Best practices for unicast and multicast with Ghost
Last Updated February 22, 2017
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
For more than 5 computers at a time, use multicasting or directed broadcast. Routers and switches typically are not pre-configured for use with multicast.
Directed broadcast is basically multicasting to a particular subnet.
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
