IGMP snooping configuration
Notice that the ports connected to the source and the receivers are all in the same port-based
VLAN on the device. This is required for the PIM SM snooping feature. The devices on the edge of
the Global Ethernet cloud are configured for IP multicast traffic reduction and PIM SM traffic
snooping. Although this application uses multiple devices, the feature has the same requirements
and works the same way as it does on a single device.
IGMP snooping configuration
To configure IGMP snooping on FWS, FCX, and ICX devices, you need to perform the following global
and VLAN-specific tasks.
