Explanation/Reference: Explanation: MPLS-aware NetFlow uses the NetFlow Version 9 export format. If you are exporting MPLS data to a NetFlow collector or a data analyzer, the collector must support NetFlow Version 9 flow export format, and you must configure NetFlow export in Version 9 format on the router.
