Perhaps the only question that I have left is... whether IPv6 nodes should support MLDv2 instead of MLDv1. The node requirements document and the MLDv2 draft intro gives the impression that the only difference is source-specific filtering. Then the current node reqs rules make sense. But Appendix B of the MLDv2 draft seems to list a number of other modifications, including some enhancements to robustness. Are these important? I'm not an expert enough to determine that.
Appendicies are non-normative, so I think that we don't need to
worry about it in the Node Requirements document, though I am by no means an MLD expert.
Appendix B of the MLDv2 draft is simply a list of changes from MLDv1. While this list is non-normative, I think the changes are in the body... so my question is whether there's really a bit more to MLDv2 than source-specific multicast. But lets stop the discussion between MLD non-experts and ask someone who knows: Brian, are there other improvements in MLDv2 than source-specific multicast? If yes, are those significant enough that nodes should migrate to MLDv2 even if they don't use the source-specific multicast feature?
