AUTOMATIC RECOVERY FROM DUPLICATE NETWORK ADDRESSES

Abstract:

A network device in a network may determine a tentative network address for a network interface of the network device and may determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the tentative network address is duplicative of a network address assigned to another network interface in the network, the network device may store an indication of the other network interface. In response to receiving an indication that a new network address is assigned to the other network interface, the network device may re-determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the network device determines that the tentative network address is not duplicative of any one of the plurality of network addresses in the network, the network device may assign the tentative network address to the network interface.
