* Technical Summary

This draft describes how a Point to Point Protocol (PPP), or High-
Level Data Link Control (HDLC) Protocol Data Units over an
MPLS network without terminating the PPP/HDLC protocol.

This enables service providers to offer "emulated" HDLC, or PPP
link services over existing MPLS networks. This document specifies
the encapsulation of PPP/HDLC Packet Data Units (PDUs) within
a PW.

* Working Group Summary

This work has been thoroughly analysed by the working group
and there is consensus for the design.

* Protocol Quality

There are many implementations of this protocol, and it is
in operational service.

Note to RFC Editor
 

OLD:

  It is also recommended that PPP devices MUST NOT negotiate PPP MRUs 
  larger than that of the AC MTU. 

NEW:

  It is also RECOMMENDED that the PPP devices be configured to not
  negotiate PPP MRUs larger that of the AC MTU.
