IP tunnel administration in Oracle Solaris 11 has been revised to be consistent with the new model that is used for network datalink administration. In this release, you create and configure IP tunnels by using the dladm command. Tunnels can also use other datalink features that are supported in this release. For example, support for administratively chosen names enables you to assign tunnels more meaningful names than in previous releases. For more information, see the dladm(1M) man page.
