            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

Nadeau, et al. Standards Track [Page 3] 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] RFC 6445 MPLS Fast-Reroute MIB November 2011

 They are:
  1. MPLS-FRR-GENERAL-STD-MIB: Contains objects that apply to any MPLS

LSR implementing MPLS TE fast-reroute functionality.

  1. MPLS-FRR-ONE2ONE-STD-MIB: Contains objects that apply to the

one-to-one backup method.

  1. 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.

Nadeau, et al. Standards Track [Page 5] RFC 6445 MPLS Fast-Reroute MIB November 2011

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
  mplsFrrGeneralConstraintsProtectionType = 1, -- linkProtection
  mplsFrrGeneralConstraintsSetupPrio      = 0,
  mplsFrrGeneralConstraintsHoldingPrio     = 0,
  mplsFrrGeneralConstraintsInclAnyAffinity = 0,
  mplsFrrGeneralConstraintsInclAllAffinity = 0,
  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.

Nadeau, et al. Standards Track [Page 6] RFC 6445 MPLS Fast-Reroute MIB November 2011

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:
  1. mplsTunnelIndex [RFC3812]: set to the Tunnel ID of an LSP protected

by a detour.

  1. 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.
  1. ingress node's LSR ID (mplsFrrOne2OnePlrTunnelIngressLSRId): set

to the ingress node of an LSP protected by a detour.

  1. 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.

Nadeau, et al. Standards Track [Page 7] 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.

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:
  1. mplsFrrOne2OnePlrTunnelIngressLSRId and

mplsFrrOne2OnePlrTunnelEgressLSRId objects of the

    mplsFrrOne2OnePlrTable
  1. mplsFrrOne2OnePlrTunnelIngressLSRId and

mplsFrrOne2OnePlrTunnelEgressLSRId objects of the

    mplsFrrOne2OneDetourTable

       "An entry in this table represents detour LSP or bypass
        tunnel setup constraints for an interface or link to be
        protected by detour LSPs or a bypass tunnel.
        Once the LSP or tunnel instance to be protected is identified
        in the mplsTunnelTable, the corresponding mplsTunnelIfIndex

Nadeau, et al. Standards Track [Page 17] RFC 6445 MPLS Fast-Reroute MIB November 2011

        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:
  1. lower 16 bits : protected tunnel instance
  2. higher 16 bits: must be all zeros"

         interface, protecting backup tunnel, and protected tunnel.
         MPLS interfaces defined on this node are protected by

         mplsFrrFacilityProtectedIfIndex.  If the interface index is

         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

         in this table MUST NOT be persistent, or the values of

         It is recommended that entries in this table be persistent

         The protecting tunnel is indicated by the

         represents a valid mplsTunnelEntry.  Note that the tunnel
         instance index of the protecting tunnel may be set to 0,

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] 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.

8.1. IANA Considerations for MPLS-FRR-GENERAL-STD-MIB

 IANA has assigned { mib-2 202 } to the MPLS-FRR-GENERAL-STD-MIB
 module specified in this document.

8.2. IANA Considerations for MPLS-FRR-ONE2ONE-STD-MIB

 IANA has assigned { mib-2 203 } to the MPLS-FRR-ONE2ONE-STD-MIB
 module specified in this document.

8.3. IANA Considerations for MPLS-FRR-FACILITY-STD-MIB

 IANA has assigned { mib-2 204 } to the MPLS-FRR-FACILITY-STD-MIB
 module specified in this document.
