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 FYI: A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Locate ASBR in PCE Author(s) : R. Zhang, M. Chen Filename : draft-zhang-pce-locate-asbr-00.txt Pages : 8 Date : 2006-10-12 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.

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv at ietf.org. In the body type: "FILE /internet-drafts/draft-zhang-pce-locate-asbr-00.txt". 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 Internet-Draft. <ftp://ftp.ietf.org/internet-drafts/draft-zhang-pce-locate-asbr-00.txt> _______________________________________________ I-D-Announce mailing list I-D-Announce at ietf.org https://www1.ietf.org/mailman/listinfo/i-d-announce _______________________________________________ Pce mailing list Pce at lists.ietf.org https://www1.ietf.org/mailman/listinfo/pce -------------------------------------------------------------------------------- Prev by Date: [PCE] Inter-AS PCE Path Sequence Autoexplore Next by Date: RE: [PCE] About ASBR locate Previous by thread: [PCE] Inter-AS PCE Path Sequence Autoexplore Next by thread: RE: [PCE] About ASBR locate Index(es): Date Thread Note: Messages sent to this list are the opinions of the senders and do not imply endorsement by the IETF. _______________________________________________ Pce mailing list Pce@lists.ietf.org https://www1.ietf.org/mailman/listinfo/pce
