A township board extends briefing channels to IPv6 endpoints on the LAN edge. Which protocol fills the receiver-signaling role that IGMP provides for IPv4?
Select an answer to reveal the explanation.
Short Explanation
IPv6 still needs a way for desktops to say “tune me into this group.” That job belongs to MLD—same idea as IGMP, different address family. Neighbor Discovery and DHCP do other chores; they are not the membership protocol.
Full Explanation
Multicast Listener Discovery (MLD), carried in ICMPv6, is the IPv6 host-to-router protocol for reporting multicast listener state, analogous to IGMP in IPv4. MLDv1 roughly parallels IGMPv2; MLDv2 adds source filtering similar to IGMPv3. Neighbor Discovery and DHCPv6 do not replace MLD for group membership signaling on the LAN edge.
