Abstract Abstract
Bluetooth Smart is the brand name for the Bluetooth low energy Bluetooth Smart is the brand name for the Bluetooth low energy
feature in the Bluetooth specification defined by the Bluetooth feature in the Bluetooth specification defined by the Bluetooth
Special Interest Group. The standard Bluetooth radio has been widely Special Interest Group. The standard Bluetooth radio has been widely

do a multicast to all the connected 6LNs. If the 6LBR needs to send do a multicast to all the connected 6LNs. If the 6LBR needs to send
a multicast packet to all its 6LNs, it has to replicate the packet a multicast packet to all its 6LNs, it has to replicate the packet
and unicast it on each link. However, this may not be energy- and unicast it on each link. However, this may not be energy-
efficient and particular care must be taken if the master is battery- efficient and particular care must be taken if the master is battery-
powered. In the opposite direction, a 6LN always has to send packets powered. In the opposite direction, a 6LN always has to send packets
to or through 6LBR. Hence, when a 6LN needs to transmit an IPv6 to or through 6LBR. Hence, when a 6LN needs to transmit an IPv6
multicast packet, the 6LN will unicast the corresponding Bluetooth LE multicast packet, the 6LN will unicast the corresponding Bluetooth LE
packet to the 6LBR. The 6LBR will then forward the multicast packet packet to the 6LBR. The 6LBR will then forward the multicast packet
to other 6LNs. To avoid excess of unwanted multicast traffic being to other 6LNs. To avoid excess of unwanted multicast traffic being
sent to 6LNs, the 6LBR SHOULD implement MLD Snooping feature sent to 6LNs, the 6LBR can implement MLD Snooping feature [RFC4541].
