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.
NOTE:
Before you modify the existing IPv6 address of an interface for an IPv6 address in the same network
segment as the interface, remove the existing address and reconfigure a new one. Otherwise, address
conflict might lead to an address modification failure.
Enabling IPv6
Enable IPv6 before you perform any IPv6-related configuration. Without IPv6 enabled, an interface
cannot forward IPv6 packets even if it has an IPv6 address configured.
To enable IPv6:

Configuring an IPv6 global unicast address
Configure an IPv6 global unicast address by using the following options:
• EUI-64 IPv6 addressing—The IPv6 address prefix of an interface is manually configured, and the
interface identifier is generated automatically by the interface.
• Manual configuration—The IPv6 global unicast address is configured manually.
• Stateless address autoconfiguration—The IPv6 global unicast address is generated automatically
based on the address prefix information contained in the RA message.
• Prefix-generated address—The IPv6 global unicast address is generated automatically based on
the applied IPv6 prefix, specified sub-prefix bit, and host bit information.
You can configure multiple IPv6 global unicast addresses with different prefixes on an interface.
