Exclusive-IP Zone Partitioning

Exclusive-IP zones have separate TCP/IP stacks, so the separation reaches down to the data-link layer. One or more data-link names, which can be a NIC or a VLAN on a NIC, are assigned to an exclusive-IP zone by the global administrator. The zone administrator can configure IP on those data-links with the same flexibility and options as in the global zone.
