Abstract
Mac learning for cross-site layer-2 connectivity. Some embodiments provide a method for enabling data traffic to be sent between across which a logical network spans. A logical network segment (i.e., a layer-2 network segment such as a logical switch) spans at least two sites via tunnels between network elements deployed in the sites that operate as bridges (or 2-port switches) to pass data traffic between the sites without leaving the logical network segment. Because these network elements operate similarly to bridges, they are not assigned network (layer 3) addresses (e.g., IP addresses). In order to send address resolution protocol (ARP) requests to a router in one site, the network element in another site uses a network address of one of the data compute nodes (DCNs) operating in its site that is connected to the logical network segment spanning the two sites.
