Claim 12:
13. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
generating a first probe packet addressed to a first destination node of a first expired data packet;
sending the first probe packet in a network towards the first destination node;
receiving the first probe packet;
based on receiving the first probe packet:
identifying In-situ Operations, Administration, and Management (IOAM) information in the first probe packet;
identifying one or more intermediary nodes in a first routing loop based, at least in part, on the IOAM information;
generating a first report indicating a presence of the first routing loop and identifying the one or more intermediary nodes in the first routing loop; and
sending, to an administrator, the first report;

generating a second probe packet addressed to a second destination node of a second expired data packet;
sending the second probe packet in the network towards the second destination node; and
upon expiration of a wait time after sending the second probe packet without having received the second probe packet, sending, to the administrator, a second report indicating an absence of a second routing loop.
