       STATUS      current
       DESCRIPTION
           "The maximum transmission unit (MTU) that was negotiated
           or registered for this entity. In other words, this is the

       SYNTAX      Integer32 (0..255)
       MAX-ACCESS  read-create
       STATUS      current
       DESCRIPTION
           "An object which reflects the Preference value of the
           Client Information Entry (CIE).

           Zero or more Client Information Entries (CIEs) may be
           included in the NHRP Packet.  One of the fields in the
           CIE is the Preference.  For a complete description of
           the CIE, refer to Section 5.2.0.1 of  RFC 2332 [17]."

       DESCRIPTION
           "This value only has meaning when the 'nhrpCacheType'
           has the value of 'administrativelyAdded'.

           When the row is created due to being
           'administrativelyAdded', this object reflects whether
           this row is kept in volatile storage
           and lost upon reboot or if this row is backed up by
           non-volatile or permanent storage.

           If the value of 'nhrpCacheType' has a value which
           is not 'administrativelyAdded, then the value of this
           object is 'other(1)'."
