Hi,
I'm in the process of configuring FnF on an ASR1000 and have run into an issue. I'm wondering if anyone else has experienced an issue where the source IP address displayed doesn't match the IP address of the source interface. I've configured Loopback0 as the source but when I do a "show flow exporter" it always displays the IP address of the Loopback1 interface. In fact, it doesn't matter what source interface I use, the source IP address displayed is always from my L1 interface.
I have not performed a capture yet to see if this is just cosmetic or if netflow traffic is actually sourced from L1.
