NDE export using a VRF interface

[linker.team]

Is it possible to use the vrf interface as source of netflow packets? if so how to configure ip flow-export source <vrf interface?

You can collect statistics for both routed and bridged traffic. Note, however, that the PFC3A collects statistics only for routed traffic. You can configure two external data collector addresses, which improves the probability of receiving complete NetFlow data by providing redundant data streams with a PFC3.

To reduce the volume of statistics collected, use:

Sampled NetFlow, which reduces the number of statistics collected

NetFlow aggregation, which merges collected statistics

Hello,

you can use the following syntax:

Router(config)# ip flow-export destination 10.10.10.10 2000 vrf testvrf

Router(config-flow-cache)#export destination 10.10.10.10 9999 vrf testvrf

NetFlow VRF export is introduced in 12.4(4)T on the low-end routers.

Kind regards
