Abstract
A method and apparatus of a device that notifies another device of a failed device is described. In an exemplary embodiment, a network element detects that a first device is unavailable, where the network element couples the first device to the second device. In response to detecting that the first device is unavailable, the network element configures a proxy for the first device. The network element additionally receives network data that is destined for the first device, where the second device originated the network data. If the proxy can process the network data, the network element transmits a response to the second device from the proxy, where the response indicates that the first device is unavailable, where the first response includes an address of the first device. If the proxy cannot process the network data, the network element drops the network data.
