Re: large multi-site enterprises and PI prefix [Re: who gets a /32[Re: IPV6 renumbering painless?]]

Pekka,
All of the examples I referenced (which I unfortunately cannot name
due to NDA) fit exactly the model you are referring to. They advertise a small
number of prefixes from a small number of sites to cover a very large and
diverse number of sites. They advertise the same set of prefixes from the
same ASN in each of those sites. In cases where they are using VPN for
backbone, they use PA space for the VPN terminators and do not advertise
more specifics to accommodate this.

Hope that helps.

Owen

I'm not sure anyone is marginalizing them.

The point just is that are those very big, international networks
advertising the same aggregate in all the places they (publicly) connect
to the net, and no more specifics anywhere?

I.e., what I'd like to see is a couple of example of international big
enterprises which would not need to advertise the more specifics to
Internet anywhere.  How rare is this?
