What would you say? I dug a bit more and can suggest that RIPv2/Zebra sets IP_MULTICAST_LOOP flag. But then another question arises: is there a good way to detect such kind a traffic with Netfilter? I mean such a way that excludes a possibility for bogus traffic being treated as IP_MULTICAST_LOOP. -- End of message.
