become static member ports for multicast group 224.1.1.1.
IGMP snooping querier configuration example
Network requirements
As shown in Figure 16, in a Layer 2–only network environment, two multicast sources Source 1 and
Source 2 send multicast data to multicast groups 224.1.1.1 and 225.1.1.1, respectively. Host A and Host C
are receivers of multicast group 224.1.1.1. Host B and Host D are receivers of multicast group 225.1.1.1.
IGMPv2 runs on all the receivers, and IGMPv2 snooping runs on all the routers. Router A, which is close
to the multicast sources, is chosen as the IGMP snooping querier.
To prevent flooding of unknown multicast traffic within the VLAN, be sure to configure all the routers to
drop unknown multicast data packets.
Because the SAP module does not enlist a port that has heard an IGMP query with a source IP address
of 0.0.0.0 (default) as a dynamic router port, configure a non-all-zero IP address as the source IP address
of IGMP queries to ensure normal creation of Layer 2 multicast forwarding entries.
