What about multicast

[hervé]

Hi all,

On my PC I send an UDP broadcast to find all board connected to the network.
Each board reply with its own IP address (and some other information).
It works fine on a local network; but I had to do the same on a more complex network with routers, so I plan to replace the UDP Broadcast with a UDP Multicast Broadcast.
Does anybody has information on how to configure my board to accept this multicast and join the multicast group ?

Thanks
