Juarez,

Why do ipfix implementations such as vermont, maji, YAF(silk) just
export ipfix messages and not netflow v9 messages?

[...]

Is there some legal restrictions with cisco?


No. While Cisco holds patents pertaining to NFv9 export, we allow that:

  "If any claims of any issued Cisco patents are necessary for
   implementing this specification, any party will have the right to use
   any such patent claims under reasonable, non-discriminatory terms,
   with reciprocity, to implement and fully comply with the
   specification."


IPR for RFC 3954 can be found here:

Cheers,
P.
