Hi Greg and the WG, We have update draft-ali-spring-bfd-sr-policy to address comments we received on the list or during WG session presentation. This includes comment on controlling the return path.
Can you please review the changes and advise of your comments? Thanks Regards … Zafar From: "[email protected]" <[email protected]> Date: Monday, October 22, 2018 at 6:19 PM To: "Nagendra Kumar Nainar (naikumar)" <[email protected]>, "Ketan Talaulikar (ketant)" <[email protected]>, "Zafar Ali (zali)" <[email protected]>, "Carlos Pignataro (cpignata)" <[email protected]>, "Clarence Filsfils (cfilsfil)" <[email protected]>, "Nagendra Kumar Nainar (naikumar)" <[email protected]> Subject: New Version Notification for draft-ali-spring-bfd-sr-policy-02.txt A new version of I-D, draft-ali-spring-bfd-sr-policy-02.txt has been successfully submitted by Nagendra Kumar Nainar and posted to the IETF repository. Name: draft-ali-spring-bfd-sr-policy Revision: 02 Title: Bidirectional Forwarding Detection (BFD) for Segment Routing Policies for Traffic Engineering Document date: 2018-10-22 Group: Individual Submission Pages: 11 URL: https://www.ietf.org/internet-drafts/draft-ali-spring-bfd-sr-policy-02.txt Status: https://datatracker.ietf.org/doc/draft-ali-spring-bfd-sr-policy/ Htmlized: https://tools.ietf.org/html/draft-ali-spring-bfd-sr-policy-02 Htmlized: https://datatracker.ietf.org/doc/html/draft-ali-spring-bfd-sr-policy Diff: https://www.ietf.org/rfcdiff?url2=draft-ali-spring-bfd-sr-policy-02 Abstract: Segment Routing (SR) allows a headend node to steer a packet flow along any path using a segment list which is referred to as a SR Policy. Intermediate per-flow states are eliminated thanks to source routing. The header of a packet steered in an SR Policy is augmented with the ordered list of segments associated with that SR Policy. Bidirectional Forwarding Detection (BFD) is used to monitor different kinds of paths between node. BFD mechanisms can be also used to monitor the availability of the path indicated by a SR Policy and to detect any failures. Seamless BFD (S-BFD) extensions provide a simplified mechanism which is suitable for monitoring of paths that are setup dynamically and on a large scale. This document describes the use of Seamless BFD (S-BFD) mechanism to monitor the SR Policies that are used for Traffic Engineering (TE) in SR deployments. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
