Abstract: A communications method and apparatus for a Virtual Extensible Local Area Network (VXLAN), where the method includes receiving, by a first layer-3 gateway device, host routing information from a second layer-3 gateway device, where the host routing information includes an Internet Protocol (IP) address of a first host, a media access control (MAC) address of the first host, and a VXLAN tunnel end point (VTEP) identifier of a next hop of the first layer-3 gateway device and that exists when the first layer-3 gateway device sends information to the first host, and forwarding, by the first layer-3 gateway device, a traffic packet destined for the first host or acting, by the first layer-3 gateway device, as an Address Resolution Protocol (ARP) proxy for the first host, based on the host routing information. Hence, traffic waste can be reduced.

Abstract: Embodiments include a load balancing method used to implement load balancing in a network. The method is performed by a first PE device, includes: obtaining a first device identifier of the first PE device, and obtaining a target ESI that is of a target NVE device and is corresponding to the first device identifier and a VN ID that is of a target VN accessed by the target NVE device and is corresponding to the first device identifier; receiving a message from a second PE device, where the message carries a second device identifier of the second PE device, and the target ESI and the VN ID of the target VN that are corresponding to the second device identifier; and determining whether the first PE device is a DF of the target NVE device in the target VN.
