[c-nsp] Netflow + MPLS issue on PE routers

[Anrey Teslenko]

Hello!

We are exporting netlfow statistic from our PE routers (C7600).

We use flow export v5. Netflow collector is Flow-capture.
We observed that  statistic which we exported are not correct.
Too small amounts of traffic in statistic compared to the actual value

PHP is disabled on PE routers (for some reason) so packages have MPLS header.
We think this is main cause why  we didn't receive properly statistics.
But PHP must be disabled for us.

My question is:
What should we do to recive a correct statistic?
Could we enable only flow export v9 to fix that?
or maybe
Could we enable only "ip flow egress" per downlink interfaces? If this
possible  for 7600.

What are you think about "MPLS-aware NetFlow"? Could it to help us?

Thanks in advance.
