8.4.6 Example for configuring IGMP Snooping and IGMP Querier
Networking requirements
As shown in Figure 8-7, GE 1/1/1 on the switch is connected to the multicast router; GE 1/1/2
and GE 1/1/3 are connected to users. All multicast users belong to the same VLAN 10; you
need to configure IGMP Snooping on the switch to receive multicast data with the address
234.5.6.7.
Enable the IGMP Querier on the switch to reduce communication between the hosts and
multicast routers and implement the multicast function.
When the PC and set-top box are added to the same multicast group, the switch receives two
IGMP Report packets and only sends one of them to the multicast router. The IGMP Query
packet sent by the multicast router is not forwarded downstream, but the switch periodically
sends IGMP Query packets.
