Solaris 10 8/07: The IP instances project enables you to configure a zone as an exclusive-IP zone and assign exclusive access of some LANs or VLANs to that zone.
The previous behavior of shared-IP zones remains the default behavior. The exclusive-IP zone means that all aspects of the TCP/IP state and policy are per exclusive-IP zone, including TCP/IP tunable parameters.
The introduction of the IP instances feature means that the following TCP parameters can only be set in the global zone because they require the PRIV_SYS_NET_CONFIG privilege:
The other TCP, IP, and SCTP parameters and route metrics only require the PRIV_SYS_IP_CONFIG privilege. Each exclusive-IP zone controls its own set of these parameters. For shared-IP zones, TCP, IP, SCTP, and route parameters are controlled by the global zone since the settings of these parameters are shared between the global zone and all shared IP zones.
For more information about using IP instances in Solaris zones, see System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones.
