• FTOS 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 FIB.
• FTOS IGMP snooping implementation is based on draft-ietf-magma-snoop-10.
• FTOS supports IGMP snooping on JUMBO enabled cards.
