Hi All,

We have a bit challenges with respect to doing the code changes in OF plugin to support the new IPv6 attributes [0] as a mandatory for complete this feature(OVS_NA_RESPONDER) from ODL controller side. These new attributes are not comes under the NXM or OXMs standards. So, to add new extension standards in OF plugin also not feasible at this point of time due to IPR clearance of the proprietary code changes.

we can add this feature support once OVS side changes are ready. Till that point we can put this feature on hold.

We can not able to deliver this feature in fluorine release.

 

Thanks,

Karthikeyan.
