Make sure that your two location is inter-connected directly,
Why is this required? If you put static routes to point the remote /21 to the upstream provider on each side wouldn't that take care of the origin AS loop?
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.
