Abstract: Access-side loop mitigation may be provided. First, a first edge device may determine that a duplicate host exists on a network. Then the first edge device may detect a loop in response to determining that the duplicate host exists on the network. Detecting the loop may comprise sending a message on a plurality of access-side ports of the first edge device and then receiving, in response to sending the message on the plurality of access-side ports of the first edge device, a response on a first access-side port of the plurality of access-side ports of the first edge device. Next, the first edge device may mitigate the detected loop in response to receiving the response.
