I do not think that Cf currently handles multicast addresses correctly. There have been some issues around this on GitHub [1].
There does not seem to be much interest in the community to work on it and fix it at the moment :-(

Subject: [cf-dev] Multicast ipv6 Address
Dear all,
I am wondering whether Californium supports multicast ipv6 address. The reason why I am asking is because we tried to use Coap to send message to a coap server through FF02::1, which should be able to multicast to all nodes in the network. It works with
a simple example of MulticastSocket in Java but It does not work in Californium. Am I missing something important here?
Karlson
