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 as defined in [RFC4090]. This MIB module should
   be used in conjunction with [RFC3811], [RFC3812] and [RFC3813].

   Comments should be made directly to the MPLS mailing list at
   mpls@ietf.org.

1.1.  Conventions Used in This Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this

2.  Terminology

                 MPLS Fast-reroute MIB                June 27, 2008 






   This document uses terminology from the document describing the
   Multiprotocol Label Switching Architecture [RFC3031] and from
   the document describing 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 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. Overview of the MIB Module

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

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

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



Nadeau, et al.                Expires Dec 2008               [Page 3]

                 MPLS Fast-reroute MIB                June 27, 2008 






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 LSPs (detour LSPs or bypass tunnels).

      This table is used 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 which
      specify the local protection type or types of availability
      as well as what type or types are actally in-use for each
      tunnel hop traversed by a protected TE tunnel.

      The support of this table is only required when the
      Record Route Object (RRO) is supported by the implementation.

4.2. MPLS-FRR-ONE2ONE-STD-MIB

4.2.1 mplsFrrOne2OnePlrTable

      The mplsFrrOne2OnePlrTable contains information about PLRs that
      initiated detour LSPs to protect tunnel instances. This table
      is mandatory 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 of 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 lower 16 bits:  - protected TE tunnel instance
                               - uniquely identifies a protected
                                 LSP within a tunnel.



Nadeau, et al.                Expires Dec 2008               [Page 4]

                 MPLS Fast-reroute MIB                June 27, 2008 





        2) the higher 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 (mplsFrrOne2OnePlrTunIngrLSRId):
        set to the ingress node of an LSP protected by a detour.

      - egress node's LSR ID (mplsFrrOne2OnePlrTunEgrLSRId):
        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]).

      In the mplsTunnelTable, the higher 16 bits of the tunnel instance
      SHOULD be used as a detour instance. Note that for the protected
      TE tunnel instances, the higher 16 bits of the tunnel instance
      MUST all be set to zero.

      This table is mandatory if one-to-one backup method is used.

4.3 MPLS-FRR-FACILITY-STD-MIB

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 defined
      to protect the tunnels traversing an interface.
      The protecting tunnel is defined to exist on the PLR in
      the MPLS TE fast reroute specification.  Protected tunnels are
      the LSPs that traverse the protected link.

      Implementation of this table is mandatory when facility backup is
      used.

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



Nadeau, et al.                Expires Dec 2008               [Page 5]

                 MPLS Fast-reroute MIB                June 27, 2008 





    objects which are 32-bit long.

    In this MIB, the following objects which refer to ingress/egress
    LSRs will have then the 32-bit LSR ID to support IPv6 tunnels:
    - mplsFrrOne2OnePlrTunIngrLSRId and
    - mplsFrrOne2OnePlrTunEgrLSRId
      objects of the mplsFrrOne2OnePlrTable,
    - mplsFrrOne2OnePlrTunIngrLSRId and
    - mplsFrrOne2OnePlrTunEgrLSRId
      objects of the mplsFrrOne2OneDetourTable
    - mplsFrrFacilityBackupTunnelIngressLSRId and
    - mplsFrrFacilityBackupTunnelEgressLSRId
      objects of the mplsFrrFacilityDBTable

7. Security Considerations

   It is clear that these MIB modules are potentially useful for
   monitoring of MPLS LSRs supporting fast reroute.  This
   MIB module can also be used for configuration of certain objects,



Nadeau, et al.               Expires Dec 2008               [Page 39]

                 MPLS Fast-reroute MIB                June 27, 2008 





   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:

   o    the mplsFrrConstraintsTable and some objects in the
        mplsFrrScalarGroup contain objects which may be used
        to provision MPLS fast reroute features.  Unauthorized
        access to these objects could result in disruption of
        traffic on the network.  This is especially true if the
        objects in question refer to previously provisioned protection
        tunnels and configuration. 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 module.  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
   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, mplsFrrOne2OneDetourTable, and
        mplsFrrTunnelARHopTable tables and some objects
        contained in the mplsFrrScalarGroup
        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



Nadeau, et al.               Expires Dec 2008               [Page 40]

                 MPLS Fast-reroute MIB                June 27, 2008 





   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 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.

8.  IANA Considerations

   As described in the MPLS-TC-STD-MIB [RFC3811] MIB module, MPLS
   related standards track MIB modules should be rooted under the
   mplsStdMIB subtree. There is one MPLS-related
   MIB module contained in this document. The following "IANA
   Considerations" subsection requests IANA for a new assignment under
   the mplsStdMIB subtree.  New assignments can only be made via a
   Standards Action as specified in [RFC5226].

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

   The IANA is requested to assign { mplsStdMIB 12 } to the
   MPLS-FRR-STD-MIB MIB module specified in this document.
