generated address. If you first use manual assignment and then automatic generation, the automatically
generated link-local address does not take effect and the link-local address of an interface is still the
manually assigned address. If you delete the manually assigned address, the automatically generated
link-local address is validated. For more information about manually assignment of an IPv6 link-local
address, see the ipv6 address link-local command.
Examples
# Configure GigabitEthernet 3/1/1 to automatically generate a link-local address.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/1/1
[Sysname-GigabitEthernet3/1/1] ipv6 address auto link-local
ipv6 address eui-64
Use ipv6 address eui-64 to configure an EUI-64 IPv6 address for an interface.
Use undo ipv6 address eui-64 to remove the configured EUI-64 IPv6 address for the interface.
Syntax
ipv6 address ipv6-address/prefix-length eui-64
undo ipv6 address ipv6-address/prefix-length eui-64
Default
No EUI-64 IPv6 address is configured for an interface.
Views

Default command level
2: System level
Parameters
ipv6-address/prefix-length: IPv6 address and IPv6 prefix length. The ipv6-address and prefix-length
arguments jointly specify the prefix of an EUI-64 IPv6 address.
Usage guidelines
An EUI-64 IPv6 address is generated based on the specified prefix and the automatically generated
interface identifier and is displayed by using the display ipv6 interface command.
The prefix length of an EUI-64 IPv6 address cannot be greater than 64.
Examples
# Configure an EUI-64 IPv6 address for GigabitEthernet 3/1/1. The prefix length of the address is the
same as that of 2001::1/64, and the interface ID is generated based on the MAC address of the device.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/1/1
[Sysname-GigabitEthernet3/1/1] ipv6 address 2001::1/64 eui-64
ipv6 address link-local
Use ipv6 address link-local to configure a link-local address for the interface.
