Working Group, This draft was briefly mentioned as part of the IDR WG presentation on RS-BFD that I am a co-author on. That presentation is supposed to be linked here, but is not coming up. Hopefully it's a transient error:
https://datatracker.ietf.org/meeting/99/materials/slides-99-idr-03-idr-rs-bfd-ietf99 A simplified version of the discussion is roughly: - In Internet Exchange Point environments, monitoring BGP next-hop reachability via BFD is desirable. - Since these next-hops may not be symmetrically distributed in BGP between the two end systems via the route server, additional help is needed to permit both sides of a normal RFC 5881 session bootstrap itself. The draft mentioned below attempts to resolve this scenario by permitting a "wildcard" single-hop BFD session be created for interfaces in environments such as a this IXP environment. It may be useful outside of the IXP use case. -- Jeff On Sun, Jul 30, 2017 at 07:35:31PM -0700, Enke Chen wrote: > Hi, Folks: > > Please let us know if you have any comments on the draft. > > Thanks. -- Enke > > -------- Forwarded Message -------- > Subject: I-D Action: draft-chen-bfd-unsolicited-01.txt > Date: Sun, 30 Jul 2017 19:26:10 -0700 > From: [email protected] > Reply-To: [email protected] > To: [email protected] > > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > > > Title : Unsolicited BFD for Sessionless Applications > Authors : Enke Chen > Naiming Shen > Robert Raszuk > Filename : draft-chen-bfd-unsolicited-01.txt > Pages : 6 > Date : 2017-07-30 > > Abstract: > For operational simplification of "sessionless" applications using > BFD, in this document we present procedures for "unsolicited BFD" > that allow a BFD session to be initiated by only one side, and be > established without explicit per-session configuration or > registration by the other side (subject to certain per-interface or > per-router policies). > > > > The IETF datatracker status page for this draft is: > https://datatracker.ietf.org/doc/draft-chen-bfd-unsolicited/ > > There are also htmlized versions available at: > https://tools.ietf.org/html/draft-chen-bfd-unsolicited-01 > https://datatracker.ietf.org/doc/html/draft-chen-bfd-unsolicited-01 > > A diff from the previous version is available at: > https://www.ietf.org/rfcdiff?url2=draft-chen-bfd-unsolicited-01 > > > 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. > > Internet-Drafts are also available by anonymous FTP at: > ftp://ftp.ietf.org/internet-drafts/ > > _______________________________________________ > I-D-Announce mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/i-d-announce > Internet-Draft directories: http://www.ietf.org/shadow.html > or ftp://ftp.ietf.org/ietf/1shadow-sites.txt
