Abstract
In one implementation, a method is disclosed comprising: identifying, based on path tracing probes sent through a network, data plane forwarding paths between nodes in the network; determining, based on topology data for the network, expected protocol-based paths between the nodes; detecting, based on a comparison of the data plane forwarding paths and the expected protocol-based paths between the nodes, a routing anomaly in the network when the data plane forwarding paths and the expected protocol-based paths differ; and causing performance of a mitigation action in the network with respect to the routing anomaly.
