Is it possible to use the vrf interface as source of netflow packets?

NetFlow VRF Export:
- Allow the export of flow records within a VRF.
- Valid for both SCTP* and UDP export.

Router(config)# ip flow-export destination 10.1.1.2 2000 vrf testvrf <sctp|udp>
Router(config-flow-cache)# export destination 10.1.1.2 2000 vrf testvrf <sctp|udp>

where testvrf is a VRF name.

Introduced in 12.4(4)T on the low-end routers.

* SCTP is not supported by Caligare Flow Inspector at this time.
