Thank you for suggestion. But I'm afraid I didn't understand you clearly.

telnet at lsr1-gdr.ki#show ip bgp vpnv4 route 173.194.40.0/24
BGP Routing Table is empty

I don't need any VPN. I have a single box with two BGP neighbors connected to,
each neighbor in separate VRF.
In one VRF I need to import routes from different VRF and announce them to BGP
neighbor. But I cannot do that because BGP attributes is lost during import.
