The internet traffic is in VRF but at customer side not my side. We have only eBGP between me and customer. The customer preferred to modify the local preference at his PE routers to select the defult routes. Thanks for your help.

Best Regards,

Yes, The customer are putting all internet traffic in VRF.

Should be pretty easy then, if the internet traffic is already in a VRF, you should be able to accomplish your goals by simply using route-target-import and route-target-export commands to dynamically leak prefixes into the appropriate VRFs.  If your particular source subnets are already constrained to a particular VRF (via interface to VRF binding) you won't even need to do the Filter-Based-Forwarding stuff as they will already be constrained to a particular routing-instance.
