Overview of IPv6 over Firewire: Multicast

• NDP messages are sent to L3 multicast

• Specification explicitly says that they must be sent via GASP.

• Other multicast should be negotiated via MCAP

• It uses L3 address
• IGMP layer tells drivers “L2 multicast address” only; not L3 address.
• 16 bytes does NOT fit into original 64bit-long “uniq_id” field.
