GE2/0/3
GE2/0/5
As shown above, GigabitEthernet 2/0/3 and GigabitEthernet 2/0/5 on Switch C have become static
member ports for IPv6 multicast group FF1E::101.
MLD Snooping Querier Configuration Example
Network requirements
z
As shown in Figure 1-6 , in a Layer-2-only network environment, two multicast sources Source 1
and Source 2 send IPv6 multicast data to multicast groups FF1E::101 and FF1E::102 respectively,
Host A and Host C are receivers of multicast group FF1E::101, while Host B and Host D are
receivers of multicast group FF1E::102.
z
MLDv1 is enabled on all the receivers and MLDv1 Snooping is enabled on all the switches. Switch
A, which is close to the multicast sources, is chosen as the MLD snooping querier.
z
To prevent flooding of unknown multicast traffic within the VLAN, it is required to configure all the
switches to drop unknown multicast data packets.

Configuration procedure
1) Configure Switch A
# Enable IPv6 forwarding and enable MLD snooping globally.
<SwitchA> system-view
[SwitchA] ipv6
[SwitchA] mld-snooping
[SwitchA-mld-snooping] quit
# Create VLAN 100 and assign GigabitEthernet 2/0/1 through GigabitEthernet 2/0/3 to VLAN 100.
[SwitchA] vlan 100
[SwitchA-vlan100] port gigabitethernet 2/0/1 to gigabitethernet 2/0/3
# Enable MLD snooping and the function of dropping unknown IPv6 multicast data packets in VLAN
100.
