Hi Baptiste,
are you sending from your Linux host or your border router? Because
`ff02::1` is link-local and should not be forwarded by a border router. Try
set-up a multicast address with a broader scope than link-local at your
nodes, e.g.

ifconfig 7 add ff04::1

And try if that works.

Cheers,
Martine
