First, remember that load balancing is not a design principle of BGP.
There is no simple, automatic way to get load sharing among multiple
AS. One approach is to take full routes from each, making the
assumption that each AS will be the best path for an approximately
equal number of destination AS. Beyond that, you must get into
significant policy and traffic analysis, but you simply will not be
able to load share to the extent you can in enterprise IGPs.
