A first customer edge (CE) network device positioned in a first customer network may be configured to perform the techniques. The first CE network device may comprise a control unit configured to execute an instance of a network protocol to detect faults between the first CE network device and a second CE network device positioned in a second customer network. The first CE network device may also comprise an interface configured to transmit a message to the second CE network device via the instance of the network protocol signaling that a provider edge (PE) network device is going to become nonoperational. The PE network device may be positioned in an intermediate network providing interconnectivity between the first customer network and the second customer network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overload functionality in overlay networks using fault detection protocols","description":"In general, techniques are generally described for reducing or preventing transient black-holing of network traffic in an overlay network.
