9.3 Configuring an IPv6 Address for an Interface

Assigning an IPv6 address to a device on a network enables the device to communicate with the
other devices on the network.

9.3.1 Establishing the Configuration Task

This section describes the applicable environment, pre-configuration tasks, data preparation, and
configuration procedure for assigning an IPv6 address to an interface.
Applicable Environment
When a device communicates with an IPv6 device, you need to configure IPv6 address for the
interface.
An EUI-64 address has the same function as an global unicast address. The difference is that
only the network bits need to be specified for the EUI-64 address and the host bits are transformed
from the MAC addresses of the interface while a complete 128-bit address need to be specified
for the global unicast address. Note that the prefix length of the network bits in an EUI-64 address
must not be longer than 64 bits.
The EUI-64 address and the global unicast address can be configured simultaneously or
alternatively. However, the IP addresses configured for one interface cannot be in the same
network segment.
Pre-configuration Tasks
Before configuring IPv6 addresses, complete the following tasks:
