As an initial step to use IPv6 addressing on a network, you must configure IPv6 on the system's IP interface. During the installation process, you can enable IPv6 on one or more of a system's interfaces.
If you enable IPv6 support during installation, then after the installation has completed, the following IPv6-related files and tables are in place:
The name-service/switch SMF service is modified to accommodate lookups using IPv6 addresses.
The IPv6 address selection policy table is created. This table prioritizes the IP address format to use for transmissions over an IPv6-enabled interface.
