I said *the nodes* at both ends need to be modified to support the flow 
label scheme. The flow label does not necessarily need to get modified 
at both ends.
[If these ends mean the two ends of softwire, then it is fine. But from your
previous emails I thought you meant the ends refer to the two ends of the
point-to-point tunnels. If it means the two ends of PPPoE, it is not
correct, because there is no IPv6 packet at that time.
Would you clarify a little bit? Thank you.]

Thanks
Suresh
