This document defines two new DHCPv6 messages: Reconfigure-Request and Reconfigure-Reply. The Reconfigure-Request message is sent by a DHCPv6 relay agent to notify a DHCPv6 server about a configuration information change@ so that the DHCPv6 server can send a Reconfigure message accordingly. The Reconfigure-Reply message is used by the server to acknowledge the receipt of the Reconfigure-Request message.
