"This scalar is used for creating rows in the

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."

this entry is largely based on contents contained in
the Client Information Entry (CIE).
Zero or more Client Information Entries (CIEs) may be
included in the NHRP Packet. For a complete description
of the CIE, refer to Section 5.2.0.1 of
