Destination MAC address rewrites for OpenFlow

Some types of network equipment that function as routers accept and handle packets only if the destination MAC address in the packet is the same as the MAC address of the Layer 3 interface on which the packet is received. To interoperate with these devices, connected devices must also be able to rewrite the destination MAC address of an incoming packet. An OpenFlow controller can configure on devices that supports OpenFlow to rewrite the destination MAC address of an incoming packet.
