RE: I-D Action: draft-lin-sbfd-path-consistency-over-srv6-02.txt

Hi WG & Chairs

  We updated the draft: draft-lin-sbfd-path-consistency-over-srv6-02.

  https://datatracker.ietf.org/doc/draft-lin-sbfd-path-consistency-over-srv6/

  This draft describes the method of keep the path consistency of sbfd in detecting SRv6 policy through Path Segment,

  and this draft has been presented at the spring meeting of IETF113.

  The new version modified the description of sbfd packet encapsulation refer to [draft-liu-bfd-srv6-policy-encap].

  Any comments on the draft are welcome.

  Thanks,

  Changwang lin

Abstract:
   Bidirectional Forwarding Detection (BFD) can be used to monitor
   paths between nodes. Seamless BFD (S-BFD) provides a simplified
   mechanism which is suitable for monitoring of paths that are setup
   dynamically and on a large scale network. In SRv6, when a headend
   use S-BFD to monitor the segment list/CPath of SRv6 Policy, the
   forward path of control packet is indicated by segment list, the
   reverse path of response control packet is via the shortest path
   from the reflector back to the initiator (headend) as determined by
   routing. The forward path and reverse path of control packet are
   likely inconsistent going through different intermediate nodes or
   links. This document describes a method to keep the forward path and
   reverse path of S-BFD consistent when detecting SRv6 Policy.
