Hello, I'm Henning Rogge, one of the programmers of the OLSR.org routing daemon. OLSR is a proactive mesh net protocoll and our implementation is used mostly on small routers or embedded hardware. At the moment OLSR.org does only support unicast routing (by setting routes in the linux kernel to do the hop-by-hop forwarding), but we would like to add the ability to use multicast too. OLSR is a proactive routing protocol, so each routing daemon has information about the whole network topology. Most mesh networks use wireless links, so we don't have well defined broadcast interfaces and often have to retransmit incoming packages back through the same interface. Does the linux kernel support setting up multicast forwarding rules like this so we could create multicast trees by the routing daemon and let the kernel forward the packages (and drop duplicates) ?
