hi Eric,
In 4.3.1 there is a feature that will allow you to do this.
The Border Gateway Protocol (BGP) dynamic route leaking feature provides the ability to import routes
between the default-vrf (Global VRF) and any other non-default VRF, to provide connectivity between a
global and a VPN host. The import process installs the Internet route in a VRF table or a VRF route in the
Internet table, providing connectivity.
You can follow the ASR9000 blog here to monitor when 4.3.1 will be posted to Cisco.com
