RFC 7419
Title: Common Interval Support in Bidirectional
Forwarding Detection

Bidirectional Forwarding Detection (BFD) requires that messages be
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.
This document is a product of the Bidirectional Forwarding Detection Working Group of the IETF.
