For example, multicast is used by ND, the IPv6 equivalent of ARP. MLD
snooping means only a few hosts (typically only one, in fact) in the
subnet see any given ND request. Without MLD snooping, every port in the
subnet sees it. Or DHCPv6 - without MLD snooping, every port sees all
client traffic for all DHCP requests; with MLD snooping only the
routers/relays in the subnet see it. "See" with MLD snooping means "see
it at all", not "see and ignore it" as in the broadcast world.

Oh really? Exactly when during the ND process does a device send an MLD message that can be snooped?
