I am a bit puzzled. The vague referemce to a limited domain has gone, which is fine. But the only thing that relates to that issue is a statement in the Security Considerations that:

"... nodes MUST discard packets containing the CRH when both of the following conditions are true:

The Source Address does not identify an interface on a trusted node.

The Destination Address identifies an interface on the local node."

The term "trusted node" is not defined; in fact there is no discussion whatever of the trust model and how trust is established (and how forged source addresses are avoided). I think the chances of this draft surviving a Security Area review are very small.
