Abstract: A method for assisting communication of a source host upon movement from a first Data center (DC) to a second DC is disclosed. The method includes identifying that the source host has moved from the first DC to the second DC, ensuring that packets identifying a source as the source host in the second DC are copied to a control plane network element, and, for a first destination host identified in a first packet copied to the control plane network element and identified as a host that is not in the second DC, updating an Address Resolution Protocol (ARP)/Neighbor Discovery Protocol (NDP) cache of the source host by sending, to the source host, a first ARP message/unsolicited neighbor advertisement specifying a Media Access Control (MAC) address of an edge router associated with the source host in the second DC as a destination MAC address for the first destination host.

Abstract translation: 公开了一种用于辅助源主机在从第一数据中心（DC）到第二DC的移动时的通信的方法。 该方法包括识别源主机已经从第一DC移动到第二DC，确保标识作为第二DC中的源主机的源的分组被复制到控制平面网元，并且对于识别出的第一目的地主机 在复制到控制平面网络元件并被识别为不在第二DC中的主机的第一分组中，通过将源主机的地址解析协议（ARP）/邻居发现协议（NDP））高速缓存发送到源 主机，第一ARP消息/未经请求的邻居通告，指定与第二DC中的源主机相关联的边缘路由器的媒体访问控制（MAC）地址作为第一目的地主机的目的地MAC地址。
