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 an actual tunnel endpoint address for an endpoint in communication with a network fabric via a leaf node in the network fabric, identify a reference tunnel endpoint address for the endpoint, and determine that there is an inconsistency based on a comparison of the actual tunnel endpoint address with the reference tunnel endpoint address.

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 first endpoint information about endpoints in the network from one or more spine nodes in a network and second endpoint information about the endpoints in the network from one or more leaf nodes in the network. The network assurance appliance compares the first endpoint information with the second endpoint information and generates an event based on the comparison.

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.

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 identify an endpoint in a bridge domain is associated with at least one subnet, retrieve at least one IP address associated with the endpoint, determine whether the at least one IP address is within the at least one subnet, and determine there is an inconsistency when the at least one IP address is not within the at least one subnet.
