1.2 Supported Layer 2 Multicast Protocols



Layer 2 Multicast protocol for IPv4: IGMP Snooping

On the Layer 2 device, IGMP Snooping transmits data on demand on data link layer by

analyzing IGMP packets between Layer 3 devices and users, to build and maintain Layer 2

multicast forwarding table.



Layer 2 Multicast protocol for IPv6: MLD Snooping

On the Layer 2 device, MLD Snooping (Multicast Listener Discovery Snooping) transmits

data on demand on data link layer by analyzing IGMP packets between Layer 3 devices and

users, to build and maintain Layer 2 multicast forwarding table.
