Specifying the IGMP snooping version

Different versions of IGMP snooping process different versions of IGMP messages.
• IGMPv2 snooping processes IGMPv1 and IGMPv2 messages, but it floods IGMPv3 messages in
the VLAN instead of processing them.
IGMPv3 snooping processes IGMPv1, IGMPv2, and IGMPv3 messages.
•
If you change IGMPv3 snooping to IGMPv2 snooping, the device does the following:
Clears all IGMP snooping forwarding entries that are dynamically added.
•
Keeps static IGMPv3 snooping forwarding entries (*, G).
•
• Clears static IGMPv3 snooping forwarding entries (S, G), which will be restored when IGMP
snooping is switched back to IGMPv3 snooping.
