In all cases (use of import target or more global route-target) is correctly handled by contrail-control. I can see the correct targets from introspect page under bgp_peer > ShowRoutingInstanceSummaryReq.
But the fact is when I use Import Route Target the corresponding prefix is not imported into the VN. If I use the more global Route target option, the prefix is correctly added.
