ah - then the numbers are much more compatible!

But that 1/5 number..... Why?

When I'm in big buildings, I usually see these fat bundles of Cat5 running 
from the panels in the offices to a central switching closet somewhere - 
10, 100 or even 1000 ports off the same switch.

In an 100:1 scenario, a 1000-end-node L2 network would have 10 bridges; in 
a 5:1 scenario, it would have 200 bridges. That makes an obvious difference 
to how far we have to make sure TRILL scales.
