Description: This object contains the next available valid value to be used for mplsFTNIndex when creating entries in the mplsFTNTable.

When creating a new conceptual row (configuration entry) in mplsFTNTable with an SNMP SET operation the command generator (Network Management Application) must first issue a management protocol retrieval operation to obtain the current value of this object.

If the Command Responder (agent) does not wish to allow creation of more entries in mplsFTNTable, possibly because of resource exhaustion, this object MUST return a value of 0.

If a non-zero value is returned it must determine whether the value is indeed still unused since two Network Management Applications may attempt to create a row simultaneously and use the same value.

If it is currently unused and the SET succeeds, the agent MUST change the value of this object to a currently unused non-zero value (according to an implementation specific algorithm) or zero (if no further row creation will be permitted).

If the value is in use, however, the SET fails and the Network Management Application must then reread this object to obtain a new usable value.
