Well ..... I know google too, and I know this link . Thx for the answer .
My problem is that the beagle still receive the multicast packet (yes it ignore all multicast packet), which is a problem for me when you are in a network full of camera That love to send multicast packet ! I tried to disable multicast in the kernel, but it still receive multicast packet. Do you know a solution to prevent this ?
