Hmmm strange - I do see v6 flows - although nfdump says their AS is 0 for all
flows. Exporting bgp attributes to the LC is enabled.

nfdump -o "fmt:%sa %sas" -R /var/cache/nfdump/2014/12/14/nfcapd.201412142350

I can validate this result  with

show flow monitor flowmon6 cache  location 0/1/CPU0

BGPSrcOrigAS is always 0
