This is not a good solution for most of the broadcast packets that he mentioned, EIGRP Hellos, DHCP, and ARP. Those represent perfectly normal traffic that must not be supressed if you want the network to work! :-) He also mentioned the Symantec Ghost disk imaging software that is sending to 224.77.x.x. For now, he implemented a VLAN to segregate this traffic. I do hear a lot of complains about this Ghost. Does it really need to send multicasts? Does anyone have any ideas how to make it less of a bad network citizen? Do you use a VLAN? I think this is where we need to concentrate to help the original poster. Gotta run. Please comment if you can, folks. It would be very helpful. THANKS.
