That's assuming there was no link-local communication, but just packets being send/received to the external network? > Totally random crazy idea: could there be firewalls on some of these > machines that are causing multicast RAs to be filtered but unicast RAs > are fine (e.g. a unicast RA reply to an RS)? Not sure if "firewalls", but I could think of swtiches that fail to do MLD snoping and hence do not forward multicasted packets?
