Nope, the route(1) is correct about it. Actually (and I think it is
provided for backwards compatibility, thus undocumented) the format is:
route [-n] command [-net | -host] destination gateway [netmask]
^^^^^^^
So, the
route -n add -net 10.150.200.0 255.255.252.0 10.125.200.199
is equivalent to the
route -n add -net 10.150.200.0 -netmask 10.125.200.199 255.255.252.0
You will get the same `weird' route in the second case.
To delete this route, simply execute:
route delete 10.20.200.0 -netmask 10.125.200.199
To add the correct route, either:
route add -net 10.150.200.0 -netmask 255.255.252.0 10.125.200.199
or
route add -net 10.150.200.0 10.125.200.199 255.255.252.0
or
route add 10.150.200.0/22 10.125.200.199
