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 identifier 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.
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 takes effect, but
it does not overwrite the automatically generated address. If you remove the manually configured global
unicast address, the device uses the automatically generated one.
EUI-64 IPv6 address
To configure an interface to generate an EUI-64 IPv6 address:
