= Yes to both questions I think. If we didn't point to MLDv1 then the change woulod not be backward compatible. I.e. using MLDv2 only would break old implementations. As for the second question, I agree that it makes MLDv2 normative but I was hoping the or would get us out of

But, I was shouted down, so I don't oppose it either. Perhaps, but this also makes it sound like there were now compelling reasons to oppose the change. Fact is, the IPv6 WG made the decision a long time ago (10+ years?) that even if snooping bridges are an abomination (and many people think

Meanwhile. If I remember correctly, this sentence was added due to a claim from someone who argued it is not clear that joining a multicast group normally involves MLD (whether it's v1 or v2) operations. Perhaps it was me? I opposed the need to use MLD (of any kind) for

Just as a general intuition, I'm concerned that the IPv6 suite is becoming less careful over time about the use of soft state inferred from snooping various protocol interactions. IMHO, inferring soft state is OK, as long as that state is an optimization and not a requirement for system
