Hi! We are testing pmacctd (or more specifically nfacctd) to collect netflow data from a Quagga router. To export the flows we are using ipt-netflow which seem to be working nicely. We did however run in to some issues when trying to set up the BGP daemon of nfacctd to also collect src/dst AS and AS paths.
The BGP session opens as expected and nfacctd is receiving UPDATEs until suddenly it reports that it "Received malformed BGP packet (marker check failed)". After this, the BGP session keeps flapping between Idle and Established and no new UPDATEs are received. Has anyone seen this issue or have any idea what we might be missing? I'm posting the BGP parts of our nfacctd configuration at the bottom as well as the Quagga configuration. Thanks!
