You can configure an export routing policy when a finer control on the VPN instance routes to be 

redistributed is required, that is, when the control provided by the extended community attribute is not 

enough. An export routing policy may deny routes that are permitted by the export target attribute.  

By default, all VPN instance routes permitted by the export target attribute can be redistributed.
