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.
