Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for Multi-Protocol Label Switching (MPLS) [MPLSArch] based traffic engineering. 1. Introduction This memo defines an experimental portion of the Management Information Base (MIB) for use with network management Srinivasan et al. Expires May 2001 [Page 1] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 protocols in the Internet community. In particular, it describes managed objects for modeling a Multi-Protocol Label Switching (MPLS) [MPLSArch] based traffic engineering. This MIB should be used in conjunction with the companion document [LSRMIB] for MPLS based traffic engineering configuration and management. Comments should be made directly to the MPLS mailing list at mpls@uu.net. This memo does not, in its draft form, specify a standard for the Internet community. 2. Terminology This document uses terminology from the MPLS architecture document [MPLSArch] and MPLS Label Switch Router MIB [LSRMIB]. Some frequently used terms are described next. An explicitly routed LSP (ERLSP) is referred to as an MPLS tunnel. It consists of one in-segment and/or one out- segment at the ingress/egress 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 in performed using a cross-connect. These objects are defined in the MPLS Label Switch Router MIB [LSRMIB]. 3. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: - An overall architecture, described in RFC 2271 [SNMPArch]. - 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 RFC 1155 [SMIv1], RFC 1212 [SNMPv1MIBDef] and RFC 1215 [SNMPv1Traps]. The second version, called SMIv2, is described in RFC 1902 [SMIv2], RFC 1903 [SNMPv2TC] and RFC 1904 [SNMPv2Conf]. - Message protocols for transferring management information. The first version of the SNMP message Srinivasan et al. Expires May 2001 [Page 2] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 protocol is called SNMPv1 and described in RFC 1157 [SNMPv1]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [SNMPv2c] and RFC 1906 [SNMPv2TM]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [SNMPv2TM], RFC 2272 [SNMPv3MP] and RFC 2574 [SNMPv3USM]. - Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in RFC 1157 [SNMPv1]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [SNMPv2PO]. - A set of fundamental applications described in RFC 2273 [SNMPv3App] and the view-based access control mechanism described in RFC 2575 [SNMPv3VACM]. 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. 3.1. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to also refer to the object type. Srinivasan et al. Expires May 2001 [Page 3] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 4. Feature List The MPLS traffic engineering MIB is designed to satisfy the following requirements and constraints. - The MIB 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 supports manually configured MPLS tunnels as well as those set up via any MPLS signaling protocol. - The MIB 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 loose and strict source routed hops. These actions may need to be accompanied with corresponding actions using [LSRMIB] to establish and configure tunnel segments, if this is done manually. Also, the in-segment and out-segment performance tables, mplsInSegmentPerfTable and mplsOutSegmentPerfTable [LSRMIB], should be used to determine performance of the tunnels and tunnel segments. 5.1. Summary of Traffic Engineering MIB The MIB 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 hop table (mplsTunnelHopTable) for configuring strict and loose source routed MPLS tunnels hops. Srinivasan et al. Expires May 2001 [Page 4] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 When a tunnel is signaled via a MPLS signaling protocol, the mplsTunnelARHopTable gives the actual list of hops traversed by the tunnel as reported by the signaling protocol. 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 [RSVPTun][CR-LDP]. 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 tunnel segments, although multi- point-to-point and point-to-multi-point 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. 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 [LSRMIB]. 6.2. mplsTunnelResourceTable mplsTunnelResourceTable is used to indicate the resources required for a tunnel. Multiple tunnels may share the same resource by pointing to the same entry in this table. Tunnels that do not share resource 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 signaling. Multiple tunnels may share the same hops by pointing to the same entry in this Srinivasan et al. Expires May 2001 [Page 5] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 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. 6.4. mplsTunnelARHopTable mplsTunnelARHopTable is used to indicate the actual hops traversed by a tunnel as reported by the MPLS signaling protocol after the tunnel is setup. The support of this table is optional since not all MPLS signaling protocol may support this feature. 6.5. mplsTunnelCHoptable mplsTunnelCHopTable lists the actual hops computed by a constraint-based routing algorithm based on the mplsTunnelHopTable. The support of this table is optional since not all implementations may support computation of hop list using a constraint-based routing protocol. 6.6. mplsTunnelPerfTable mplsTunnelPerfTable provides several counters to measure the performance of the MPLS tunnels. This table auguments mplsTunnelTable. 7. 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 [IFMIB] 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 interface is considered an interface. Thus, the MPLS interface is represented as an entry in the ifTable. The interrelation of entries in the ifTable is defined by Interfaces Stack Group defined in [IFMIB]. When using MPLS Tunnels as interfaces, the interface stack Srinivasan et al. Expires May 2001 [Page 6] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 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, which has been defined for MPLS interworking. Examples include ATM, Frame Relay, Ethernet, etc. 7.1. Support of the MPLS Tunnel Interface by ifTable Some specific interpretations of 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 MPLS tunnel is 150. ifSpeed The total bandwidth in bits per second for use by the MPLS tunnel. ifPhysAddress Unused. ifAdminStatus See [IFMIB]. ifOperStatus Assumes the value down(2) if the MPLS tunnel is down. ifLastChange See [IFMIB]. ifInOctets The number of octets received over the MPLS tunnel. ifOutOctets The number of octets transmitted over the MPLS tunnel. Srinivasan et al. Expires May 2001 [Page 7] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 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 [IFMIB]. 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 [IFMIB]. ifHCInOctets The 64-bit version of ifInOctets; supported if required by the compliance statements in [IFMIB]. ifHCOutOctets The 64-bit version of ifOutOctets; supported if required by the compliance statements in [IFMIB]. ifAlias The non-volatile 'alias' name for the MPLS tunnel as specified by a network manager. 8. 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. In mplsTunnelTable: { mplsTunnelIndex = 1, mplsTunnelInstance = 1, mplsTunnelIngressLSRId = 123.123.125.1, mplsTunnelEgressLSRId = 123.123.126.1, mplsTunnelName = "My first tunnel", Srinivasan et al. Expires May 2001 [Page 8] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 mplsTunnelDescr = "Here to there", mplsTunnelIsIf = true (1), mplsTunnelXCPointer = mplsXCIndex.2.0.0.15, mplsTunnelSignallingProto = none (1), mplsTunnelSetupPrio = 0, mplsTunnelHoldingPrio = 0, mplsTunnelSessionAttributes = 0, mplsTunnelOwner = snmp (1), mplsTunnelLocalProtectInUse = false (0), mplsTunnelResourcePointer = mplsTunnelResourceIndex.5, mplsTunnelInstancePriority = 1, mplsTunnelHopTableIndex = 1, mplsTunnelPrimaryInstance = 0, mplsTunnelIncludeAnyAffinity = 0, mplsTunnelIncludeAllAffinity = 0, mplsTunnelExcludeAllAffinity = 0, mplsTunnelPathInUse = 1, mplsTunnelRole = head(1), mplsTunnelRowStatus = createAndGo (4) } In mplsTunnelResourceTable: { mplsTunnelResourceIndex = 5, mplsTunnelResourceMaxRate = 0, mplsTunnelResourceMeanRate = 0, mplsTunnelResourceMaxBurstSize = 0, 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 network, or the first hop. We have used the fictitious LSR identified by "123.123.125.1" as our example head-end router. In mplsTunnelHopTable: { mplsTunnelHopListIndex = 1, mplsTunnelPathOptionIndex = 1, mplsTunnelHopIndex = 1, mplsTunnelHopAddrType = 1, mplsTunnelHopIpv4Addr = 123.123.125.1, mplsTunnelHopIpv4PrefixLen = 9, mplsTunnelHopType = loose (2), mplsTunnelHopRowStatus = createAndGo (4) } The following denotes the end of the network, or the last Srinivasan et al. Expires May 2001 [Page 9] Internet Draft MPLS Traffic Engineering MIB 21 November 2000 hop in our example. We have used the fictitious LSR identified by "123.123.126.1" as our end router. In mplsTunnelHopTable: { mplsTunnelHopListIndex = 1, mplsTunnelPathOptionIndex = 1, mplsTunnelHopIndex = 2, mplsTunnelHopAddrType = 1, mplsTunnelHopIpv4Addr = 123.123.126.1, mplsTunnelHopIpv4PrefixLen = 9, mplsTunnelHopType = loose (2), mplsTunnelHopRowStatus = createAndGo (4) } 9. The Use of RowPointer RowPointer is a textual convention used to identify a conceptual row in an SNMP Table by pointing to one of its objects. In this MIB, in mplsTunnelTable, the objects mplsTunnelXCPointer and mplsTunnelResourcePointer are of type RowPointer. The object mplsTunnelXCPointer points to a specific entry in the mplsXCTable [LSRMIB]. 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. 10.

The following describes these bitfields: fastRerouteThis flag indicates that the any tunnel hop may choose to reroute this tunnel without tearing it down. This flag permits transit routers to use a local repair mechanism which may result in violation of the explicit routing of this tunnel. When a fault is detected on an adjacent downstream link or node, a transit router can reroute traffic for fast service restoration. mergingPermitted This flag permits transit routers to merge this session with other RSVP sessions for the purpose of reducing resource overhead on downstream transit routers, thereby providing better network scalability. isPersistent Indicates whether this tunnel should be restored automatically after a failure occurs. isPinned This flag indicates whether the loose- routed hops of this tunnel are to be pinned. isComputed This flag indicates whether the tunnel path is computed using a constraint-based routing algorithm based on the mplsTunnelHopTable entries. recordRoute This flag indicates whether or not the signaling protocol should remember the tunnel path after it has been signaled."

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. 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 [IPSEC]), 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 [SNMPv3USM] and the View- based Access Control [SNMPv3VACM] 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. 12.
