Mobile Internet Protocol

Mobile Internet Protocol (Mobile IP) enables the transfer of information to and from mobile computers, such as laptop and wireless communications. The mobile computer can change its location to a foreign network and still access and communicate with and through the mobile computer's home network. The Solaris implementation of Mobile IP supports only IPv4.

As of the Solaris 8 4/01 release, Mobile IP enables system administrators to set up reverse tunnels. A reverse tunnel can be set up from the mobile node's care-of address to the home agent. This reverse tunnel ensures a topologically correct source address for the IP data packet. By using reverse tunnels, system administrators can also assign private addresses to mobile nodes.

For more information on the Mobile Internet Protocol, see Chapter 22, Mobile IP Topics, in System Administration Guide: IP Services.
