Abstract

See full text

In some implementations, a first packet forwarding device (PFD) may obtain a probe packet. The first PFD may replicate the probe packet forming multiple copies of the probe packet. The first PFD may transmit, to the first PFD and to multiple other PFDs, the multiple copies of the probe packet. The first PFD may receive a first copy of the probe packet and multiple response packets, with the first copy of the probe packet originating at the first PFD, and with each of the multiple response packets originating at a respective one of the multiple other PFDs based on the respective one of the multiple other PFDs receiving one of the multiple copies of the probe packet. The first PFD may determine, based on the first copy of the probe packet and the multiple response packets, a status of multiple links associated with the first PFD.
