So far, we have mainly discussed the need for an optimization (it seems we now agree there is a need) and the interaction between the normative components of RFC 6437 and those of the draft at hand.

I’d now like to bring up a different question:

Is this the right approach?

I have written up what appears to be a more natural approach in the strawman draft:
http://tools.ietf.org/html/draft-bormann-6lo-rpl-mesh-00

Why are we doing the flow-label thing and not the more natural thing?

[ ] because the flow label hack works on packets that leave the 6lo networks.
    • but do we really need to optimize this on the non-6lo networks?
[ ] because the flow label hack has been around for a while and is now cast in stone.
    • is it?
[ ] because there is a flaw with the way this has been integrated into the 6lo framework.
    • ______ (fill in the flaw)
[ ] because ______ (fill in the reason)

Inquiring minds want to know.

Grüße, Carsten
