Abstract
Systems, methods, and computer-readable media for validating routing table information in a network. A network assurance appliance may be configured to retrieve routing table information from a plurality of nodes in a network fabric. The routing table information includes path information from at least one source node to at least one destination node. A graph representation of the routing table information is constructed with the at least one destination node as a sink vertex for the graph representation. The network assurance appliance determines, for each leaf node in the network fabric, whether the leaf node can reach the sink vertex based on the graph representation and determines that there is a misconfiguration of the network fabric based on whether each leaf node in the fabric can reach the sink vertex.
