The value of vRtrMplsGeneralNewP2mpInstIndex specifies the object that is used to assign
values to vRtrMplsP2mpInstIndex as described in 'Textual Conventions for SNMPv2'. The
network manager reads the object, and then writes the value back in the SET request that
creates a new instance of vRtrMplsP2mpInstEntry. If the SET fails with the code
'inconsistentValue', then the process must be repeated. If the the SET succeeds, then the
object is incremented and the new instance is created according to the manager's
directions.
