=> both reasons. In the same kind of design ideas, it is
forbidden to mix unicast and multicast between layers, i.e.,
if the IPv6 destination is unicast, the link-layer destination
MUST be unicast, and same with multicast in place of unicast.
Can you point me to the text that forbids this? I was under the impression that multicast emulation mechanisms (e.g. MARS, etc.) use unicast link-layer destination addresses when the IPv6 destination is multicast. The whole point of multicast emulation is to propagate network-layer multicasts over unicast-only link layers - not true?
