Ok, thank you for your clarification. I think I prefer Crossbow because it is a "modern" approach. Regarding threat model, I prefer to have as much separated traffic as possible, therefore I prefer exclusive-ip instead of shared ip. -- This message posted from opensolaris.org _

So you suspect there is no need to shut down the global NIC, if the zone uses exclusive IP and it is on a separate subnet and there is no routing between the zones? Ok, that is an interesting thought. What do you other people say? In that case a local zone can not ping (reach) the global zone?

Assuming you're using the shared IP stack (default), it is sufficient for the global zone interface(s) to be plumbed so that the non-global zones can use logical instances of the interface(s). So setting the GZ interfaces as "down' will prevent network access to/from the global zone. --Glenn
