Hi Gabriel and 6lowpaners,
I want to raise an issue of supporting IPv6-multicast in 6lowpan.
There are some cases which might require multicasting in 6lowpan such as packet transmission with multicast targets (0xFF~), Neighbor or Router advertisements.
We can optimize some multicast by using an optimization technique, e.g. ND optimization, but not for all cases such as multicast targets(0xFF).
Because the link layer of 6lowpan does not support multicast, multicast should be realized by broadcast (or flooding).
My question is whether the current format document does support the broadcasting(or flooding) or not.
It is clear that broadcast ID should exist on the adaptation layer for supporting broadcasting(or flooding) at the adaptation layer. ( in order to avoid duplicate handling of the same broadcast messages on a node)
Is there a mechanism of broadcast ID in the current format document? If the adaptation layer does not have the mechanism, I believe that we should include it.
What is your opinions?
