COMMAND USAGE
◆ To connect to a larger network with multiple subnets, you must
configure a global unicast address. This address can be automatically
configured using this command, or it can be manually configured using
the ip ipv6 setup command (page 278).
◆ When autoconfiguration is enabled, the network portion of the address
is based on prefixes received in IPv6 router advertisement messages
observed on the local interface, and the host portion is automatically
generated using the modified EUI-64 form of the interface identifier;
i.e., the switch's MAC address.
