsLdpPeerTable in order to
   show that these two tables are related.  There has been wording added
   to the mplsLdpSessionEntry description and to the description for the
   mplsLdpPeerTable.

5.2.  Changes from <draft-ietf-mpls-ldp-mib-04.txt>

   Editorial changes, fixing typo's, fixing wrapping lines, etc.

   Updated references for latest drafts, and added [33] and [34] to
   Reference Section.

   Added to the Acknowledgements Section.

   Changed the SYNTAX and DESCRIPTION of the
   'mplsLdpLsrLoopDetectionCapable' object, so that it will also support
   the loop detection by hop count.

   Combined the 'mplsLdpEntityLoopDetectionForPV' and
   'mplsLdpEntityPathVectorLimit' objects.  The functionality of the
   'mplsLdpEntityLoopDectionForPV' is now denoted by the value of 0
   (zero) in the 'mplsLdpEntityPathVectorLimit' object.  This results in
   one less object 'mplsLdpEntityLoopDectionForPV' but does not
   sacrifice functionality.

   Changed 'mplsLdpLibLabelType' into two objects:
   'mplsLdpLibInLabelType' and differ from the egress label type.  The
   MIB now reflects this.

   The following items were changed as a result of the Frame Relay Forum
   dropping support for 17-bit DLCIs:  the MplsLabel TC description has
   been modified, and other Frame Relay Object descriptions were also
   modified (as specified in this section).

   The MplsLabel TC was also modified and reference 3. was added to the
   REFERENCE Clause.

   MplsLdpLabelTypes TC was modified to use an enum.

   InterfaceIndex support was added to the Entity information.  This was
   specifically requested by several members of the working group.  An
   additional table, mplsLdpEntityConfGenericTable as a way to configure
   Generic Labels, and an object, 'mplsLdpConfGenericIfIndexOrZero was
   added to map the InterfaceIndex used by Generic Labels.  Objects were
   also added to the 'mplsLdpEntityAtmParmsTable' and the and
   'mplsLdpEntityFrIfIndex', respectively.

   Changed the name of the 'mplsLdpEntityMtu' object to be
   'mplsLdpEntityMaxPduLength' which is more consistent with the LDP
   Specification.  Also, the description and SYNTAX were changed.

   Changed the SYNTAX of the 'mplsLdpSessionMaxPduLength' to unsigned32
   and changed the Range from (0..65535) to (1..65535).

   Added and improved the front section discussion on SNMP
   Notifications.

   Also, modified the DESCRIPTION clause of the

   Added objects to enable/disable the sending of traps:

   Added an object to enable/disable sending traps for Sessions changing
   from Up to Down, or Down to Up.

   Added notifications to generate traps from session changing from Up
   to Down, or Down to up.

   Added a StorageType object to the Entity and associated tables which
   are configurable.

   Added a Discontinuity Time object to the Entity Table,

   Added discussion on row creation in the Entity and other associated
   Entity tables.  This is a new Section in the Front part of the
   document called:

   Removed the 'mplsLdpEntityControlMethod'.

   Made 'mplsLdpFecLspId' as part of the INDEX for the FEC table.  This
   is to allow FECs to map to multiple LSPs.  Also add a RowPointer to a
   row in the Session Table.

   Added an operation status object, 'mplsLdpLspOperationStatus' 'mplsLdpLspOperStatus' and a last
   Change object, 'mplsLdpLspLastChangeto the LIB Table.  This will be
   used to detect whether an LSP has changed its status.

   Changed the name of the mplsLdpPeerTable to the
   mplsLdpEntityPeerTable.  This table contains information relevant to
   Peers which are known to specific Entities.  The indexing of this
   table has also changed to include the Row in the Entity Table that
   this Peer is known by.  The mplsLdpHelloAdjacencyTable and the
   mplsLdpSessionTable have been moved under this table.  Since Hello
   Adjacencies are related to Entity-Peer information and Sessions are
   related to Entity-Peer information this was seen as a comprehensive
   and coherent modelling.  Associated descriptions in the front section
   and in the tables have been changed to reflect this change.

   Moved the 'mplsLdpConfFrLen' object from the
   'mplsLdpEntityConfFrLabelRangeTable' to the
   'mplsLdpEntityFrameRelayParmsTable' since the Frame Relay
   interface/port can only use one header length at a time, i.e. a
   specific FR interface supports one address length for all VCs on that
   interface. Also, changed the object so that it only supports 10 and
   23 bit DLCI lengths. (The 17 bit length was dropped by the Frame
   Relay Forum and thus, is no longer required.)  The name of this
   object was changed from 'mplsLdpConfFrLen' to 'mplsLdpEntityFrLen' to
   fit in with the 'mplsLdpEntityFrameRelayParmsTable'.

   Removed the seventeenDlciBits(1) value from the mplsLdpFrSessionLen
   object.  (The 17 bit length was dropped by the Frame Relay Forum and
   thus, is no longer required.)

   Corrected the range of the 'mplsLdpEntityIndexNext' object to include
   0 (zero).

5.2.

5.3.  Changes from <draft-ietf-mpls-ldp-mib-03.txt>

   Reworded the description of the mplsLdpAtmSessionTable to clarify
   that one or MORE label range intersection(s) is/are represented in
   this table.

   Reworded the description of the mplsLdpFrameRelaySessionTable to
   clarify that one or MORE label range intersection(s) is/are
   represented in this table.

   Added a new index, mplsLdpSessionPeerIndex, to the
   mplsLdpSessionPeerAddressTable.  This new index uniquely identifies
   the entry within a given session.  (Since  adding
   mplsLdpSessionPeerNextHopAddressType,
   mplsLdpSessionPeerNextHopAddress to the INDEX clause of the
   mplsLdpSessionPeerAddressTable leaves a table with only indices and
   no objects, the work around was to add a new index which uniquely
   differentiates an entry within a given session.)

   Quite a few changes to the mplsLdpPeerTable. First, removed the
   mplsLdpPeerIndex from the mplsLdpPeerTable and other tables.  This
   index served no purpose, so was removed.  Second, removed the
   objects:  mplsLdpPeerInternetworkAddrType, and
   mplsLdpPeerInternetworkAddr. Third, reworded the description of this
   table to include information which is known during Session
   Intialization attempts, the specific information has to do with Loop
   Dection based on Path Vectors.  Since Section 3.5.3 of the LDP Spec
   when describing the PVLim says:  "Although knowledge of a peer's path
   vector limit will not change an LSR's behavior, it does enable the
   LSR to alert an operator to a possible misconfiguration." and the
   object mplsLdpPeerPathVectorLimit is sent as a varbind in the
   mplsLdpPathVectorLimitMismatch notification.

   Removed the mplsLdpPeerIndex from the mplsLdpHelloAdjacencyTable.

   Removed the "IANA Address Family Numbers MIB" section.

   Updated the boiler.me from the ops web page dated Weds., Dec 22,
   1999.

   Updated the Security Section from the ops web page.

   Added the following objects to the mplsLdpEntityTable:
   mplsLdpEntityControlMethod, mplsLdpEntityLoopDectionForPV, and
   mplsLdpEntityPathVectorLimit.

   Removed mplsLdpSessionLabelAdvertisement,
   mplsLdpSessionLoopDetectionForPV, and mplsLdpSessionPathVectorLimit
   from the mplsLdpSessionTable.

   Changed the mplsLdpPathVectorLimitMismatch Notification to send
   mplsLdpEntityPathVectorLimit (instead of
   mplsLdpSessionPathVectorLimit).

   Copied the MplsLabel TC from draft-ietf-mpls-lsr-mib-00.txt and
   replaced the MplsLdpGenAddr for mplsLdpLibInLabel and
   mpslLdpLibOutLabel with MplsLabel.

   The mplsLdpSessionIndex was removed throughout the MIB. This was
   replaced by the object mplsLdpSessionDiscontinuityTime.  The
   motivation was to reduce the number of indices.

   The descriptions for the objects in the mplsLdpSessionStatsTable,
   mplsLdpSessionStatsUnknownMessageTypeErrors and
   mplsLdpSessionStatsUnknownTlvErrors, have been updated to include a
   reference to the mplsLdpSessionDiscontinuityTime object.

5.3.

5.4.  Changes from <draft-ietf-mpls-ldp-mib-02.txt>

   Added Scalar Objects:  mplsLdpLsrLoopDetectionPresent, and
   mplsLdpEntityIndexNext.

   Added the following objects to the mplsLdpEntityTable:
   mplsLdpEntityProtocolVersion, mplsLdpEntityAdminStatus,
   mplsLdpEntityOperStatus, mplsLdpEntityTargetedPeer,
   mplsLdpEntityTargetedPeerAddrType, mplsLdpEntityTargetedPeerAddr, and
   mplsLdpEntityHelloHoldTimer.

   Changed the description of the mplsLdpEntityAtmParmsTable and added
   the following objects to this table:
   mplsLdpEntityAtmLsrConnectivity, mplsLdpEntityDefaultControlVpi,
   mplsLdpEntityDefaultControlVci, mplsLdpEntityUnlabTrafVpi, and
   mplsLdpEntityUnlabTrafVci.  NOTE:  the last four objects were in
   Version 01 of the MIB but were mistakenly omitted from Version 02.
   Now, they are back.

   Changed the indexing of the mplsLdpEntityConfAtmLabelRangeTable to
   include the minimum VPI/VCI.  This is to ensure that indices in this
   table are unique.

   Changed the indexing of the mplsLdpEntityConfFrLabelRangeTable, to
   include the minimum DLCI value.  This is to ensure that indices in
   this table are unique.

   Added [32] to Reference Section.

5.4.

5.5.  Changes from <draft-ietf-mpls-ldp-mib-01.txt>

   The MIB was updated to correspond to draft-ietf-mpls-ldp-06.txt of
   the LDP Specification [18].

   The front section was updated.

   The MIB was made to be less ATM-centric.  Essentially, the ATM
   specific objects where removed from the tables and placed in ATM
   specific Tables.  A "type" was added to the "base" tables and a row
   is to be created in the ATM/FR/etc.  "type" table.  Apropos
   compliance statements were added to reflect the separation of ATM and
   Frame Relay objects into their respective tables.

   Objects for Loop Detection were removed from describing the LDP
   implementation (i.e. the scalars were removed) and Loop Dection
   objects were added to the Session Table.  (Although as the LDP
   Specification indicates loop detection should be for an LSR within a
   domain.)

   The following tables were added:  mplsLdpEntityAtmParmsTable,
   mplsLdpEntityConfAtmLabelRangeTable, mplsLdpFrameRelayParmsTable,
   mplsLdpConfFrLabelRangeTable, mplsLdpAtmSessionTable,
   mpslLdpFrameRelaySessionTable, mplsLdpSessionPeerAddressTable,
   mplsLdpLibTable, and the mplsLdpFecTable.

   The following notifications were added:  notification for Session
   removal.

   The following objects were removed from the Session Table:
   mplsLdpSessionRole was removed (this can be determined by comparing
   LSR Ids and does not need to be explicitely in the MIB.)  ATM
   specific objects (mplsLdpSessionAtmLabelRangeLowerBoundVpi
   mplsLdpSessionAtmLabelRangeLowerBoundVci,
   mplsLdpSessionAtmLabelRangeUpperBoundVpi
   mplsLdpSessionAtmLabelRangeUpperBoundVci) were removed and put into a
   separate table.  Frame Relay objects were added in a separate table.

   Hello Adjacency Table was updated.

   The objects, mplsLdpSessionRejectedParamErrors,
   mplsLdpSessionRejectedNoHelloErrors, mplsLdpBadLdpIdentifierErrors,
   mplsLdpBadPduLengthErrors, mplsLdpBadMessageLengthErrors,
   mplsLdpBadTlvLengthErrors, mplsLdpMalformedTlvValueErrors,
   mplsLdpKeepAliveTimerExpiredErrors, mplsLdpShutdownNotifReceived, and
   mplsLdpShutdownNotifSent were added to the mplsLdpEntityStatsTable.

   The mplsLdpSessionStatsTable was added to count statics based on a
   per Session basis.

   The mplLdpPeerConfAtmLabelRangeTable has been removed.  There is no
   need to configure information for a Peer.  All information for a peer
   is learned, thus peer information is read-only.

   (Editorial) References were updated to reflect the documents which
   this version was based on.

5.5.

5.6.  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, mplsLdpLsrLoopDetectionPresent,
   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.

   References were added and revised.

8.  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 contained in the mplsLdpEntityTable.
   The objects contained in this table are responsible for setting up or
   tearing down LSPs.

   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.

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 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] 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.
