             based routing protocol, based on the
             mplsTunnelHopTable for the outgoing direction of
             the tunnel. Thus at a transit LSR, this table (if
             the table is supported) MAY contain the path
             computed by the CSPF engine on (or on behalf of)
             this LSR. Each row in this table is indexed by
             mplsTunnelCHopListIndex.  Each row also has a
             secondary index mplsTunnelCHopIndex, corresponding
             to the next hop that this row corresponds to. In
             case we want to specify a particular interface on
             the originating LSR of an outgoing tunnel by which
             we want packets to exit the LSR, we specify this as
             the first hop for this tunnel in
             mplsTunnelCHopTable.

             build entries within this table may not be
             supported by some LSRs, implementation of this

12.  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

Top      Up      ToC       Page 64 
   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.

14.  IANA Considerations

   As described in [MPLSMGMT] and as requested in the MPLS-TC-STD-MIB
   [RFC3811], MPLS related standards track MIB modules should be rooted
   under the mplsStdMIB subtree.  There are 4 MPLS MIB Modules contained
   in this document, each of the following "IANA Considerations"
   subsections requests IANA for a new assignment under the mplsStdMIB
   subtree.  New assignments can only be made via a Standards Action as
   specified in [RFC2434].
