As far as the summarization vs. supernetting thing - here goes. Summarization is a general idea where several more specific routes are coupled - aggregated if you will - into a less general route with a shorter subnet mask. This can be (but does not have to be) performed by supernetting , which is basically a play on the whole classful route categories. When you choose to present a route that falls into one of the old alphabetical classes (A,B,C), but that route has a subnet mask that is shorter than indicated by that class, you are performing supernetting. Supernetting can be used as a specific kind of summarization. But summarization need not be performed by supernetting. But, sir, exactly when the hell did I imply that summarization always equated to supernetting? Only in my network would that be the case, because of the particular addresing scheme in use. Why won't we take this off-line, and just deal with each other directly from now on, buddy? No need to waste everybody else's time with this.
