Since, you have presented examples routed through 3300 I felt it was ok to
comment this. We have experinced that customers of ours sometimes later
purchased a connection from another ISP keeping the connection to us.
Therefor will all allocation of address space to that customer no longer be
aggregated by us. Even if we know that this customer in most cases has
customers of his own, we usually don't reserve blocks for him. Well, you see
the result in the routing table. I thought in the beginning of CIDR that I
would never had to announce anything but 194.16/13. For connectivity reasons
this is not possible.
The only solution might be that every network that later becomes an AS has
to renumber the complete network (and it's customers also). In addition to
that he has to become a Local Internet Registry with his own address space.
One AS, one registry....
