RFC 7453                       MPLS-TP MIB                 February 20151.  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 additional textual conventions and   managed objects for tunnels, identifiers, and Label Switching Routers   to support Multiprotocol Label Switching (MPLS) MIB modules for   transport networks.  MIB modules defined in this document extend the   existing MPLS MIB objects in such a way that they support the MPLS   Transport Profile (MPLS-TP) but also other MPLS networks.  Hence,   "MPLS-TP" is not included in the MIB module names.   As described in the MPLS Traffic Engineering (TE) MIB definition   [RFC3812], MPLS traffic engineering is concerned with the creation   and management of MPLS tunnels.  This term is a shorthand for a   combination of one or more LSPs linking an ingress and an egress LSR.   Several types of point-to-point MPLS tunnels may be constructed   between a pair of LSRs A and B:      - Unidirectional with a single LSP (say, from A to B).      - Associated bidirectional consisting of two separately routed        LSPs, one linking A to B and the other linking B to A.        Together, the pair provides a single logical bidirectional        transport path.      - Co-routed bidirectional consisting of an associated        bidirectional tunnel but with the second LSP from B to A        following the reverse of the path of the LSP from A to B, in        terms of both nodes and links.   Tunnels may be either statically configured by management action or   dynamically created using an LSP management protocol.   The existing MPLS TE MIB [RFC3812] and the GMPLS TE MIB [RFC4802]   address only a subset of the combinations of statically and   dynamically configured tunnel types, catering to statically   configured unidirectional tunnels together with dynamically   configured unidirectional and co-routed bidirectional tunnels.  They   are also restricted to two endpoint LSRs identified by IP addresses.   The MPLS-TP TE MIB defined in this document extends the MIB modules   defined in [RFC3812] to cover all six combinations (that is, adding   support for statically configured associated and co-routed   bidirectional plus dynamically configured associated bidirectional   tunnels).  It also extends support to endpoints that have identifiers   other than IP addresses.Venkatesan, et al.           Standards Track                    [Page 4]

RFC 7453                       MPLS-TP MIB                 February 2015   This support is provided by a suite of four MIB modules that are to   be used in conjunction with the MIB modules defined in [RFC3812] and   the companion document [RFC3813] for MPLS-TP tunnel management.   At the time of writing, SNMP SET is no longer recommended as a way to   configure MPLS networks as described in [RFC3812].  However, since   the MIB modules specified in this document extend and are intended to   work in parallel with the MIB modules for MPLS specified in   [RFC3812], certain objects defined here are specified with MAX-ACCESS   of read-write or read-create so that specifications of the base   tables in [RFC3812] and the extensions in this document are   consistent.  Although the examples described inSection 9 specify   means to configure MPLS-TP Tunnels in a similar way to the examples   in [RFC3812], this should be seen as indicating how the MIB values   would be returned if the specified circumstances were configured by   alternative means.2.  The Internet-Standard Management Framework   For a detailed overview of the documents that describe the current   Internet-Standard Management Framework, please refer tosection 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].3.  Overview3.1.  Conventions Used in This Document   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and   "OPTIONAL" in this document are to be interpreted as described in   [RFC2119].Venkatesan, et al.

RFC 7453                       MPLS-TP MIB                 February 20153.2.  Terminology   This document uses terminology from the "Multiprotocol Label   Switching Architecture" [RFC3031], "Multiprotocol Label Switching   (MPLS) Traffic Engineering (TE) Management Information Base (MIB)"   [RFC3812], "Multiprotocol Label Switching (MPLS) Label Switching   Router (LSR) Management Information Base (MIB)" [RFC3813], and"MPLS   Transport Profile (MPLS-TP) Identifiers" [RFC6370].3.3.  Acronyms   CC: Country Code   ICC: ITU Carrier Code   LSP: Label Switched Path   LSR: Label Switching Router   MPLS-TP: MPLS Transport Profile   TE: Traffic Engineering   TP: Transport Profile4.  Motivations   "Multiprotocol Label Switching (MPLS) Traffic Engineering (TE)   Management Information Base (MIB)" [RFC3812] provides support for   Traffic Engineering tunnels.  In MPLS, the actual transport of   packets is provided by Label Switched Paths (LSPs).  A transport   service may be composed of multiple LSPs.  In order to clearly   identify the MPLS-TP service, as defined in [RFC6370], we use the   term "MPLS-TP Tunnel" or simply "tunnel".  However, with MPLS-TP, the   characteristics of the tunnels were enhanced.  For example, MPLS-TP   Tunnels are bidirectional in nature and could be used with non-IP   identifiers for the tunnel endpoints.  As the existing   MPLS-TE-STD-MIB and GMPLS-TE-STD-MIB were defined mainly to support   unidirectional tunnels and signaled co-routed bidirectional tunnel   definitions, respectively, these existing MIB modules are not   sufficient to capture all the characteristics of the tunnels.  Hence,   enhancing the MIB modules to support MPLS-TP Tunnels is required.  As   most of the attributes of MPLS Traffic Engineering tunnels are also   applicable to MPLS-TP Tunnels, it is optimal to reuse and extend the   existing MIB module definition instead of defining a new MIB module.   This document defines four additional MIB modules, namely,   MPLS-TE-EXT-STD-MIB, MPLS-TC-EXT-STD-MIB, MPLS-ID-STD-MIB, and   MPLS-LSR-EXT-STD-MIB.  As these additional MIB modules are required   for MPLS-TP functionality, these are all defined in this document,   instead of being documented separately.Venkatesan, et al.           Standards Track                    [Page 6]

RFC 7453                       MPLS-TP MIB                 February 20155.  Feature List   The MIBs in this document satisfy the following requirements and   constraints:   The MIB modules, taken together, support statically configured and   dynamically signaled point-to-point, co-routed bidirectional and   associated bidirectional tunnels.      - The MPLS tunnels need not be interfaces, but it is possible to        configure an MPLS-TP Tunnel as an interface.  The same ifType        150, as defined inSection 8 of [RFC3812], will be used for        MPLS-TP Tunnels as well.      - The mplsTunnelTable [RFC3812] is also to be used for MPLS-TP        Tunnels.      - New MPLS-TP-specific textual conventions and identifiers are        required.      - The mplsTunnelTable is sparsely extended to support objects        specific to MPLS-TP Tunnels.      - A node configuration table (mplsTunnelExtNodeConfigTable), as        detailed inSection 6.2.1, below, is used to translate the        Global_ID::Node_ID or ICC_Operator_ID::Node_ID to the local        identifier in order to index the mplsTunnelTable.      - The mplsXCTable is sparsely extended to support objects specific        to MPLS-TP XC (Cross Connect).      - The MIB module supports persistent, as well as non-persistent,        tunnels.6.  Outline   Traffic Engineering support for the MPLS-TP Tunnels requires the   setup of the co-routed or associated bidirectional tunnel.  The   tables and MIB modules that are mentioned in the below subsections   support the functionality described in [RFC5654] and [RFC6370].   These tables support both IP-compatible and ICC-based tunnel   configurations.   Figure 1, below, depicts how the table references are followed in   this MIB.Venkatesan, et al.

MIB Module Extensions   Four MIB modules are extended to support MPLS-TP Tunnels, namely,   MPLS-TE-EXT-STD-MIB, MPLS-TC-EXT-STD-MIB, MPLS-ID-STD-MIB, and   MPLS-LSR-EXT-STD-MIB.  The following section provides the summary of   changes.6.1.1.  Summary of MIB Module Changes   - Node configuration table (mplsTunnelExtNodeConfigTable) for setting     the local identifier for Tunnel Ingress and Egress identifiers.   - Node IP map table (mplsTunnelExtNodeIpMapTable) for querying the     local identifier for a given Global_ID and Node_ID.   - Node ICC map table (mplsTunnelExtNodeIccMapTable) for querying the     local identifier for a given ICC_Operator_ID and Node_ID.   - Tunnel extension table (mplsTunnelExtTable) for setting up MPLS-TP     Tunnels with sparse extension of mplsTunnelTable.   - Textual conventions and object definitions for MPLS-TP Tunnels.   - Cross-connect extension table (mplsXCExtTable) for setting up the     MPLS-TP LSPs.     These tables are described in the subsequent sections.Venkatesan, et al.           Standards Track                    [Page 8]

RFC 7453                       MPLS-TP MIB                 February 20156.2.  MPLS-TE-EXT-STD-MIB     The TE MIB module extensions and details of the tables are     described in the following sections.6.2.1.  mplsTunnelExtNodeConfigTable   The mplsTunnelExtNodeConfigTable is used to assign a local identifier   for a given ICC_Operator_ID::Node_ID or Global_ID::Node_ID   combination as defined in [RFC6923] and [RFC6370], respectively.  The   CC is a string of two characters, each being an uppercase Basic Latin   alphabetic (i.e., A-Z).  The ICC is a string of one to six   characters, each an uppercase Basic Latin alphabetic (i.e., A-Z) or   numeric (i.e., 0-9).  All of the characters are encoded using [T.50]   as described in [RFC6370].   In the IP-compatible mode, Global_ID::Node_ID, is used to uniquely   identify a node.  For each ICC_Operator_ID::Node_ID or   Global_ID::Node_ID, there is a unique entry in the table representing   a node.  As the regular TE tunnels use the IP address as the LSR ID,   the local identifier should be below the first valid IP address,   which is 16777216[1.0.0.0].  Every node is assigned a local   identifier within a range of 0 to 16777215.  This local identifier is   used for indexing into mplsTunnelTable as mplsTunnelIngressLSRId and   mplsTunnelEgressLSRId.   For IP-compatible environments, an MPLS-TP Tunnel is indexed by   Tunnel Index, Tunnel Instance, Source Global_ID, Source Node_ID,   Destination Global_ID, and Destination Node_ID.   For ICC-based environments, an MPLS-TP Tunnel is indexed by Tunnel   Index, Tunnel Instance, Source CC, Source ICC, Source Node_ID,   Destination CC, Destination ICC, and Destination Node_ID.   As mplsTunnelTable is indexed by mplsTunnelIndex, mplsTunnelInstance,   mplsTunnelIngressLSRId, and mplsTunnelEgressLSRId, the MPLS-TP tunnel   identifiers cannot be used directly.   The mplsTunnelExtNodeConfigTable will be used to store an entry for   ICC_Operator_ID::Node_ID or Global_ID::Node_ID with a local   identifier to be used as the LSR ID in mplsTunnelTable.6.2.2.  mplsTunnelExtNodeIpMapTable   The read-only mplsTunnelExtNodeIpMapTable is used to query the local   identifier assigned and stored in mplsTunnelExtNodeConfigTable for a   given Global_ID::Node_ID.  In order to query the local identifier, inVenkatesan, et al.           Standards Track                    [Page 9]

RFC 7453                       MPLS-TP MIB                 February 2015   the IP-compatible mode, this table is indexed with   Global_ID::Node_ID.  In the IP-compatible mode for a TP tunnel,   Global_ID::Node_ID is used.   A separate query is made to get the local identifier of both Ingress   and Egress Global_ID::Node_ID identifiers.  These local identifiers   are used as mplsTunnelIngressLSRId and mplsTunnelEgressLSRId when   indexing mplsTunnelTable.6.2.3.  mplsTunnelExtNodeIccMapTable   The read-only mplsTunnelExtNodeIccMapTable is used to query the local   identifier assigned and stored in the mplsTunnelExtNodeConfigTable   for a given ICC_Operator_ID::Node_ID.   A separate query is made to get the local identifier of both Ingress   and Egress ICC_Operator_ID::Node_ID.  These local identifiers are   used as mplsTunnelIngressLSRId and mplsTunnelEgressLSRId when   indexing mplsTunnelTable.6.2.4.  mplsTunnelExtTable   This table sparsely extends the mplsTunnelTable in order to support   MPLS-TP Tunnels with additional objects.  All the additional   attributes specific to supporting a TP tunnel are contained in this   extended table and could be accessed with the mplsTunnelTable   indices.   The gmplsTunnelReversePerfTable [RFC4802] should be used to provide   per-tunnel packet performance information for the reverse direction   of a bidirectional tunnel.  It can be seen as supplementing the   mplsTunnelPerfTable, which augments the mplsTunnelTable.6.3.  MPLS-TC-EXT-STD-MIB   This MIB module contains textual conventions for LSPs of MPLS-based   transport networks.6.4.  MPLS-ID-STD-MIB   This MIB module contains identifier object definitions for MPLS   Traffic Engineering in transport networks.Venkatesan, et al.           Standards Track                   [Page 10]

RFC 7453                       MPLS-TP MIB                 February 20156.5.  MPLS-LSR-EXT-STD-MIB   This MIB module contains generic object definitions (including the   mplsXCExtTable -- cross-connect extension table -- for setting up the   MPLS-TP LSPs with sparse extension of mplsXCTable) for MPLS LSRs in   transport networks.6.6.  The Use of RowPointer   This document follows the RowPointer usage as described inSection 10   of [RFC3812].   A new RowPointer object, mplsTunnelExtOppositeDirPtr, is added to   mplsTunnelExtTable of MPLS-TE-EXT-STD-MIB module.  This RowPointer   object points to the tunnel entry in the opposite direction.   Two additional RowPointers objects, mplsXCExtTunnelPointer and   mplsXCExtOppositeDirXCPtr, are added to the mplsXCExtTable of   MPLS-LSR-EXT-STD-MIB.  The RowPointer mplsXCExtTunnelPointer is a   read-only object used to indicate the back pointer to the tunnel   entry.  The RowPointer mplsXCExtOppositeDirXCPtr object points to the   opposite-direction XC entry.   If either of these RowPointers return zeroDotZero, it implies that   there is no entry associated with the RowPointer object.7.  MIB Modules' Interdependencies   This section provides an overview of the relationships between the   MPLS-TP TE MIB module and other MPLS MIB modules.   The arrows in the following diagram show a "depends on" relationship.   A relationship of "MIB module A depends on MIB module B" means that   MIB module A uses an object, object identifier, or textual convention   defined in MIB module B, or that MIB module A contains a pointer   (index or RowPointer) to an object in MIB module B.Venkatesan, et al.

The new mplsTunnelExtTable provides the reverse-direction LSP   information for the existing tunnel table so that bidirectional LSPs   can be created.   The mplsXCExtTable sparsely extends the mplsLsrXCTable to provide   backward reference to tunnel entry.9.  Example of MPLS-TP Tunnel Setup   In this section, we provide an example of configuring MPLS-TP   bidirectional tunnels with IP tunnel identifiers.  This example   provides the usage of the MPLS-TP Tunnel MIB along with the extended   MIB modules introduced in this document.Venkatesan, et al.           Standards Track                   [Page 13]

RFC 7453                       MPLS-TP MIB                 February 2015   Do note that a MPLS-TP Tunnel could be set up statically as well as   signaled via the control plane.  This example considers accessing MIB   objects on a head-end for static and signaled MPLS-TP Tunnels.  This   section shows the configuration of the forward- and reverse-direction   MPLS-TP LSPs that run between East and West, and vice versa.  Only   objects relevant to MPLS-TP Tunnels are illustrated here.   In mplsTunnelExtNodeConfigTable:   {   -- Non-IP Ingress LSR_ID (Index to the table)     mplsTunnelExtNodeConfigLocalId              = 1,     mplsTunnelExtNodeConfigGlobalId             = 1234,     mplsTunnelExtNodeConfigNodeId               = 10,   -- Mandatory parameters needed to activate the row go here     mplsTunnelExtNodeConfigRowStatus         = createAndGo (4)   -- Non-IP Egress LSR ID (Index to the table)     mplsTunnelExtNodeConfigLocalId              = 2,     mplsTunnelExtNodeConfigGlobalId             = 1234,     mplsTunnelExtNodeConfigNodeId               = 20,   -- Mandatory parameters needed to activate the row go here     mplsTunnelExtNodeConfigRowStatus         = createAndGo (4)   }   This will create an entry in the mplsTunnelExtNodeConfigTable for a   Global_ID::Node_ID.  The Ingress and Egress LSR are represented by   separate entries.   The following read-only mplsTunnelExtNodeIpMapTable table is   populated automatically upon creating an entry in   mplsTunnelExtNodeConfigTable, and this table is used to retrieve the   local identifier for the given Global_ID::Node_ID.   In mplsTunnelExtNodeIpMapTable:   {   -- Global_ID (Index to the table)     mplsTunnelExtNodeIpMapGlobalId             = 1234,   -- Node Identifier (Index to the table)     mplsTunnelExtNodeIpMapNodeId               = 10,     mplsTunnelExtNodeIpMapLocalId              = 1   -- Global_ID (Index to the table)     mplsTunnelExtNodeIpMapGlobalId             = 1234,Venkatesan, et al.

If the configured range is not an          IP address, the operator is expected to retrieve the          complete information (Global_ID::Node_ID or          ICC_Operator_ID::Node_ID) from mplsTunnelExtNodeConfigTable.          This way, the existing mplsTunnelTable is reused for          bidirectional tunnel extensions for MPLS-based transport          networks.          The local identifier allows the operator to assign          a unique identifier to map Global_ID::Node_ID and/or          ICC_Operator_ID::Node_ID.  As this local identifier is unique          within the node and the same syntax of this object can be          used for MPLS-TE tunnel also, it is up to the operator/local          management entity to choose a non-conflicting value for          indexing the MPLS and MPLS-TP tunnel entries."       ::= { mplsTunnelExtNodeConfigEntry 1 }    mplsTunnelExtNodeConfigGlobalId  OBJECT-TYPE       SYNTAX        MplsGlobalId       MAX-ACCESS    read-create       STATUS        current       DESCRIPTION         "This object indicates the Global Operator Identifier.

Security Considerations   This document follows the security considerations mentioned inSection 12 of [RFC3812].  These security considerations are also   applicable to the MIB objects and tables defined in this document,   which are identified as below.      - The common objects mplsIdGlobalId, mplsIdNodeId, mplsIdCc, and        mplsIdIcc are used to define the identity of an MPLS-TP node for        OAM purposes.  If write-access is allowed to these objects it        offers the possibility for incorrect values to be entered that        will confuse the information returned by OAM functions and        possibly prevent OAM from operating correctly.  Furthermore,        there is the possibility of inducing one node to impersonate        another with confusing results.      - mplsTunnelExtNodeConfigTable, mplsTunnelExtTable and        mplsXCExtTable collectively contain objects to provision MPLS-TP        Tunnels, tunnel hops, and tunnel resources.   Some of the readable objects in this MIB module (i.e., objects with a   MAX-ACCESS other than not-accessible) may be considered sensitive or   vulnerable in some network environments.  It is thus important to   control even GET and/or NOTIFY access to these objects and possibly   to even encrypt the values of these objects when sending them over   the network via SNMP.  These are the tables and objects and their   sensitivity/vulnerability:      - mplsTunnelExtNodeConfigTable, mplsTunnelExtTable, and        mplsXCExtTable collectively show the characteristics of the        MPLS-TP tunnel network topology.  If an Administrator does not        want to reveal this information, then these tables should be        considered sensitive/vulnerable.   SNMP versions prior to SNMPv3 did not include adequate security.   Even if the network itself is secure (for example by using IPsec),   there is no control as to who on the secure network is allowed toVenkatesan, et al.

RFC 7453                       MPLS-TP MIB                 February 2015   access and GET/SET (read/change/create/delete) the objects in this   MIB module.   Implementations SHOULD provide the security features described by the   SNMPv3 framework (see [RFC3410]), and implementations claiming   compliance to the SNMPv3 standard MUST include full support for   authentication and privacy via the User-based Security Model (USM)   [RFC3414] with the AES cipher algorithm [RFC3826].  Implementations   MAY also provide support for the Transport Security Model (TSM)   [RFC5591] in combination with a secure transport such as SSH   [RFC5592] or TLS/DTLS [RFC6353].   Further, deployment of SNMP versions prior to SNMPv3 is NOT   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to   enable cryptographic security.  It is then a customer/operator   responsibility to ensure that the SNMP entity giving access to an   instance of this MIB module 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.15.  IANA Considerations   As described in [RFC4221] and [RFC6639], and as requested in the   MPLS-TC-STD-MIB [RFC3811], MPLS-related Standards Track MIB modules   should be rooted under the mplsStdMIB subtree.  There are four MPLS   MIB modules contained in this document; each of the following   subsections lists a new assignment made by IANA under the mplsStdMIB   subtree.  New assignments can only be made via a Standards Action as   specified in [RFC5226].15.1.  IANA Considerations for MPLS-TC-EXT-STD-MIB   IANA has assigned the OID { mplsStdMIB 17 } to the   MPLS-TC-EXT-STD-MIB module specified in this document.15.2.
