Hi there,
Is there an easy way to update the source/destination AS numbers in
nfdump data? Has anybody done this already?
Background:
We have Cisco ASR 9000 with Trident linecards (1st generation; XFP
based). This generation of linecards does not support the export of
source and destination (and BGP next-hop) in IPv6 flows.
So I like to add the source and destination AS numbers based on an BGP
feed with the router. Right now I am thinking of setting up exabgp on
the NetFlow collector host. The exabgp would have a (multi-hop) BGP
session to the exporter and can update locally on the collector host the
nfdump data. But I'm totally unsure how to exactly accomplish the later.
Any guidance is appreciated.
Thanks,
Tim
