z For detailed information about the ipv6 address auto command, refer to IPv6 Basics
Configuration Commands in the Layer 3 - IP Services Command Reference.
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.
Configuring the DHCPv6 Relay Agent
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.
Configuration Prerequisites
Before configuring DHCPv6 relay agent, you need to use the ipv6 command to enable IPv6.
Configuration Procedure
Follow these steps to configure the DHCPv6 relay agent:
