Manual Configuration - HP A7500 Series Configuration Manual

EUI-64 IPv6 addressing
Follow these steps to configure an interface to generate an EUI-64 IPv6 address:
To do...
Enter system view
Enter interface view
Configure the interface to
generate an EUI-64 IPv6
address

Manual configuration

Follow these steps to specify an IPv6 address manually for an interface:
To do...
Enter system view
Enter interface view
Configure an IPv6 address
manually
Stateless address autoconfiguration
Follow these steps to configure an interface to generate an IPv6 address by using stateless address
autoconfiguration:
To do...
Enter system view
Enter interface view
Configure an IPv6 address to be
generated through stateless
address autoconfiguration
NOTE:
Using the undo ipv6 address auto command on an interface removes all IPv6 global unicast addresses
automatically generated on the interface.
With stateless address autoconfiguration enabled on an interface, the device automatically generates an
IPv6 global unicast address by using the address prefix information in the received RA message and the
interface ID. On an IEEE 802 interface (such as a VLAN interface), the interface ID is generated based
on the MAC address of the interface, and is globally unique. As a result, the interface ID portion of the
IPv6 global address remains unchanged and exposes the sender. An attacker can further exploit
communication details such as the communication peer and time.
To fix the vulnerability, configure the temporary address function that enables the system to generate and
use temporary IPv6 addresses with different interface ID portions on an interface. With this function
Use the command...
system-view
interface interface-type
interface-number
ipv6 address
ipv6-address/prefix-length eui-64
Use the command...
system-view
interface interface-type
interface-number
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
Use the command...
system-view
interface interface-type
interface-number
