Standards Track [Page 3] + +RFC 7453 MPLS-TP MIB February 2015 + + +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 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 in Section 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 to section 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. Overview + +3.1. 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. Standards Track [Page 5] + +RFC 7453 MPLS-TP MIB February 2015 + + +3.2. 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 Profile + +4. 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 2015 + + +5. 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 in Section 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 in Section 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 2015 + + +6.2. 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, in + + + + +Venkatesan, 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 2015 + + +6.5. 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 in Section 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.

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.

Security Considerations + + This document follows the security considerations mentioned in + Section 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 to + + + +Venkatesan, et al. Standards Track [Page 57] + +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.
