        Multiprotocol Label Switching (MPLS) Traffic Engineering
              Management Information Base for Fast Reroute

Abstract

   This memo defines a portion of the Management Information Base for
   use with network management protocols in the Internet community.  In
   particular, it describes managed objects used to support two fast
   reroute (FRR) methods for Multiprotocol Label Switching (MPLS)-based
   traffic engineering (TE).  The two methods are the one-to-one backup
   method and the facility backup method.

RFC 6445                  MPLS Fast-Reroute MIB            November 2011


1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   containing objects used to manage Multiprotocol Label Switching
   (MPLS)-based fast rerouting features on MPLS Label Switching Routers
   (LSRs) as defined in [RFC4090].  The MIB modules defined in this
   document should be used in conjunction with [RFC3811], [RFC3812], and
   [RFC3813].

1.1.  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
   RFC 2119 [RFC2119].

2.  Terminology

   This document uses terminology from "Multiprotocol Label Switching
   Architecture" [RFC3031] and from "Fast Reroute Extensions to RSVP-TE
   for LSP Tunnels" [RFC4090].

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
   [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB module 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 MIB modules that are 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.  Overview of the MIB Modules

   [RFC4090] stipulates two different approaches to implementing MPLS TE
   fast reroute: one-to-one backup and facility backup.

   We define three MIB modules to represent the respective components:
   general, one-to-one backup, and facility backup.







Nadeau, et al.               Standards Track                    [Page 4]
^L
RFC 6445                  MPLS Fast-Reroute MIB            November 2011


   They are:

   -  MPLS-FRR-GENERAL-STD-MIB: Contains objects that apply to any MPLS
      LSR implementing MPLS TE fast-reroute functionality.

   -  MPLS-FRR-ONE2ONE-STD-MIB: Contains objects that apply to the
      one-to-one backup method.

   -  MPLS-FRR-FACILITY-STD-MIB: Contains objects that apply to the
      facility backup method.

   Although [RFC4090] specifies that a node is able to support both
   fast-reroute methods simultaneously, common practice has shown that
   operators choose to configure either the one-to-one backup method or
   the facility backup method at any given time.  So, by dividing the
   MIB modules into three, we allow the developers to choose the MIB
   modules they want to implement, depending on the method supported on
   that node.

4.1.  MPLS-FRR-GENERAL-STD-MIB

   This MIB module MUST be implemented if either of the fast-reroute
   methods is implemented.

4.1.1.  mplsFrrConstraintsTable

   This table contains objects that apply to all LSRs implementing MPLS
   TE fast-reroute functions.  In particular, this table defines fast-
   reroute constraints, such as bandwidth, for a tunnel instance to be
   protected by using backup Label Switched Paths (LSPs) (detour LSPs or
   bypass tunnels).

   This table MUST be implemented at the ingress node of the protected
   TE tunnel instance to configure backup LSP setup constraints.

4.1.2.  mplsFrrTunnelARHopTable

   This table extends mplsTunnelARHopTable (defined in the
   MPLS-TE-STD-MIB [RFC3812]) with fast-reroute objects that specify the
   local protection type or types of availability, as well as what type
   or types are actually in use for each tunnel hop traversed by a
   protected TE tunnel.

4.1.3.  Example of Relationship between Various Tables of
        MPLS-FRR-GENERAL-STD-MIB

              (R1)----(R2)----(R3)----(R4)---(R5)

                  (R6)---(R7)------(R8)

              Protected LSP:  [R1->R2->R3->R4->R5]

              R1's Backup:    [R1->R6->R7->R8->R3]

   In the above topology, the various tables on R1 will be populated as
   indicated below.

   mplsFrrGeneralConstraintsTable
   {
    mplsFrrGeneralConstraintsIfIndexOrZero  = 10,-- interface to protect
    mplsFrrGeneralConstraintsTunnelIndex    = 1, -- protecting tunnel
    mplsFrrGeneralConstraintsTunnelInstance = 0, -- use any instance

    mplsFrrGeneralConstraintsExclAnyAffinity = 0,
    mplsFrrGeneralConstraintsHopLimit        = 0,
    mplsFrrGeneralConstraintsBandwidth       = 0, -- best effort
    mplsFrrGeneralConstraintsStorageType     = 2, -- volatile
    mplsFrrGeneralConstraintsRowStatus       = 1, -- active
    };

   mplsFrrGeneralTunnelARHopEntry
   {
    mplsFrrGeneralTunnelARHopSessionAttributeFlags = 5,
                             -- sestyleDesired | localProtectionDesired
    mplsFrrGeneralTunnelARHopRROSubObjectFlags = 2
                             -- localProtectionInUse
    };

4.2.  MPLS-FRR-ONE2ONE-STD-MIB

   This MIB module MUST be implemented if the one-to-one backup fast-
   reroute method is implemented.

4.2.1.  mplsFrrOne2OnePlrTable

   The mplsFrrOne2OnePlrTable contains information about Points of Local
   Repair (PLRs) that initiated detour LSPs to protect tunnel instances.
   This table MUST be supported for LSRs implementing the one-to-one
   backup method.  In these cases, the detour LSPs are reflected in the
   mplsFrrOne2OneDetourTable.

4.2.2.  mplsFrrOne2OneDetourTable

   The mplsFrrOne2OneDetourTable shows the detour LSPs in each node
   (ingress, transit, and egress nodes).  An entry in this table
   represents a detour LSP.

   Each detour is identified by the following indexes:

   - mplsTunnelIndex [RFC3812]: set to the Tunnel ID of an LSP protected
     by a detour.

   - mplsTunnelInstance [RFC3812]: consists of two parts:

        1) the higher 16 bits:  - protected TE tunnel instance
                                - uniquely identifies a protected
                                  LSP within a tunnel.

        2) the lower 16 bits:   - detour instance
                                - uniquely identifies a detour LSP
                                  of a protected TE tunnel instance.
                                  Multiple detours of the same
                                  protected LSP may go through the
                                  same node.  In this case, the
                                  higher 16 bits of the tunnel
                                  instance object is used as a
                                  detour instance.

   -  ingress node's LSR ID (mplsFrrOne2OnePlrTunnelIngressLSRId): set
      to the ingress node of an LSP protected by a detour.

   -  egress node's LSR ID (mplsFrrOne2OnePlrTunnelEgressLSRId): set to
      the egress node of an LSP protected by a detour.

   A detour LSP is also considered as an instance of a protected TE
   tunnel.  Therefore, each detour LSP SHOULD have an entry in the
   mplsTunnelTable (defined in the MPLS-TE-STD-MIB [RFC3812]).

   The mplsTunnelTable entries are indexed using mplsTunnelIndex,
   mplsTunnelInstance, mplsTunnelIngressLSRId, and
   mplsTunnelEgressLSRId.

^L
RFC 6445                  MPLS Fast-Reroute MIB            November 2011


   Entries where the higher 16 bits of mplsTunnelInstance are set to
   zero represent detour TE tunnel instances.  All other values of the
   higher 16 bits represent protected tunnel instances.

   This table MUST be supported if the one-to-one backup method is used.

4.2.3.  Example of Relationship between mplsFrrOne2OnePlrTable,
        mplsFrrOne2OneDetourTable, and mplsTunnelTable

   This section contains an example depicting the interrelationship
   between mplsFrrOne2OnePlrTable, mplsFrrOne2OneDetourTable, and
   mplsTunnelTable.

              (R1)----(R2)----(R3)----(R4)---(R5)
                  \       \       \    /
                  (R6)---(R7)------(R8)

              Protected LSP:  [R1->R2->R3->R4->R5]

              R1's Backup:    [R1->R6->R7->R8->R3]

   In the above topology, the various tables will be populated as

4.3.  MPLS-FRR-FACILITY-STD-MIB

   This MIB module MUST be implemented if the facility backup
   fast-reroute method is implemented.

4.3.1.  mplsFrrFacilityDBTable

   The mplsFrrFacilityDBTable provides information about the fast-
   reroute database for facility-based fast reroute.

   An entry is created in this table for each tunnel being protected by
   a backup tunnel.  Backup tunnels are defined to protect the tunnels
   traversing an interface.

   The protecting tunnel will exist on the PLR as per [RFC4090].
   Protected tunnels are the LSPs that traverse the protected link.

5.  Handling IPv6 Tunnels

   As described in [RFC4990], in order to support IPv6 MPLS tunnels in
   the mplsTunnelTable [RFC3812], all LSRs in the network MUST have a
   32-bit LSR ID that can be used to identify the LSR with the existing
   mplsTunnelIngressLSRId and mplsTunnelEgressLSRId objects, which are
   32 bits long.

   In this MIB, the following objects, which refer to ingress/egress
   LSRs, will therefore have the 32-bit LSR ID to support IPv6 tunnels:

   -  mplsFrrOne2OnePlrTunnelIngressLSRId and
      mplsFrrOne2OnePlrTunnelEgressLSRId objects of the
      mplsFrrOne2OnePlrTable

   -  mplsFrrOne2OnePlrTunnelIngressLSRId and
      mplsFrrOne2OnePlrTunnelEgressLSRId objects of the
      mplsFrrOne2OneDetourTable

          value of that tunnel can be used to get the ifIndex of
          the underlying physical interface using the ifStackTable.
          That ifIndex of the underlying physical interface will
          be used as mplsFrrGeneralConstraintsIfIndexOrZero in this
          table to protect the LSPs or tunnel instances determined
          earlier.

          It is recommended that ifIndex persistence be enabled
          across re-initializations.  If persistence is not
          implemented, then the value of
          mplsFrrGeneralConstraintsIfIndexOrZero in this
          table cannot be guaranteed across restarts and all entries
          in this table MUST NOT be persistent, or the values of
          mplsFrrGeneralConstraintsIfIndexOrZero MUST be reconstructed
          on restart.

          SNMP engines must only allow entries in this table
          to be created for tunnel instances that require fast reroute
          as indicated by the presence of the FAST_REROUTE object
          in the signaling for the LSP in question.

          An entry in this table can be created only if a
          corresponding entry in mplsTunnelTable exists with the
          same mplsTunnelIndex as mplsFrrGeneralConstraintsTunnelIndex.

          Entries in this table are deleted when the corresponding
          entries in mplsTunnelTable are deleted.

          It is recommended that entries in this table be persistent
          across reboots.

          Entries indexed with mplsFrrGeneralConstraintsIfIndexOrZero
          and set to 0 apply to all interfaces on this device for
          which the FRR feature can operate.

          If the mplsTunnelInstance object is set to a value of 0,
          it indicates that the mplsTunnelEntry contains a tunnel
          ingress.  This is typically how configuration of this
          feature is performed on devices where the actual
          protection LSP used is left up to the protecting tunnel.
          However, in cases where static configuration is
          possible, any valid tunnel instance is possible;
          however, it is strongly RECOMMENDED that the instance
          index SHOULD use the following convention to identify
          backup LSPs:

          - lower 16 bits : protected tunnel instance
          - higher 16 bits: must be all zeros"

         "Uniquely identifies an existing instance of this tunnel
          for which fast reroute is requested.  Note that a value of
          0 indicates that the configuration points at a tunnel
          head (as specified in RFC 3812).  This is typically how
          configuration of this feature is performed on devices
          where the actual protection LSP used is left up to the
          protecting tunnel.  However, in cases where static
          configuration is possible, any valid tunnel instance is
          permissible.  In these cases, it is recommended that the
          instance index follow the following convention so as
          to make identification of backup LSPs easier:

          - lower 16 bits : protected tunnel instance
          - higher 16 bits: must be all zeros"

           interface, protecting backup tunnel, and protected tunnel.
           MPLS interfaces defined on this node are protected by
           backup tunnels and are indicated by the index
           mplsFrrFacilityProtectedIfIndex.  If the interface index is
           set to 0, this indicates that the remaining indexes apply
           to all configured protected interfaces.

           Note that all objects in this table are read-only, and
           if new objects are added to this table, they should also
           be read-only.

           It is recommended that ifIndex persistence be enabled
           across re-initializations.
           If persistence is not implemented, then the value of
           mplsFrrFacilityProtectedIfIndex in this
           table cannot be guaranteed across restarts and all entries
           in this table MUST NOT be persistent, or the values of
           mplsFrrFacilityProtectedIfIndex MUST be reconstructed
           on restart.

           It is recommended that entries in this table be persistent
           across reboots.

           The protecting tunnel is indicated by the
           index mplsFrrFacilityProtectingTunnelIndex and
           represents a valid mplsTunnelEntry.  Note that the tunnel
           instance index of the protecting tunnel may be set to 0,
           which indicates the tunnel head interface for the
           protecting tunnel, as per RFC 3812, but it may also be
           defined using the following semantics:

          of '1,000 bits per second', actually reserved by
          the protecting tunnel for facility backup purposes.
          This value is repeated here from the MPLS-TE-STD-MIB
          module because the tunnel entry will reveal the
          bandwidth reserved by the signaling protocol, which is
          typically 0 for backup tunnels so as to not over-book
          bandwidth.  However, internal reservations are
          typically made on the PLR; thus, this value should be
          revealed here, as it is often different from
          mplsTunnelResourceMeanRate found in the MPLS-TE-STD-MIB
          module."

          be a difference between when the control plane triggers
          this notification and when the hardware is programmed to
          utilize the protection path.  Due to the urgency of this
          operation, it is acceptable for the control plane to
          issue this notification either before or after it programs
          the hardware.  In cases where it is the latter approach,
          the notification MUST be sent immediately after the
          data plane has been altered.

          This notification should not be generated for each subsequent
          tunnel that is backed up by the FRR feature on this LSR, as
          this may result in potential scaling issues with regard to

7.  Security Considerations

   It is clear that these MIB modules are potentially useful for the
   monitoring of MPLS LSRs supporting fast reroute.  These MIB modules
   can also be used for configuration of certain objects; note that
   anything that can be configured can be incorrectly configured, with
   potentially disastrous results.

   There are a number of management objects defined in these MIB modules
   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:

   o  The mplsFrrGeneralConstraintsTable
      (mplsFrrGeneralConstraintsProtectionType,
      mplsFrrGeneralConstraintsSetupPrio, etc.), and some objects in the
      mplsFrrScalarGroup (mplsFrrGeneralProtectionMethod,
      mplsFrrFacilityNotificationsEnabled, etc.) contain objects that
      may be used to provision MPLS fast-reroute features.  Unauthorized
      access to these objects could result in disruption of traffic on
      the network.






Nadeau, et al.               Standards Track                   [Page 49]
^L
RFC 6445                  MPLS Fast-Reroute MIB            November 2011


   Some of the readable objects in these MIB modules (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:

   o  The mplsFrrOne2OnePlrTable (mplsFrrOne2OnePlrSenderAddr,
      mplsFrrOne2OnePlrAvoidNodeAddr, etc.), mplsFrrOne2OneDetourTable
      (mplsFrrOne2OneDetourActive, mplsFrrOne2OneDetourMergedDetourInst,
      etc.), and mplsFrrGeneralTunnelARHopTable
      (mplsFrrGeneralTunnelARHopSessionAttributeFlags,
      mplsFrrGeneralTunnelARHopRROSubObjectFlags, etc.), and some
      objects contained in the mplsFrrScalarGroup
      (mplsFrrGeneralProtectionMethod, mplsFrrActiveInterfaces, etc.),
      collectively show the MPLS fast-reroute interfaces, tunnels, and
      other associated fast-reroute feature configurations as well as
      their linkages to other MPLS-related configuration and/or
      performance statistics.  Administrators not wishing to reveal this
      information should consider these objects sensitive/vulnerable and
      take precautions so they are not revealed.

   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 these MIB modules.

   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 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 these MIB modules 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.

8.  IANA Considerations

   The MIB modules in this document use the IANA-assigned OBJECT
   IDENTIFIER values recorded in the SMI Numbers registry.
