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, while Host B and Host D are receivers of multicast group
225.1.1.1. IGMPv2 runs on all the receiver hosts. IGMPv2 snooping runs on Device A, Device B, and
Device C. Device A serves as the IGMP-snooping querier.
To prevent flooding of unknown multicast traffic within the VLAN, configure all the devices to drop
unknown multicast data packets. Configure a non-all-zero IP address as the source IP address of IGMP
queries to ensure normal creation of multicast forwarding entries.
