Re: A couple of possibly interesting stats.

The first table focuses on the current classful routes being passed around by AS
and the amount of gain CIDR would give *IF* we could aggregate as the AS level.
It shows the number of nets per AS so we see who is announcing what in terms of
BGP as well as what the number of CIDR nets would be advertised if we could
aggregate at this level...

	Tony,

	Interesting.  Just wonder if the would CIDR nets (aggregates) of each AS
	that you composed includes holes or not.  E.g.

	If AS1 has routes
	199.1.0 - 199.1.7 except 199.1.3.  
	What CIDR net does it count for this AS in your list:  

	a. 199.1.0/21 	(aggregate with hole and reduce routes from 7 to 1) or
	b. 199.1.0, 199.1.1, 199.1.2 & 199.1.4/22  (without hole and reduce
						routes from 7 to 4) 

	Basically, I like to know if this reduction of routes on your list (32.6%)
	is calculated with aggregates with holes or not.  If it does not
	include holes, we should be able to see a MORE reduction of the routing
	table size by doing the same analysis but include holes in the potential 
	aggregates.
