Abstract: Techniques for providing an extended layer 2 network. Embodiments receive, at a first network device in a first layer 2 network within the extended layer 2 network, a data packet specifying a destination Media Access Control (MAC) address. Upon determining that the destination MAC address is a site virtual MAC (S-VMAC) address, the data packet is forwarded to a second network device in a second layer 2 network within the extended layer 2 network and associated with the S-VMAC address, where the second network device is configured to determine a second destination MAC address for the data packet based on an Internet Protocol (IP) address specified in the data packet, and is further configured to forward the data packet to a destination device associated with the determined second destination MAC address.
