This object contains an appropriate value to
be used for cpwVcMplsOutboundIndex when creating
entries in the cpwVcMplsOutboundTable. The value
0 indicates that no unassigned entries are
available. To obtain the cpwVcMplsOutboundIndex
value for a new entry, the manager issues a
management protocol retrieval operation to obtain
the current value of this object. After each
retrieval, the agent should modify the value to
the next unassigned index, however the agent MUST
NOT assume such retrieval will be done for each
row created.
