I don't use the Netflow Collector software. But the way netflow
AS aggregation works, the IP addresses for each flow are looked up
in the local forwarding table to find the associated ASN. If you
don't have a route to the source or destination of that flow, it
will register as AS = 0. AS aggregation produces the most useful
results in routers carrying full routing tables. To the extent
that you're using a default route, you'll see lots of "other" traffic.
