That's the solution... OSPF will only summarize external routes that enter
the OSPF process... SO - you need to make the route that you want to
summarize appear to be external. Redistribute connected does this for you.
Pass it through a route-map so that you only get the network that you want.
You might also think about filtering the summary out of the OSPF domain...
