One double colon may be used in the address to indicate the appropriate
number of zeros required to fill the undefined fields. And the address prefix
must be in the range of FE80~FEBF.
◆ The address specified with this command replaces a link-local address that was
automatically generated for the interface.

one link-local address per interface.
