Configuring The Dhcpv6 Relay Agent; Configuration Prerequisites; Configuration Procedure - 3Com S7906E Configuration Manual

Enable IPv6 stateless address
autoconfiguration
For detailed information about the ipv6 address auto command, refer to IPv6 Basics Commands
in the IP Services Volume.
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.
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.
