What are the guidelines for using unicast and multicast with Ghost?
Unicast is best when taking an image or when restoring an image to up to 5 computers at a time. If you have routers or switches that are not configured for multicast, use unicast. In some cases you may be able to ghost across a WAN, but it is not recommended. Check the document 'Can Ghost be used across a Wide Area Network ( WAN ) ?' at http://www.symantec.com/docs/TECH109652
NOTE: Typically, when configuring multicasting on routers and switches, include configuration for IGMP. See the document 'Ghost compatibility with IGMP' at http://www.symantec.com/docs/TECH107126
NOTE: Regardless of which type of communication you choose, a network can get flooded when Ghost is left unthrottled. Check the document 'Throttling Symantec Ghost to reduce the load on the network' at http://www.symantec.com/docs/TECH110645
