  • Patent number: 11985057
    Abstract: To achieve impact-less re-routing of traffic towards non best-paths in a network, two locator routes are originated for each network fabric: a primary locator and a secondary locator. In a steady state, the forwarding state on each router is created by recursion of endpoints identifiers through their originating location's primary locator-route. Secondary locator routes are not used in the steady state. At a desired point, a steering route is injected into the network device to redirect routing from the primary locator route to the secondary locator route. The secondary locator route has a different resultant port from the primary locator route to redirect incoming packets on a different network path.

  • Patent number: 10225175
    Abstract: Disclosed are system, methods, and non-transitory computer readable media for accurately calculating a default gateway of an endpoint without probing the endpoint for the configured values to determine the path between network elements. Tracing the path of a flow in a network and displaying that on a user interface is extremely useful for network troubleshooting purposes. In order to find the gateway the flow would take out of the L2 domain, the endpoint's L2 default gateway is required. Usually the L2 gateway for network endpoints is configured on the endpoints themselves and this information cannot be accessed by network controllers (e.g., APIC-EM) directly. In such cases APIC-EM needs to determine the L2 gateway based on the information available to it from the network elements, instead of the endpoints themselves.
