[j-nsp] How to load a lot of prefixes

[Keegan.Holley at sungard.com]

They were actually three different groups of a few thousand routes each. I 
had routers peered with different ISP AS numbers so that the origins would 
be realistic.  Even then the whole screen goes blank for about 30 seconds 
or so, but it makes it to the end eventually...  Besides this is just 
temporary until I complete that beginners course on sed.
