Hi, All PCE experts:

The main updates of this version are the followings:
1.	Add the "Tunnel Source IP Address/Destination IP Address" fields
within the BPI(BGP Peer Info) Object to indicate the tunnel endpoints when
traffic between the head and end needs to be via a tunnel.
There are situation that the traffic should be forwarded via one tunnel to
ensure only the traffic that match both (source prefix, destination prefix)
needs to be QoS assured.
The (source prefix, destination prefix) is advertised via the associated BGP
2.	Introduce the "T" bit in the BPI Object to indicate whether the
traffic will be passed via the tunnel or not.
3.	The info within the EPR(Explicit Peer Route) Object will also be
filled based on the "T" bit in BPI Object.
4.	Other editorial changes which were highlighted at
Look forwards to your comments on these changes.

And, if there is no comments on the above updates, we would like to ask the
WG to begin the WG Last Call for this document.

Thanks in advance.

Best Regards

   This document defines the Path Computation Element Communication
   Protocol (PCEP) extension for Central Control Dynamic Routing (CCDR)
   based application in Native IP network.  The scenario and framework
   of CCDR in native IP is described in [RFC8735] and [RFC8821].  This
   draft describes the key information that is transferred between Path
   Computation Element (PCE) and Path Computation Clients (PCC) to
   accomplish the End to End (E2E) traffic assurance in Native IP
   network under central control mode.
