So, I tried tracing again and you all were correct.  There was a BGP group on edge01 with the cluster-id of, which was causing the route to drop.  I believe my problem with tracing was that I was not tracing the right information and using a prefix filter under the 'route' flag.

Thanks to all who responded.  I now know that routes with cluster-id issues will be dropped with no addition to the RIB.
