Hi Hesham,

I don't see a need for specifying GRE tunnelling in the current spec.

But I am at a loss to understand what Netlmm is expected to do to specify
GRE tunnelling for DSMIP6. It is best to simply say that the use of GRE
tunnelling in the context of DSMIP6 may be specified separately and leave it
at that.

I am fine with your proposed recommendation with the caveat that you do not
even mention which WG or document specifies the details of GRE tunnelling.
