dhcpv6 client information-request

Function

The dhcpv6 client information-request command enables an interface to obtain configuration parameters (not including IPv6 addresses) using stateless DHCPv6 address autoconfiguration.

The undo dhcpv6 client information-request command disables an interface from obtaining configuration parameters (not including IPv6 addresses) using stateless DHCPv6 address autoconfiguration.

By default, the interface is disabled from obtaining configuration parameters (not including IPv6 addresses) using stateless DHCPv6 address autoconfiguration.

Usage Guidelines

Usage Scenario

The dhcpv6 client information-request command is used on the DHCPv6 client. After you run the dhcpv6 client information-request on the device that functions as a DHCPv6 client, IPv6 addresses are generated based on the Route Advertisement (RA) packets. The DHCPv6 server provides other configuration parameters such as IP addresses of the DNS, and SNTP servers except for IPv6 addresses and the interval for updating configuration parameters.

Prerequisites

IPv6 functions have been enabled globally using the ipv6 command in the system view.
IPv6 functions have been enabled on interfaces using the ipv6 enable command in the interface view.
The IPv6 link-local address has been configured using the ipv6 address auto link-local or ipv6 address ipv6-address link-local command in the interface view.

Example

# Configure the DHCPv6 client to obtain configuration parameters using stateless DHCPv6 address autoconfiguration on the interface VLANIF100.

<HUAWEI> system-view
[HUAWEI] ipv6 
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] ipv6 enable
[HUAWEI-Vlanif100] ipv6 address auto link-local
[HUAWEI-Vlanif100] dhcpv6 client information-request

# Configure the DHCPv6 client to obtain configuration parameters using stateless DHCPv6 address autoconfiguration on the interface

<HUAWEI> system-view
[HUAWEI] ipv6

[HUAWEI-GigabitEthernet0/0/1] undo portswitch
[HUAWEI-GigabitEthernet0/0/1] ipv6 enable
[HUAWEI-GigabitEthernet0/0/1] ipv6 address auto link-local
