HP VPN Firewall Appliances Network Management Command Reference

710
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 0/1. 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 0/1
[Sysname-GigabitEthernet0/1] 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.
Use undo ipv6 address link-local to remove the configured link-local address for the interface.
Syntax
ipv6 address ipv6-address link-local

Default command level
2: System level
Parameters
ipv6-address: IPv6 link-local address. The first 10 bits of an address must be 1111111010 (binary) . The first
group of hexadecimals in the address must be FE80 to FEBF.
Usage guidelines
Manual assignment takes precedence over automatic generation. If you first adopt automatic generation
and then manual assignment, the manually assigned link-local address overwrites the automatically
generated one. If you first adopt 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 one. If you delete the manually assigned address, the automatically generated
link-local address is validated. For information about automatic generation of an IPv6 link-local address,
see the ipv6 address auto link-local command.
Examples
# Configure a link-local address for GigabitEthernet 0/1.

[Sysname] interface gigabitethernet 0/1
