[Roll] multicast & MLD on LLN

["Turner, Randy" <[e-mail]>]

I know there's a section on multicast in RFC 6550, which essentially states that the equivalent of a multicast "join" would be a DAO packet specifying multicast, rather than unicast addresses. It says that this method is not to be relied on in a non-storing network - however, I'm assuming we can still use this if we implement just a "lightweight storing mode", keeping track of only multicast addresses.  In this case a multicast "leave" would be when the DAO entry "times out"  - does this behavior obviate the need for MLD operation on this "quasi" storing mode LLN ?

Thanks!
Randy
