OK, I think I got it.
/15 doesn't make sense if I want to pick up just a 10.2.0.0 network because
it would also pick up a 10.3.0.0 network.
/16 will work if its the intent to summarize at 10.2.0.0, however that over
summarizes if its not our intent to pick up 10.2.0.0
Therefore the three

I want to summarize three addresses within an OSPF area:
10.2.1.0/24
10.2.2.0/24
10.2.3.0/24
Converting to binary, I see the 15th bit is the highest order bit the three
addresses have in common. From that I see the summary address

Actually, the 22nd bit is the highest common bit.
10.2.0001.0
10.2.0010.0
10.2.0011.0
The longest summary for this would be 10.2.0.0 /22
