Configuring an IPv6 global unicast address
Configure an IPv6 global unicast address by using the following ways:
• 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.
NOTE:
•
You can configure multiple IPv6 global unicast addresses with different prefixes on an interface.
• A manually configured global unicast address takes precedence over an automatically generated one.
If a global unicast address has been automatically generated on an interface when you manually
configure another one with the same address prefix, the latter overwrites the previous. The overwritten
automatic global unicast address will not be restored even if the manual one is removed. Instead, a new
global unicast address will be automatically generated based on the address prefix information in the
RA message that the interface receives at the next time.
EUI-64 IPv6 addressing
Follow these steps to configure an interface to generate an EUI-64 IPv6 address:
