Hi,

Regarding the mic discussion about unicast RAs a SHOULD.

I have been directed that the reference saying that Hosts dont MLD to 
join multicast groups is RFC3810:

"  The link-scope all-nodes multicast address, (FF02::1), is handled as
    a special case.  On all nodes -- that is all hosts and routers,
    including multicast routers -- listening to packets destined to the
    all-nodes multicast address, from all sources, is permanently enabled
    on all interfaces on which multicast listening is supported.  No MLD
    messages are ever sent regarding neither the link-scope all-nodes
    multicast address, nor any multicast address of scope 0 (reserved) or
    1 (node-local)."
