No I'm not suggesting basing it on what a provider is currently advertising. But rather on what the provider has registered and is authorized to announce. The set of authorized routes may be the same or a superset of what the routes the provider is currently announcing. If you want asymetric routes, you can register and authorize traffic via either route; and then dynamically announce which route you want to use moment to moment.
