Important Points to Remember for IGMP Snooping
● The Dell Networking OS supports version 1, version 2, and version 3 hosts.
● The IGMP snooping implementation is based on IP multicast address (not based on Layer 2 multicast mac address) and the
IGMP snooping entries are in Layer 3 flow table not in Layer 2 forwarding information base (FIB).
