Configuring Layer 2 Multicast IGMP Snooping Configuration
The following example shows how to enable IGMP Snooping and header validation globally,
and specify the IGMP Snooping version as IGMPv3, the way how the switch processes
multicast streams that are sent to unknown multicast groups as discard.
Switch#configure
Switch(config)#ip igmp snooping
Switch(config)#ip igmp snooping version v3
Switch(config)#ipv6 mld snooping
Switch(config)#ip igmp snooping drop-unknown
Switch(config)#ip igmp snooping header-validation
Switch(config)#show ip igmp snooping
IGMP Snooping :Enable
IGMP Version :V3
Unknown Multicast :Discard
Header Validation :Enable
...
Switch(config)#end
Switch#copy running-config startup-config
2.2.2 Configuring IGMP Snooping for VLANs
Before configuring IGMP Snooping for VLANs, set up the VLANs that the router ports and
the member ports are in. For details, please refer to Configuring 802.1Q VLAN.

Snooping is enabled globally, you also need to enable IGMP Snooping and configure the
corresponding parameters for the VLANs that the router ports and the member ports are
in.
