An AS is a collection of prefixes with a consistent and common routing policy. By definition, an AS must be a contiguous collection of prefixes or it is not properly a single AS. Using the same ASN to represent multiple AS is a clear violation. > And they may use different carriers in different > cities.

Therefore, there is no reason to support such usage on a continuing basis. You violate the RFC's you takes your chances. Owen -- If it wasn't crypto-signed, it probably didn't come from me.
