Mld Snooping Querier Configuration Example - H3C S3100 Series Operation Manual

As shown above, Ethernet 1/0/3 and Ethernet 1/0/5 on Switch C have become static member ports for
IPv6 multicast group FF1E::101.

MLD Snooping Querier Configuration Example

Network requirements
As shown in
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.
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.
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 Ethernet 1/0/1 through Ethernet 1/0/3 to VLAN 100.
[SwitchA] vlan 100
[SwitchA-vlan100] port ethernet 1/0/1 to ethernet 1/0/3
# Enable MLD snooping and the function of dropping unknown IPv6 multicast data packets in VLAN
100.
[SwitchA-vlan100] mld-snooping enable
[SwitchA-vlan100] mld-snooping drop-unknown
# Configure MLD snooping querier feature in VLAN 100.
