ASN Flow Exporter for OpenBGP device
Hello, I have an OpenBGP device and I need to find out which ASN demands more bandwidth to do some sort of traffic policy engineering. Therefore I need to know if there is any software that is able to export netflow data including SRC/DST AS on an OpenBGP system. I have used pfflow and softflowd but on the second AS is always '0' and pfflow will depend on the ability to have pf data per ASN. I know I can set up some rtlabel or pftable to allow OBGP interaction with PF. However, I would need to manually set the whole scenario and the reliability of my information would depend on my observation of potential ASN to be tracked. Its OK but this way I miss the behavior deviations, if a certain quiet ASN suddenly raises traffic and later lowers it back again. So, how options we have? Thank you in advance. -- === Eduardo Meyer pessoal: dudu.me...@gmail.com profissional: ddm.farmac...@saude.gov.br

One approach would be auto labeling routing entries by AS (basic support for it already exists) and later, pflow would check for it on exporting time, or maybe check from openbgp directly. I hope its possible somehow. Thank you for your time, we really appreciate. -- Henning Brauer, h...@bsws.de, henn...@openbsd.org BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting -- === Eduardo Meyer pessoal: dudu.me...@gmail.com profissional: ddm.farmac...@saude.gov.br

Therefore I need to know if there is any software that is able to export netflow data including SRC/DST AS on an OpenBGP system. take a look at pmacct, it's in ports/packages. it can collect netflow data and peer bgp (quagga-based code) to add ASN information, but as far as I know the bgp code hasn't been tested on OpenBSD yet.
