IPv6 global addresses are unique, globally routable addresses used on the public internet. To configure an interface on a router with an IPv6 global address, there are several methods available. The three methods that accomplish this task are:
A. Use stateless autoconfiguration to assign only the 64 bit interface ID. Stateless autoconfiguration allows a device to automatically generate its own interface ID based on its MAC address or a random number. The rest of the address is obtained from the network prefix advertised by a router on the network. In this method, the interface ID is only 64 bits, and the network prefix is obtained from the router's advertisement. The global IPv6 address is formed by combining the interface ID with the network prefix.
B. Use stateful autoconfiguration to assign only the 64 bit interface ID. Stateful autoconfiguration allows a device to obtain its IPv6 configuration from a DHCPv6 server. In this method, the DHCPv6 server provides only the 64-bit interface ID, and the network prefix is obtained from the router's advertisement. The global IPv6 address is formed by combining the interface ID with the network prefix.
C. Use stateful autoconfiguration to assign the entire global IPv6 address. In this method, the entire IPv6 address, including the network prefix and interface ID, is obtained from a DHCPv6 server. The DHCPv6 server provides the complete address, and the device configures the interface with the provided address.
D. Use a statically assigned global IPv6 address. A static IPv6 address is manually configured on the device's interface. This method requires the network administrator to manually assign the network prefix and interface ID.
E. Use stateless autoconfiguration to assign the entire global IPv6 address. This method is not possible because stateless autoconfiguration only generates the interface ID, not the network prefix. The network prefix must be obtained from a router's advertisement.
In conclusion, to configure an interface on a router to use an IPv6 global address, the most common methods are stateless and stateful autoconfiguration. The network administrator can choose to use a DHCPv6 server to assign the entire address or use stateless autoconfiguration to generate the interface ID and obtain the network prefix from a router's advertisement. A static IPv6 address can also be manually configured if required.
