[AusNOG] Write up - Big ISP, little ISP, local internet exchanges

[Matthew Moyle-Croft]

Edwin,
So, this design sounds like it wasn't for an Internet transit network, 
but an intranet?  ie. where global connectivity isn't necessarily 
needed?  In our world where we're providing full internet access I'm 
still not quite understanding how you do the filtering in this extra 
layer of complexity which you couldn't do in a traditional "single 
cloud" model. 

Can you give a specific example of using this model to stop this issue 
in an Internet transit network?
