Hey Kamlesh,
   I'm not sure that I see any particularly complex issue with
regard to MPLS flow/tag reporting.  There don't seem to be 
any unique issues that MPLS presents that don't have to be addressed
to support, say, extending the 5-tuple flow model to include the
ifIndex as a key to the flow, or to report the ifIndex as an
attribute of the traditional 5-tuple flow.

Carter,

Good point. It is this "little bit of attention to the flow key and
data" in the context of MPLS is what we were talking about. 

But you present a good way to look at it, and deal with it along with
the list of other flow types.

Regards.
