In this Oracle Solaris release, tunnel administration is separated from IP interface configuration. You administer the datalink aspect of IP tunnels with the dladm command and the IP aspect of configuration (including those for IP tunnels) by using the ipadm command.
The following dladm subcommands are used to configure IP tunnels:
create-iptun
modify-iptun
show-iptun
delete-iptun
set-linkprop
For more information, see the dladm(1M) man page.
IP tunnel administration is closely associated with IPsec configuration. For example, IPsec virtual private networks (VPNs) are one of the primary uses of IP tunneling. For more information about network security in Oracle Solaris, see Chapter 8, About IP Security Architecture in Securing the Network in Oracle Solaris 11.3. To configure IPsec, see Chapter 9, Configuring IPsec in Securing the Network in Oracle Solaris 11.3.
