I don't see the point behind this, you would create even
*more* table entries with this approach.

There is operator A with customers in Paris, London and Berlin
and operator B with customers in London, Manchester and Birmingham.

Result: 6 Prefixes instead of 2.

Why: Operator networks are *not* interconnected in regional
area categories and prefer internal and peer routes instead
of regional upstreams.

Sorry, I don't see this as an solution.

This is the old Telco approach which works with *one*
main operator in Paris, one in London etc.

It does not work in a market with non-regional variable
interconnections.

E.g. we prefer to receive our traffic for Stuttgart in Munich
or Frankfurt, because in Stuttgart there is no international
exchange.

Ceterum Censeo:
Routing capacity can only be replaced by routing capacity.

Someone has to *calculate* the best path for the IP packets
and this someone is called "router". Either it can handle the
address space or it cannot, in the second case IPv6 is
*useless*.

The point:
There is no way to make a 1 H.P. 1900 car competitive in
a Formula One race.
