Specifies the maximum routing hops from the local node to any
 other reachable node. A hop is the logical distance over a line
 between two adjacent nodes.  Use as small a number as possible in
 the range of 1 to 31, and be sure that this value is less than or
 equal to the MAXIMUM VISITS parameter. If you receive an "INVALID
 VALUE" error, you probably have not allocated enough Non Paged
 Pool space.  You must lower the MAXIMUM HOPS value or increase
 the VMS NPAGEDYN value.  Refer to Chapter 5 of the Guide to
 Networking on for some guidelines on NPAGEDYN.
