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=20
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

If it wasn't crypto-signed, it probably didn't come from me.
