Abstract
In a method and an apparatus provided for implementing communication between virtual machines, a first switch receives an ARP response from an SDN controller, where the ARP response carries a MAC address of a destination gateway; the first switch acquires, according to the MAC address of the destination gateway, VTEP information corresponding to the MAC address of the destination gateway, where a router corresponding to the VTEP information is located in a first data center; and the first switch sends, according to the VTEP information, an IP packet to the router corresponding to the VTEP information, so that the router corresponding to the VTEP information sends the IP packet to a second virtual machine through a tunnel between the router and a second switch.
