Ballot Text

* 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


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


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