Abstract: There is provided a router for use in a datacenter, the router including a frame receiving module operative to receive a traffic frame and a frame forwarding module operative to forward the traffic frame to a second router in a second datacenter if a Destination Media Access Control (DMAC) address included in the traffic frame is different from all of the following: a Burned in Address of the router; a Burned in Address of at least one server associated with the router; a Media Access Control (MAC) address of one of a Hot Standby Routing Protocol (HSRP) group and a Virtual Router Redundancy Protocol (VRRP) group of the router; and a MAC address of one of a HSRP group and a VRRP group of a subnet hosted by the router.
