  MAX-ACCESS not-accessible

  DESCRIPTION
    "The gmplsTunnelTable sparsely extends the mplsTunnelTable of
     MPLS-TE-STD-MIB.  It allows GMPLS tunnels to be created between
     an LSR and a remote endpoint, and existing tunnels to be
     reconfigured or removed.

     Note that only point-to-point tunnel segments are supported,
     although multipoint-to-point and point-to-multipoint
     connections are supported by an LSR acting as a cross-connect.
     Each tunnel can thus have one out-segment originating at this
     LSR and/or one in-segment terminating at this LSR.

     The row status of an entry in this table is controlled by the
     mplsTunnelRowStatus in the corresponding entry in the
     mplsTunnelTable.  When the corresponding mplsTunnelRowStatus has
     value active(1), a row in this table may not be created or
     modified.

     The exception to this rule is the
     gmplsTunnelAdminStatusInformation object, which can be modified
     while the tunnel is active."

     shared
       This flag is set to indicate that a shared link layer
       protection scheme, such as 1:N protection, should be used to
       support the LSP.

     dedicatedOneToOne
       This flag is set to indicate that a dedicated link layer
       protection scheme, i.e., 1:1 protection, should be used to

       take.  This path may contain strict or loose hops.
       Evaluation of the explicit route will be performed
       hop by hop through the network.

     dynamicPartial
       The user specifies at least the source and
       destination of the path and expects that the CSPF
       will calculate the remainder of the path.  The path
       computed by CSPF is allowed to be only partially
       computed allowing the remainder of the path to be
       filled in across the network.

     When an entry is present in the gmplsTunnelTable for a
     tunnel, gmplsTunnelPathComp MUST be used and any
     corresponding mplsTunnelHopEntryPathComp object in the

     The storage type for this entry is given by the value

     mplsTunnelHopTable.

     The row status of an entry in this table is controlled by
