A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Bidirectional Forwarding Detection Working Group of the IETF. Title : Common Interval Support in Bidirectional Forwarding Detection Authors : Nobo Akiya Marc Binderberger Greg Mirsky Filename : draft-ietf-bfd-intervals-05.txt Pages : 8 Date : 2014-10-14 Abstract: Bidirectional Forwarding Detection (BFD) requires that messages are transmitted at regular intervals and provides a way to negotiate the interval used by BFD peers. Some BFD implementations may be restricted to only support several interval values. When such BFD implementations speak to each other, there is a possibility of two sides not being able to find a common value for the interval to run BFD sessions. This document updates RFC 5880 by defining a small set of interval values for BFD that we call "Common Intervals", and recommends implementations to support the defined intervals. This solves the problem of finding an interval value that both BFD speakers can support while allowing a simplified implementation as seen for hardware-based BFD. It does not restrict an implementation from supporting more intervals in addition to the Common Intervals. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-intervals/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-bfd-intervals-05 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-bfd-intervals-05 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.
