I would think your mask would be more like /22 than /15
Do you really want to summarize at the /15 boundary? 10.0.0.0/15 might be
it.

Subject: Route Summarization [7:1794]
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 is 10.2.0.0.
What I don't understand is why the subnet mask is 16bits. To me it looks
like it should be 15.
Thanks,
Steve
