Although TCP/IP initializes in dual mode, the IPv6 address autoconfiguration feature defaults to disabled to prevent automatic IPv6 operation. The IPv6 networking stacks and appropriate data structures are initialized for a particular interface when either
-
The network administrator manually (statically) configures an IPv6 address on the interface using the TCPIP ROUTE command. See Configuring Multiple Routes to a Remote Destination for details on using this command.
-
Address autoconfiguration is enabled for the interface and network connectivity is available. See Assigning IP Addresses to a Network Interface for details on using the TCPIP [TCPIP]IDENTITY command to enable IPv6 autoconfiguration for an interface.
