Thank you Pascal,

So I propose:
Note: Implementation also using another IID source MUST ensure that the same IID is shared between the device and the SCHC gateway.

Is it better ?

Hello Olivier




“

Note: Implementation also using another IID source MUST have same IID value on both device and SCHC gateway.
"

I agree with the intention. Now; this formulation could be read as “the GW and the device have the same IID” while you mean that “the GW and the device must obtain the same value as IID of the device”.
