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 modeling a + Multiprotocol Label Switching (MPLS) [RFC3031] based traffic + engineering. This MIB module should be used in conjunction with the + companion document [RFC3813] for MPLS based traffic engineering + configuration and management. + + 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 BCP 14, RFC 2119, + reference [RFC2119]. + +2. Terminology + + This document uses terminology from the MPLS architecture document + [RFC3031] and MPLS Label Switch Router MIB [RFC3813]. Some + frequently used terms are described next. + + An explicitly routed LSP (ERLSP) is referred to as an MPLS tunnel. + It consists of in-segment(s) and/or out-segment(s) at the + egress/ingress LSRs, each segment being associated with one MPLS + interface. These are also referred to as tunnel segments. + Additionally, at an intermediate LSR, we model a connection as + consisting of one or more in-segments and/or one or more out- + segments. The binding or interconnection between in-segments and + out-segments is performed using a cross-connect. These objects are + defined in the MPLS Label Switch Router MIB [RFC3813]. + + + + + + +Srinivasan, et al. Standards Track [Page 2] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + +3. 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]. + +4. Feature List + + The MPLS traffic engineering MIB module is designed to satisfy the + following requirements and constraints: + + - The MIB module supports configuration of point-to-point + unidirectional tunnels. + + - MPLS tunnels need not be interfaces, but it is possible to + configure a tunnel as an interface. + + - The MIB module supports tunnel establishment via an MPLS + signalling protocol wherein the tunnel parameters are specified + using this MIB module at the head end of the LSP, and end-to-end + tunnel LSP establishment is accomplished via signalling. The MIB + module also supports manually configured tunnels, i.e., those for + which label associations at each hop of the tunnel LSP are + provisioned by the administrator via the LSR MIB [RFC3813]. + + - The MIB module supports persistent, as well as non-persistent + tunnels. + +5. Outline + + Traffic engineering support for MPLS tunnels requires the following + configuration: + + - Setting up MPLS tunnels along with appropriate configuration + parameters. + + - Configuring tunnel for loose and strict source routed hops. + + + + + +Srinivasan, et al. Standards Track [Page 3] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + These actions may need to be accompanied by corresponding actions + using [RFC3813] to establish and configure tunnel segments, if this + is done manually. Also, the in-segment and out-segment performance + tables, mplsInSegmentPerfTable, and mplsOutSegmentPerfTable + [RFC3813], should be used to determine performance of the tunnels and + tunnel segments, in addition to mplsTunnelPerfTable in this MIB + module. + +5.1. Summary of Traffic Engineering MIB Module + + The MIB module objects for performing these actions consist of the + following tables: + + - Tunnel table (mplsTunnelTable) for setting up MPLS tunnels. + + - Resource table (mplsTunnelResourceTable) for setting up the tunnel + resources. + + - Tunnel specified, actual, and computed hop tables + (mplsTunnelHopTable, mplsTunnelARHopTable, and + mplsTunnelCHopTable) for strict and loose source routed MPLS + tunnel hops. + + - Tunnel performance table (mplsTunnelPerfTable) for measuring + tunnel performance. + + - CRLDP resource table (mplsTunnelCRLDPResTable) for specifying + resource objects applicable to tunnels signaled using CRLDP. + + These tables are described in the subsequent sections. + +6. Brief Description of MIB Objects + + The objects described in this section support the functionality + described in documents [RFC3209] and [RFC3212]. The tables support + both manually configured and signaled tunnels. + +6.1. mplsTunnelTable + + The mplsTunnelTable allows new MPLS tunnels to be created between an + MPLS LSR and a remote endpoint, and existing tunnels to be + reconfigured or removed. Note that we only support point-to-point + tunnels, although multipoint-to-point and point-to-multipoint + connections are supported by an LSR acting as a cross-connect. Each + MPLS tunnel can thus have one out-segment originating at an LSR + and/or one in-segment terminating at that LSR. + + + + + +Srinivasan, et al. Standards Track [Page 4] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + mplsTunnelTable does not define the in and out segments forming the + tunnel. Instead, these are defined by creating rows in the in- + segment and out-segment tables, defining relationships in the cross- + connect table, and referring to these rows in the mplsTunnelTable + using a cross-connect index, mplsTunnelXCIndex. These segment and + cross-connect related objects are defined in [RFC3813]. + +6.2. mplsTunnelResourceTable + + mplsTunnelResourceTable is used to indicate the resources required + for a tunnel. Multiple tunnels may share the same resources by + pointing to the same entry in this table. Tunnels that do not share + resources must point to separate entries in this table. + +6.3. mplsTunnelHopTable + + mplsTunnelHopTable is used to indicate the hops, strict or loose, for + an MPLS tunnel defined in mplsTunnelTable, when it is established via + signalling. Multiple tunnels may share the same hops by pointing to + the same entry in this table. Each row also has a secondary index, + mplsTunnelHopIndex, corresponding to the next hop of this tunnel. + The scalar mplsTunnelMaxHops indicates the maximum number of hops + that can be specified on each tunnel supported by this LSR. + + At transit LSRs, this table contains the hops, strict or loose, that + apply to the downstream part of this tunnel only. This corresponds + to the requested path received through the signaling protocol. + +6.4. mplsTunnelARHopTable + + mplsTunnelARHopTable is used to indicate the actual hops traversed by + a tunnel as reported by the MPLS signalling protocol after the tunnel + is setup. The support of this table is optional since not all MPLS + signalling protocols may support this feature. + + At transit LSRs, this table contains the actual hops traversed by the + tunnel along its entire length if that information is available. + This corresponds to the recorded path reported by the MPLS signalling + protocol, possibly derived from multiple signaling messages. + +6.5. mplsTunnelCHoptable + + mplsTunnelCHopTable lists the actual hops computed by a constraint- + based routing algorithm based on the mplsTunnelHopTable for the MPLS + signalling protocol in use. The support of this table is optional + since not all implementations may support computation of hop lists + using a constraint-based routing protocol. + + + + +Srinivasan, et al. Standards Track [Page 5] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + At transit LSRs, this table contains the hops computed to apply to + the downstream part of this tunnel. This corresponds to the + requested path signaled from this LSR through the signaling protocol. + +6.6. mplsTunnelPerfTable + + mplsTunnelPerfTable provides several counters to measure the + performance of the MPLS tunnels. This table augments + mplsTunnelTable. + +6.7. mplsTunnelCRLDPResTable + + mplsTunnelCRLDPResTable contains resource information for those + tunnels that are signaled using CRLDP [RFC3212]. This is a sparse + extension to mplsTunnelResourceTable and is also indexed by + mplsTunnelResourceIndex. As with mplsTunnelResourceTable, multiple + tunnels may share the same resources by pointing to the same entry in + this table. Tunnels that do not share resources must point to + separate entries in this table. The mplsTunnelCRLDPResTable may be + supported only by implementations that support the CR-LDP signaling + protocol. + +7. Use of 32-bit and 64-bit Counters + + 64-bit counters are provided in this MIB module for high-speed + interfaces where the use of 32-bit counters might be impractical. + The requirements on the use of 32-bit and 64-bit counters (copied + verbatim from [RFC2863]) are as follows: + + For interfaces that operate at 20,000,000 (20 million) bits per + second or less, 32-bit byte and packet counters MUST be supported. + For interfaces that operate faster than 20,000,000 bits/second, and + slower than 650,000,000 bits/second, 32-bit packet counters MUST be + supported and 64-bit octet counters MUST be supported. For + interfaces that operate at 650,000,000 bits/second or faster, 64-bit + packet counters AND 64-bit octet counters MUST be supported. + +8. Application of the Interface Group to MPLS Tunnels + + The Interfaces Group of MIB II defines generic managed objects for + managing interfaces. This memo contains the media-specific + extensions to the Interfaces Group for managing MPLS Tunnels as + logical interfaces. + + This memo assumes the interpretation of the Interfaces Group to be in + accordance with [RFC2863] which states that the interfaces table + (ifTable) contains information on the managed resource's interfaces + and that each sub-layer below the internetwork layer of a network + + + +Srinivasan, et al. Standards Track [Page 6] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + interface is considered an interface. Thus, the MPLS interface is + represented as an entry in the ifTable. The inter-relation of + entries in the ifTable is defined by the Interfaces Stack Group + defined in [RFC2863]. + + When using MPLS Tunnels as interfaces, the interface stack table + might appear as follows: + + +------------------------------------------------+ + | MPLS tunnel interface ifType = mplsTunnel(150) | + +------------------------------------------------+ + | MPLS interface ifType = mpls(166) | + +------------------------------------------------+ + | Underlying layer | + +------------------------------------------------+ + + In the above diagram, "Underlying Layer" refers to the ifIndex of any + interface type for which MPLS internetworking has been defined. + Examples include ATM, Frame Relay, and Ethernet. + +8.1. Support of the MPLS Tunnel Interface by ifTable + + Some specific interpretations of the ifTable for those MPLS tunnels + represented as interfaces follow: + + Object Use for the MPLS tunnel. + + ifIndex Each MPLS tunnel is represented by an + ifEntry. + + ifDescr Description of the MPLS tunnel. + + ifType The value that is allocated for the MPLS + tunnel is 150. + + ifSpeed The total bandwidth in bits per second + for use by the MPLS tunnel. + + ifPhysAddress Unused. + + ifAdminStatus See [RFC2863]. + + ifOperStatus This value reflects the actual + operational status of the MPLS tunnel. + Assumes the value down(2) if the MPLS + tunnel is down. + + ifLastChange See [RFC2863]. + + + +Srinivasan, et al. Standards Track [Page 7] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + ifInOctets The number of octets received over the + MPLS tunnel. + + ifOutOctets The number of octets transmitted over + the MPLS tunnel. + + ifInErrors The number of labeled packets dropped + due to uncorrectable errors. + + ifInUnknownProtos The number of received packets + discarded during packet header + validation, including packets with + unrecognized label values. + + ifOutErrors See [RFC2863]. + + ifName Textual name (unique on this system) of + the MPLS tunnel or an octet string of + zero length. + + ifLinkUpDownTrapEnable + Default is disabled (2). + + ifConnectorPresent Set to false (2). + + ifHighSpeed See [RFC2863]. + + ifHCInOctets The 64-bit version of ifInOctets; + supported if required by the compliance + statements in [RFC2863]. + + ifHCOutOctets The 64-bit version of ifOutOctets; + supported if required by the compliance + statements in [RFC2863]. + + ifAlias The non-volatile 'alias' name for the + MPLS tunnel as specified by a network + manager. + +9. Example of Tunnel Setup + + This section contains an example of which MIB objects should be + modified if one would like to create a best effort, loosely routed, + unidirectional traffic engineered tunnel, which spans two hops of a + simple network. Note that these objects should be created on the + "head-end" LSR. Those objects relevant to illustrating the + relationships amongst different tables are shown here. Other objects + may be needed before conceptual row activation can happen. + + + +Srinivasan, et al. Standards Track [Page 8] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + The RowStatus values shown in this section are those to be used in + the set request, typically createAndGo(4) which is used to create the + conceptual row and have its status immediately set to active. A + subsequent retrieval operation on the conceptual row will return a + different value, such as active(1). Please see [RFC2579] for a + detailed discussion on the use of RowStatus. + + In mplsTunnelResourceTable: + + { + mplsTunnelResourceIndex = 5, + mplsTunnelResourceMaxRate = 0, + mplsTunnelResourceMeanRate = 0, + mplsTunnelResourceMaxBurstSize = 0, + mplsTunnelResourceMeanBurstSize = 0, + mplsTunnelResourceExBurstSize = 0, + mplsTunnelResourceExBurstSize = unspecified (1), + mplsTunnelResourceWeight = 0, + -- Mandatory parameters needed to activate the row go here + mplsTunnelResourceRowStatus = createAndGo (4) + } + + The next two instances of mplsTunnelHopEntry are used to denote the + hops this tunnel will take across the network. + + The following denotes the beginning of the tunnel, or the first hop. + We have used the fictitious LSR identified by "192.168.100.1" as our + example head-end router. + + In mplsTunnelHopTable: + + { + mplsTunnelHopListIndex = 1, + mplsTunnelPathOptionIndex = 1, + mplsTunnelHopIndex = 1, + mplsTunnelHopAddrType = ipv4 (1), + mplsTunnelHopIpAddr = "192.168.100.1", + mplsTunnelHopIpPrefixLen = 32, + mplsTunnelHopType = strict (2), + mplsTunnelHopInclude = true (1), + mplsTunnelHopPathOptionName = "Here to there", + mplsTunnelHopEntryPathComp = explicit (2), + -- Mandatory parameters needed to activate the row go here + mplsTunnelHopRowStatus = createAndGo (4) + } + + + + + + +Srinivasan, et al. Standards Track [Page 9] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + The following denotes the end of the tunnel, or the last hop in our + example. We have used the fictitious LSR identified by + "192.168.101.1" as our end router. + + In mplsTunnelHopTable: + + { + mplsTunnelHopListIndex = 1, + mplsTunnelPathOptionIndex = 1, + mplsTunnelHopIndex = 2, + mplsTunnelHopAddrType = ipv4 (1), + mplsTunnelHopIpAddr = "192.168.101.1", + mplsTunnelHopIpPrefixLen = 32, + mplsTunnelHopType = loose (2), + mplsTunnelHopInclude = true (1), + mplsTunnelHopPathOptionName = "Here to there", + mplsTunnelHopEntryPathComp = explicit (2), + -- Mandatory parameters needed to activate the row go here + mplsTunnelHopRowStatus = createAndGo (4) + } + + The following denotes the configured tunnel "head" entry: + + In mplsTunnelTable: + + { + mplsTunnelIndex = 1, + mplsTunnelInstance = 0, + mplsTunnelIngressLSRId = 192.168.100.1, + mplsTunnelEgressLSRId = 192.168.101.1, + mplsTunnelName = "My first tunnel", + mplsTunnelDescr = "Here to there", + mplsTunnelIsIf = true (1), + -- RowPointer MUST point to the first accessible column + mplsTunnelXCPointer = 0.0, + mplsTunnelSignallingProto = none (1), + mplsTunnelSetupPrio = 0, + mplsTunnelHoldingPrio = 0, + mplsTunnelSessionAttributes = 0, + mplsTunnelLocalProtectInUse = false (0), + -- RowPointer MUST point to the first accessible column + mplsTunnelResourcePointer = mplsTunnelResourceMaxRate.5, + mplsTunnelInstancePriority = 1, + mplsTunnelHopTableIndex = 1, + mplsTunnelIncludeAnyAffinity = 0, + mplsTunnelIncludeAllAffinity = 0, + mplsTunnelExcludeAnyAffinity = 0, + mplsTunnelPathInUse = 1, + + + +Srinivasan, et al. Standards Track [Page 10] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + mplsTunnelRole = head (1), + -- Mandatory parameters needed to activate the row go here + mplsTunnelRowStatus = createAndGo (4) + } + + Note that any active or signaled instances of the above tunnel would + appear with the same primary mplsTunnelIndex, but would have values + greater than 0 for mplsTunnelInstance. They would also have other + objects such as the mplsTunnelXCPointer set accordingly. + +10. The Use of RowPointer + + RowPointer is a textual convention used to identify a conceptual row + in a conceptual table in a MIB by pointing to the first accessible + object. In this MIB module, in mplsTunnelTable, the objects + mplsTunnelXCPointer and mplsTunnelResourcePointer are of type + RowPointer. The object mplsTunnelXCPointer points to a specific + entry in the mplsXCTable [RFC3813]. This entry in the mplsXCTable is + the associated LSP for the given MPLS tunnel entry. The object + mplsTunnelResourcePointer points to a specific entry in a traffic + parameter table. An example of such a traffic parameter table is + mplsTunnelResourceTable. It indicates a specific instance of a + traffic parameter entry that is associated with a given MPLS tunnel + entry. These RowPointer objects MUST point to the first instance of + the first accessible columnar object in the appropriate conceptual + row in order to allow the manager to find the appropriate + corresponding entry in either MPLS-LSR-STD-MIB [RFC3813] or MPLS-TE- + STD-MIB. If object mplsTunnelXCPointer returns zeroDotZero, it + implies that there is no LSP associated with that particular instance + of tunnel entry. If object mplsTunnelResourcePointer returns + zeroDotZero, it implies that there is no QoS resource associated with + that particular instance of tunnel entry. + +11.

Security Considerations + + It is clear that this MIB module is potentially useful for the + monitoring of MPLS TE tunnels. This MIB module can also be used for + the configuration of certain objects, and anything that can be + configured can be incorrectly configured, with potentially disastrous + results. + + There are a number of management objects defined in this MIB module + with 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. These are the tables and objects and their + sensitivity/vulnerability: + + - the mplsTunnelTable, mplsTunnelHopTable, mplsTunnelResourceTable, + and mplsTunnelCRLDPResTable collectively contain objects to + provision MPLS tunnels, tunnel hops, and tunnel resources. + Unauthorized access to objects in these tables, could result in + disruption of traffic on the network. This is especially true if + a tunnel has been established. The use of stronger mechanisms, + such as SNMPv3 security, should be considered where possible. + Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent + which implements this MIB. Administrators should consider whether + read access to these objects should be allowed, since read access + may be undesirable under certain circumstances. + + 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 + + + + +Srinivasan, et al. Standards Track [Page 63] + +RFC 3812 MPLS-TE-STD-MIB June 2004 + + + 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: + + - the mplsTunnelTable, mplsTunnelHopTable, mplsTunnelResourceTable, + mplsTunnelARHopTable, mplsTunnelCHopTable, mplsTunnelPerfTable, + and mplsTunnelCRLDPResTable collectively show the MPLS-TE tunnel + network topology and its performance characteristics. 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), + 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 module. + + It is RECOMMENDED that implementers consider the security features as + provided by the SNMPv3 framework (see [RFC3410], section 8), + including full support for the SNMPv3 cryptographic mechanisms (for + authentication and privacy). + + Further, deployment of SNMP versions prior to SNMPv3 is NOT + RECOMMENDED. Instead, it is RECOMMENDED that SNMPv3 be deployed and + cryptographic security enabled. 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 + only those principals (users) that have legitimate rights to those + objects. + +13.
