Abstract: Disclosed are systems, methods, and computer-readable media for assuring tenant forwarding in a network environment. Network assurance can be determined in layer 1, layer 2 and layer 3 of the networked environment including, internal-internal (e.g., inter-fabric) forwarding and internal-external (e.g., outside the fabric) forwarding in the networked environment. The network assurance can be performed using logical configurations, software configurations and/or hardware configurations

Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve, from a first leaf node in a network, first endpoint information for a first set of endpoints connected to the first leaf node, wherein the first set of endpoints includes a virtual port channel (VPC) endpoint. The network assurance appliance retrieves second endpoint information from a second node in the network, compares the first endpoint information with the second endpoint information, and identifies an inconsistency when the first endpoint information and the second endpoint information do not match.

Abstract: Systems, methods, and computer-readable media for identifying and categorizing epoch events between a first epoch and a second epoch. Epoch event data for a first epoch and a second epoch is retrieved. The retrieved epoch event data is categorized to determine event category, specific event, and respective object identification. The categorized first and second epoch event data is then labeled to identify new, resolved, and persistent epoch events over multiple epochs.

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.

Abstract: Systems, methods, and computer-readable media for validating routing table information in a network. A network assurance appliance may be configured to retrieve implemented MP-BGP configuration data from a plurality of nodes in a network fabric and reference MP-BGP configuration data from a network controller. The network assurance appliance compares the implemented MP-BGP configuration data with the reference MP-BGP configuration data and determines that there is a MP-BGP misconfiguration of the implemented MP-BGP configuration data based on differences in the implemented MP-BGP configuration data and the reference MP-BGP configuration data.

Abstract: Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve a configured static endpoint information in a logical model of a network from a network controller and connected static endpoint information from one or more nodes in the network. The network assurance appliance determines that there is an inconsistency based on a comparison of the configured static endpoint information and the connected static endpoint information and generating an event specifying the inconsistency.
