Symptom
Netflow does not count the amount of traffic correctly.
There is a running flow which sends IP packets with a len of 78. These IP packets are encapsulated in MPLS VPN (2 labels added).
The netflow cache raises a packet len of 100 bytes per packet which is not aligned with my packet length.
It seems that the ASR1k counts the layer 2 MAC header in addition to the IP+MPLS headers while in the configuration not used the "layer2" keyword in the recording template.
Conditions
MPLS LSR and NetFlow configured on ASR1K. IP packets are encapsulated in MPLS VPN (2 labels added).
