Dear all, 

We have updated the BGP based PCE discovery draft to resolve the comments received during IETF94 meeting. 

The main changes are:

1. Specify the limitation in IGP based discovery, and improve the use cases of BGP based discovery mechanism.
2. Explicitly specify that the interaction between BGP and IGP based discovery is out of scope. 
3. Modify the recommended protocol-ID value for PCE discovery information.
4. Improve the operational considerations.
5. Editorial changes.

Any further review comments are welcome and authors believe this revision is ready for wg adoption. 

Many thanks,
Jie (on behalf of co-authors)

Abstract:
   In networks where Path Computation Element (PCE) is used for
   centralized path computation, it is desirable for the Path
   Computation Clients (PCCs) to automatically discover a set of PCEs
   and select the suitable ones to establish the PCEP session.  RFC 5088
   and RFC 5089 define the PCE discovery mechanisms based on Interior
   Gateway Protocols (IGP).  This document describes several scenarios
   in which the IGP based PCE discovery mechanisms cannot be used
   directly.  In such scenarios, BGP might be suitable, thus this
   document specifies the BGP extensions for PCE discovery.  The BGP
   based PCE discovery mechanism is complementary to the existing IGP
   based mechanisms.
