Obviously, the way to save the most numbers is to advertise each route
separately.
However, if "in the fewest commands possible"...
Binary, don't fail me now!!!
20 = 00010100
28 = 00011000
36 = 00100100
44 = 00101100
Longest match is the first two of the 8bit binary number = 192
So I would say 192.168.0.0 255.255.192.0 is the supernet and mask.
in ospf: network 192.168.0.0 0.0.63.255 area X
If two commands were permitted...
192.168.0.0 255.255.224.0 and 192.168.32.0 255.255.240.0
Did I fail binary math?
