ABSTRACT:
Embodiments of the present invention provide link-local IPv4 addressing across multiple interfaces of a network-node. During operation, the network-node broadcasts an address resolution protocol (ARP) request packet on multiple interfaces which asks for the hardware address of a network node whose link-local IPv4 address is Y. In response, the network-node receives an ARP-reply packet on an interface from a target network-node. If Y is present in the ARP cache and is associated with a different interface, the source network-node chooses a winner interface, and updates the ARP cache so that Y is associated with the winner interface. The network-node sends one or more contention-resolution packets on the loser interface to cause a loser network-node to choose another link-local IPv4 address for itself.
