Yes, but just to be clear: The Flow Mobility ID defines FMI/FMA messages which use the same format as UPN with the new Code values. -Rajeev On Thu, Jun 19, 2014 at 6:46 AM, Sri Gundavelli (sgundave) < sgundave@cisco.com> wrote: > Hi Pierrick, > > After the NETEXT meeting in London, we had some offline discussions with > Rajiv and folks.
