Hi Gergory,
Fisrt, thanks for questions.
Your question: How a RR avoid sending ASBR info(carried by EBGP summary session
nlri) to non-PCE router?
In our I-D, we defined a new AFI/SAFI pair for such EBGP summary session nlri.
So when a router begins to set up a connecton with RR, they will do capability
negotiation. If the router dosen't carry such new AFI/SAFI info in the open
message(indicates it's a non-PCE router or a router which doesn't consern about
such info), then the RR will not send any such ASBR info to that router.
Any feedback and comments are welcome.
Best regards,
Mach Chen

Title : Locate ASBR in PCE

The ability to compute constrained shortest Traffic Engineering (TE)
Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS)
and Generalized MPLS (GMPLS) networks across multiple domains has
been identified as a key requirement. This document specifies a
procedure for an inter-AS PCE to locate boundary node within its
domain dynamically, which is used for path computation.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
