Any internet service providers out there interested in MPLS NetFlow reports for network traffic analysis? I was reading this document on NetFlow MPLS Label Export and thought it might be interesting data to report on.

For those of you not familiar with this topic, 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 <<taken from the Cisco document>>.

The MPLS PAL packets are exported as NetFlow options packets rather than NetFlow data packets. NetFlow options packets are defined in Cisco Systems NetFlow Services Export Version 9, Request for Comments (RFC) 3954.

Scrutinizer already supports “option templates”, but more work would have to be done to support the above. If you are interested in this information, what types of reports are you looking for?

  • VRF to PE and PE to VRF matrix
  • PE to PE matrix
  • VRF-to-VRF traffic matrix (may not be supported)

Contact me directly if you are interested in gaining the above information. We can help you with the NetFlow Analysis.

Michael is one of the Co-founders and the former product manager for Scrutinizer. He enjoys many outdoor winter sports and often takes videos when he is snowmobiling, ice fishing or sledding with his kids. Cold weather and lots of snow make the best winters as far as he is concerned. Prior to starting Somix and Plixer, Mike worked in technical support at Cabletron Systems, acquired his Novell CNE and then moved to the training department for a few years. While in training he finished his Masters in Computer Information Systems from Southern New Hampshire University and then left technical training to pursue a new skill set in Professional Services. In 1998 he left the 'Tron' to start Somix which later became Plixer.
