    nhrpNextIndex   OBJECT-TYPE
        SYNTAX      Unsigned32

        STATUS      current
        DESCRIPTION
            "This scalar is used for creating rows in the
            nhrpClientTable and the nhrpServerTable.
            The value of this variable is a currently unused value
            for nhrpClientIndex and nhrpServerIndex.

            The value returned when reading this variable must be
            unique for the NHC's and NHS's indices associated with
            this row. Subsequent attempts to read this variable
            must return different values.

            NOTE:  this object exists in the General Group because
            it is to be used in establishing rows in the
            nhrpClientTable and the nhrpServerTable.  In other words,
            the value retrieved from this object could become the
            value of nhrpClientIndex and nhprServerIndex.

            In the situation of an agent re-initialization the value
            of this object must be saved in non-volatile storage.

            This variable will return the special value 0 if no new
            rows can be created."

           "A cached mapping between an internetwork layer address
           and an NBMA address. Entries can be created by the
           network administrator using the nhrpCacheRowStatus

           protocol operation (including NHRP, SCSP, and others,
           such as ATMARP).

           When created based by NHRP protocol operations
           this entry is largely based on contents contained in
           the Client Information Entry (CIE).
