z Manual configuration: IPv6 site-local addresses or aggregatable global unicast addresses are
configured manually.
z Stateless address autoconfiguration: IPv6 global unicast addresses are generated automatically
based on the address prefix information contained in the RA message.
IPv6 link-local addresses can be configured in either of the following ways:
z Automatic generation: The device automatically generates a link-local address for an interface
according to the link-local address prefix (FE80::/10) and the link-layer address of the interface.
z Manual assignment: IPv6 link-local addresses can be assigned manually.
To avoid link-local address conflicts, it is recommended to use the automatic generation method.
