The IESG has received a request from the Bidirectional Forwarding Detection WG (bfd) to consider the following document: - 'Common Interval Support in BFD' <draft-ietf-bfd-intervals-03.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-09-01. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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 interval value to run BFD sessions. This document defines 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 file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-bfd-intervals/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-bfd-intervals/ballot/ No IPR declarations have been submitted directly on this I-D.
