1.3.2 Configuring an IPv6 Unicast Address

IPv6 site-local addresses and aggregatable global unicast addresses can be
configured in the following ways:
EUI-64 format: When the EUI-64 format is adopted to form IPv6 addresses, the
IPv6 address prefix of an interface is the configured prefix and the interface
identifier is derived from the link-layer address of the interface.
Manual configuration: IPv6 site-local addresses or aggregatable global unicast
addresses are configured manually.
IPv6 link-local addresses can be configured in either of the following ways:
Automatic generation: The device automatically generates a link-local address for
an interface according to the link-local address prefix (FE80::/64) and the
link-layer address of the interface.
Manual assignment: IPv6 link-local addresses can be assigned manually.
Follow these steps to configure an IPv6 unicast address:

Remarks
—
—
Required to use
either command.
By default, no
site-local address or
aggregatable global
unicast address is
configured for an
interface.
Optional
By default, after an
IPv6 site-local
address or
aggregatable global
unicast address is
configured for an
interface, a link-local
address will be
generated
automatically.
