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.
