DHCPv6 Relay Agents [RFC3315] are deployed to forward DHCPv6 messages between clients and servers when they are not on the same IPv6 link and are often implemented alongside a routing function in a common node. A Lightweight DHCPv6 Relay Agent (LDRA) allows Relay Agent Information to be inserted by an access node that performs a link- layer bridging (i.e., non-routing) function. An LDRA resides on the same IPv6 link as the client and a DHCPv6 Relay Agent or server, and is functionally the equivalent of the Layer 2 Relay Agent proposed for DHCPv4 operation in [L2RA].

Lightweight DHCPv6 Relay Agent
This document proposes a Lightweight DHCPv6 Relay Agent (LDRA) that is used to insert relay agent options in DHCPv6 message exchanges identifying client-facing interfaces. The LDRA can be implemented in existing access nodes (such as Digital Subscriber Link Access Multiplexers (DSLAMs) and Ethernet switches) that do not support IPv6 control or routing functions.
