As kre points out I think the draft answers your questions, but I want to followup on one point that should probably be clarified in the draft. When you say "currently unreachable (no entry in neighbor cache)" it sounds like you might have a misunderstanding. If the host has no information about the router's reachability then the host should assume the router is reachable.
