Hi

Sorry for late answer. It is not supported currently, but you can do that with attached unofficial patch. The patch will cause to use existing MPLS next-hop label stack even if IP next hop is reset to local address during BGP export. So you can define static route with MPLS stack and announce it. Perhaps you would also need to add static MPLS rules to decapsulate incoming labeled traffic.
