Techniques herein define a simple, but very useful, extension to hop-by-hop signaling that can be utilized to determine a failed node in a network, which may help to reduce fault detection time. In one instance, techniques described herein may involve multicast Label Distribution Protocol (mLDP)-based signaling, however, other replication technologies that involve underlay signaling may be utilized in accordance with techniques described herein.
