Abstract
Techniques for determine latency, loss, and liveness performance metrics associated with ECMP routes. The techniques may include determining that a TWAMP probe is to be sent from a first node to a second node along an equal-cost multipath ECMP route. In some examples, the first node may generate a packet for sending the TWAMP probe to the second node. The packet may include information specifying a forward path and reverse path to be traversed by the packet. In examples, the first node may send the packet to the second node along the ECMP route and subsequently receive the packet including telemetry data associated with the second node and a midpoint node of the ECMP route. Based at least in part on the telemetry data, the first node may determine a metric indicative of a performance measurement associated with the ECMP route.
