Don,

Because those routers you are managing has an interface in those
subnets...NetView MUST discover and put those on the map.   Those subnets
will only include router interfaces unless you "manage" them, then it will
do discovery within that subnet.

If you feel bogged down in your map by those, use the location.conf to put
those into a special "unmanaged subnet" location.   This should clean up
your map quite a bit.

Kind regards,
