Enable IPv6 stateless address 
autoconfiguration 

Required 

 

z 

For detailed information about the ipv6 address auto command, refer to IPv6 Basics Commands 

in the IP Services Volume. 

z 

With an IPv6 address obtained through stateless address autoconfiguration, a device automatically 

enables the stateless DHCPv6 function to obtain other configuration parameters upon receiving an 

RA message with the “M” flag set to 0 and with the “O” flag set to 1. 

z 

An interface cannot serve as a stateless DHCPv6 client and DHCPv6 relay agent at the same time. 

 

Upon receiving a request from a DHCPv6 client, the interface that operates as a DHCPv6 relay agent 

encapsulates the request into a Relay-forward message and forwards the message to the specified 

DHCPv6 server, which then assigns an IPv6 address and other configuration parameters to the 

DHCPv6 client. 

Before configuring DHCPv6 relay agent, you need to use the ipv6 command to enable IPv6. 

Follow these steps to configure the DHCPv6 relay agent: 

Enter system view 

— 

Enter interface view 

interface interface-type interface-number 

— 

Enable DHCPv6 relay agent 
on the interface and specify 
a DHCPv6 server 

ipv6 dhcp relay server-address 
ipv6-address [ interface interface-type 
interface-number ] 

Required 

By default, DHCPv6 
relay agent is disabled 
and no DHCPv6 
server is specified on 
the interface.
