When Host A leaves the IPv6 multicast group, it sends an MLD done message to Switch A.
Receiving the message, Switch A removes port GigabitEthernet 1/0/4 from the member port list of
the forwarding entry for the group; however, it does not remove the group or forward the done
message to Router A because Host B is still in the group. Use the
display mld-snooping group
command to display information about MLD snooping groups. For example:
# Display information about MLD snooping groups on Switch A.
[SwitchA] display mld-snooping group
