Most (all) large ISP's have a "customer ASN". This allows a customer to connect in multiple places, run BGP, and get something approximating real redundancy to that carrier. However, rather than allocate one ASN to each customer, all customers use the same "customer ASN". Yes, that means they must default to the provider (and/or have the provider provide a default route) to reach the other customers using this technique.
Perhaps I'm missing something having not done this myself but why arent the customers just using private ASNs? That would also remove the 'must default' clause. Steve
