        Title           : Propagating Explicit Congestion Notification Across IP Tunnel Headers Separated by a Shim

Abstract:
   RFC 6040 on "Tunnelling of Explicit Congestion Notification" made the
   rules for propagation of ECN consistent for all forms of IP in IP
   tunnel.  This specification updates RFC 6040 to clarify that its
   scope includes tunnels where two IP headers are separated by at least
   one shim header that is not sufficient on its own for wide area
   packet forwarding.  It surveys widely deployed IP tunnelling
   protocols separated by such shim header(s) and updates the
   specifications of those that do not mention ECN propagation (L2TPv2,
   L2TPv3, GRE and Teredo).  This specification also updates RFC 6040
   with configuration requirements needed to make any legacy tunnel
   ingress safe.
