IGMP snooping querier configuration example

Network requirements
As shown in
•
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, and Host B and Host D are receivers of
multicast group 225.1.1.1.
All the receivers are running IGMPv2, and all the switches need to run IGMPv2 snooping. Switch
•
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, configure all the switches to drop
•
unknown multicast data packets.
Because a switch does not enlist a port that has heard an IGMP query with the default source IP
•
address of 0.0.0.0 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.
