Hello everyone,
I configured Flexible Netflow on a Cisco ASR-920-4SZ-A, with IOS asr920-universalk9_npe.03.18.03.SP.156-2.SP3
The first exporter is working well but the second one is not working, no data sent.
If I remove the first exporter, it's working well. Netflow monitoring server is working well, it receives data from another interface.
Is there something wrong in my configuration ? Is it normal or a bug ? I read in the official doc it was possible to configure multiple exporters.

I would try to configure exporters with different configurations. For example, use different ports and source-interfaces (maybe loopback ones).
Give it a try.
