Manual Configuration - HP 6125XLG Layer 3-Ip Services Configuration Manual

Step
1. Enter system view.
2. Enter interface view.
3. Configure the interface to
generate an EUI-64 IPv6
address.

Manual configuration

To configure an IPv6 global unicast address for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 global
unicast address for the
interface.
Stateless address autoconfiguration
To configure an interface to generate an IPv6 address through stateless address autoconfiguration:
Step
1. Enter system view.
2. Enter interface view.
3. Enable stateless address
autoconfiguration.
After this configuration, the interface automatically generates an IPv6 global unicast address by using
the address prefix in the received RA message and the interface ID. On an IEEE 802 interface (such as
an Ethernet interface or a VLAN interface), the interface ID is generated based on the MAC address of
the interface and is globally unique. An attacker can exploit this rule to identify the sending device easily.
To fix the vulnerability, you can configure the temporary address function. With this function, an IEEE 802
interface generates the following addresses:
Public IPv6 address—Includes the address prefix in the RA message and a fixed interface ID
•
generated based on the MAC address of the interface.
• Temporary IPv6 address—Includes the address prefix in the RA message and a random interface
ID generated through MD5.

By default, no IPv6 global unicast
address is configured on an interface.
Using the undo ipv6 address auto
command on an interface removes all
IPv6 global unicast addresses and
link-local addresses that are
automatically generated on the
interface.
