Origin AS is easily handled by the allow-as-in neighbor command and
better replaced with more flexible as-path and prefix-lists in route-maps.
The interconnection is required to be able to advertise the entire space
as a "covering" prefix at both sites.
Doing that without interconnectivity and using your static route idea
would generate routing loops.
