Abstract: Many hybrid cloud topologies require virtual machines in a public cloud to use a router in a private cloud, even when the virtual machine is transmitting to another virtual machine in the public cloud. Routing data through an enterprise router on the private cloud via the internet is generally inefficient. This problem can be overcome by placing a router within the public cloud that mirrors much of the routing functionality of the enterprise router. A switch configured to intercept address resolution protocol (ARP) request for the enterprise router's address and fabricate a response using the MAC address of the router in the public cloud.

Abstract translation: 许多混合云拓扑需要公共云中的虚拟机在私有云中使用路由器，即使虚拟机正在传播到公共云中的另一个虚拟机。 通过互联网在私有云上通过企业路由器路由数据通常效率低下。 通过将路由器放置在公共云中来反映企业路由器的大部分路由功能，可以克服这个问题。 交换机被配置为拦截企业路由器地址的地址解析协议（ARP）请求，并使用公共云中的路由器的MAC地址来制定响应。
