Upgrading the Virtual I/O Server from IPv4 to IPv6

To take advantage of enhancements, such as expanded addressing and routing simplification, use the mktcpip command to upgrade the Virtual I/O Server from Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6).

IPv6 is the next generation of Internet protocol and is gradually replacing the current Internet standard, Internet Protocol version 4 (IPv4). The key IPv6 enhancement is the expansion of the IP address space from 32 bits to 128 bits, providing virtually unlimited, unique IP addresses. IPv6 provides several advantages over IPv4 including expanded routing and addressing, routing simplification, header format simplification, improved traffic control, autoconfiguration, and security.
Run the following command to upgrade from the Virtual I/O Server from IPv4 to IPv6:
mktcpip –auto [-interface interface]
where interface specifies which interface you want to configure for IPv6.

This command automatically performs the following tasks:

If you decide that you want to undo the IPv6 configuration, you must completely remove the TCP/IP interface and then configure a new TCP/IP interface for IPv4. For instructions, see Changing the network configuration of the Virtual I/O Server logical partition.
