how to make the HWMP able to support multicast communications

[Konstantinos]

Hi,

This is not something of-the-self. You would have to create the appropriate callback for multicast forwarding on Layer-2 (that does not exist) and other methods to identify a multicast route.

Currently you can find the ns3::MeshL2RoutingProtocol::RouteReplyCallback  which is called when a packet is to be forwarded. But this is for unicast.

If you want to do multicast, you should create a similar callback and wire it properly.

This callback is fired in ForwardUnicast() method of HWMP. In a similar way, you could do for multicast. I would recommend looking at IP routing and RouteInput method which is similar to this one.
