The NetFlow MPLS Label Export feature allows a label switch router (LSR) to collect and export 
Multiprotocol Label Switching (MPLS) labels allocated by the LSR when an adjacent router pushes that 
label on the top of the label stack of a transit packet. At the same time, the LSR collects the prefix 
associated with the MPLS label and the application that allocated the label. The router collects the 
information in a table called the MPLS Prefix/Application/Label (PAL) table and exports this data to a 
NetFlow collector as the label is allocated or, if so configured, periodically exports the full MPLS PAL 
table. 

You can use this information to create a provider edge (PE)-to-PE matrix, which is useful for network 
traffic planning and billing. To realize this benefit, you must export the MPLS label information to a 
NetFlow collector for analysis. This feature also provides information that a NetFlow collector can use 
to create a Virtual Private Network (VPN) routing and forwarding instance (VRF)-to-PE and PE-to-VRF 
matrix.

Your Cisco IOS software release may not support all of the features documented in this module. To reach
