Hello. LW-IGMPv3/LW-MLDv2 is being publushed by mboned WG (draft-ietf-mboned-lightweight-igmpv3-mldv2) and consequently, IPv6 Node Requirements is being updated in the 6man WG (draft-ietf-6man-node-req-bis).
The node requirement says (in the section 5.7 in the -02 version): |5.7. Multicast Listener Discovery (MLD) for IPv6 - RFC 2710 | | | Nodes that need to join multicast groups MUST support MLDv1 | [RFC3590]. MLDv1 is needed by any node that is expected to receive | and process multicast traffic. Note that Neighbor Discovery (as used | on most link types -- see Section 5.2) depends on multicast and | requires that nodes join Solicited Node multicast addresses. | | Nodes that need to join multicast groups SHOULD implement MLDv2 | [RFC3810]. However, if the node has applications that only need | support for Any-Source Multicast [RFC3569], the node MAY implement | MLDv1 [RFC2710] instead. If the node has applications that need | support for Source-Specific Multicast [RFC3569], [RFC4607], the node | MUST support MLDv2 [RFC3810]. In all cases, nodes are strongly | encouraged to implement MLDv2 rather than MLDv1, as the presence of a | single MLDv1 participant on a link requires that all other nodes on | the link operate in version 1 compatability mode. | | When MLDv1 is used, the rules in the Source Address Selection for the | Multicast Listener Discovery (MLD) Protocol [RFC3590] MUST be | followed. IMHO, we WG might want to update this text after LW-IGMPv3/MLDv2 has been publushed. Otherwise, all nodes that has applications need SSM MUST implement "full" MLDv2 (RFC3569, RFC4607) anyway, instead of LW-MLDv2; MLDv2 is not only for the wire format but also for state processing.
