MLD Snooping Querier Configuration Example
Network requirements
z As shown in Figure 9-6 , 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.
