This object contains the next appropriate value to be used for vRtrStaticFrrMplsOutSegmentIndex when creating entries in the vRtrStaticFrrMplsOutSegmentTable. If the number of unassigned entries is exhausted, this object will take on the value of 0. To obtain the vRtrStaticFrrMplsOutSegmentIndex value for a new entry, the manager must first issue a management protocol retrieval operation to obtain the current value of this object. The agent should modify the value to reflect the next unassigned index after each retrieval operation. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.
