I don't think that is the issue. Linux ClusterIP is most likely not using Ethernet Multicast packets in the same range that is reserved for IP Multicast (01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff), so IGMP and PIM would have nothing to do with it at all. The issue is that ClusterIP is playing fast and loose with the standards, so standards-based networking devices don't work with it. This is similar to how Microsoft Network Load Balancing (NLB) works. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
