# Create VLAN 100, assign Ten-GigabitEthernet 1/1/5 through Ten-GigabitEthernet 1/1/8 to
the VLAN, and enable MLD snooping and the function of dropping IPv6 unknown multicast data
for the VLAN.

Verifying the configuration
Assume that Host A and Host B want to join the IPv6 multicast groups FF1E::101 and FF1E::202 to
receive the IPv6 multicast data from the IPv6 multicast source.
# Display information about the dynamic MLD snooping forwarding entries in VLAN 100 on Switch A.
[SwitchA] display mld-snooping group vlan 100
Total 1 entries.
VLAN 100: Total 1 entries.
(::, FF1E::101)
Host slots (0 in total):
Host ports (2 in total):
XGE1/1/7
XGE1/1/8
The output shows that Host A and Host B have joined the IPv6 multicast group FF1E::101 (through the
member ports Ten-GigabitEthernet 1/1/8 and Ten-GigabitEthernet 1/1/7 on Switch A, respectively),
but the hosts have failed to join the multicast group FF1E::202.
