R211x-HP Flexfabric 11900 Layer 3 - IP Services Command Reference

205
• 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 VLAN-interface 100 to automatically generate a link-local address.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] 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 EUI-64 IPv6 address of the interface.
Syntax
ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length } eui-64
undo ipv6 address [ ipv6-address prefix-length | ipv6-address/prefix-length ] eui-64

Parameters
ipv6-address/prefix-length: Specifies an IPv6 address and IPv6 prefix length. The ipv6-address and
prefix-length arguments jointly specify the prefix of an EUI-64 IPv6 address. The value range for the
prefix-length argument is 1 to 64.
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 VLAN-interface 100. The prefix 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.
