MLD Snooping Querier Commands
In an IPv6 environment, MLD Snooping requires that one central switch or router periodically
query all end-devices on the network to announce their multicast memberships. This central
device is the MLD Querier. The MLD query responses, known as MLD reports, keep the
switch updated with the current multicast group membership on a port-by-port basis. If the
switch does not receive updated membership information in a timely fashion, it will stop
forwarding multicasts to the port where the end device is located.
