Fact checking IPv6: on a switch without MLD snooping, all ICMPv6 multicast packets (neighbor discovery, router discovery/advertisements and so on) are sent to all ports of the switch; they are thus visible in promiscuous mode by all nodes connected to the switch. And that means that multicast in this case is not more efficient than broadcasts from the network load point of view. Or am I missing something ?

Introductory post: this is my public sub-account for #IPv6 content; my main account is linked in my profile.
I support the complete roll-out of IPv6, including intermediate efforts like dual-stack support and #NAT64 #DNS64 #CLAT, with the ultimate goal of native IPv6 support in all-new deployments, using RFC standards and best practices.
I support subnets no smaller than /64 (#SLAAC), ISPs should delegate prefixes of at least /56 or /48, and #ICMPv6 should be rate-limited, never blocked.
