rlInternInetStaticRouteNextHop
1.3.6.1.4.1.9.6.1.101.26.31.1.5
The next-hop IP address, if any.
If rlInternInetStaticRouteAction is 'forward', there may or may not be
a next-hop IP address.
A next-hop IP address is not required if an output interface
index is specified (in other words, if rlInternInetStaticRouteIfIndex is
non-zero).
If rlInternInetStaticRouteAction is not 'forward', there is no next-hop
IP address.
If there is no next-hop IP address, the rlInternInetStaticRouteNextHop
object is set to all zeroes.
