  DESCRIPTION

    "The gmplsTunnelTable sparsely extends the mplsTunnelTable of

     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."

       protection scheme, such as 1:N protection, should be used to

  DESCRIPTION

    "The gmplsTunnelARHopTable sparsely extends the

     mplsTunnelARHopTable of MPLS-TE-STD-MIB.  It is used to

     indicate the labels currently in use for a GMPLS tunnel

     defined in the mplsTunnelTable and gmplsTunnelTable, as

     reported by the signaling protocol.  It does not insert

     new hops, but does define new values for hops defined in

     the mplsTunnelARHopTable.

     Each row in this table is indexed by the same indexes as in the

     mplsTunnelARHopTable.  It is acceptable for some rows in the

     mplsTunnelARHopTable to have corresponding entries in this table

     and some to have no corresponding entry in this table.

     Note that since the information necessary to build entries

     within this table is not provided by some signaling protocols

     and might not be returned in all cases of other signaling

     protocols, implementation of this table and the

     mplsTunnelARHopTable is optional.  Furthermore, since the

     information in this table is actually provided by the

     signaling protocol after the path has been set up, the entries

     in this table are provided only for observation, and hence,

     all variables in this table are accessible exclusively as

     read-only."

  DESCRIPTION

    "An entry in this table represents additions to a tunnel hop

     visible in mplsTunnelARHopEntry.  An entry is created by the

     signaling protocol for a signaled ERLSP set up by the signaling

     protocol.

     At any node on the LSP (ingress, transit, or egress), this table

     and the mplsTunnelARHopTable (if the tables are supported and if

     the signaling protocol is recording actual route information)

     contain the actual route of the whole tunnel.  If the signaling

     protocol is not recording the actual route, this table MAY

     report the information from the gmplsTunnelHopTable or the

     gmplsTunnelCHopTable.

     Note that the recording of actual labels is distinct from the

     recording of the actual route in some signaling protocols.  This

     feature is enabled using the gmplsTunnelAttributes object."
