Assigning IPv6 addresses to interfaces
This section describes how to configure an IPv6 global unicast address, an IPv6 link-local address,
and an IPv6 anycast address.
Configuring an IPv6 global unicast address
Use one of the following methods to configure an IPv6 global unicast address for an interface:
•
EUI-64 IPv6 address—The IPv6 address prefix of the interface is manually configured, and the
interface ID is generated automatically by the interface.
•
Manual configuration—The IPv6 global unicast address is manually configured.
•
Stateless address autoconfiguration—The IPv6 global unicast address is generated
automatically based on the address prefix information contained in the RA message.
•
Prefix-specific address autoconfiguration—The IPv6 global unicast address is generated
automatically based on the prefix specified by its ID. The prefix can be manually configured or
obtained through DHCPv6.
You can configure multiple IPv6 global unicast addresses on an interface.
Manually configured global unicast addresses (including EUI-64 IPv6 addresses) take precedence
over automatically generated ones. If you manually configure a global unicast address with the same
address prefix as an existing global unicast address on an interface, the manually configured one
