This document describes a mechanism to encapsulate IPv6 packets over the
Link-Local Discovery Protocol (LLDP).  The LLDP is a single layer-two
protocol and is never forwarded, which is a desireable property when
building the IPv6-over-IPsec-over-IPv6-Link-Local tunnels that make
up the ANIMA Autonomic Control Plane (ACP).
      This unorthodox encapsulation avoids unwanted interactions between the ACP
packets and native packet forwarding engines, as well as being safe for
layer-2 switches which might otherwise have no IPv6 capabilities.
