    abstract =  {This document specifies an extended application of the BFD Echo function for path MTU verification or detection, while preserving its original purpose for detecting forwarding failures. This document defines a process to vary the length of some BFD Echo packets periodically to accomplish this Path MTU verification or detection.},
