Abstract: Aspects of the subject disclosure relate to methods for detecting a link failure between the first network device and a destination node, receiving a data packet addressed to the destination node, and rewriting encapsulation information of the first data packet. Subsequent to rewriting the encapsulation information of the first data packet, the first data packet is forwarded to a second network device (e.g., using updated address information in the packet header), wherein the second network device is paired with the first network device in the virtual port channel. In certain aspects, systems and computer readable media are also provided.

Abstract: Systems, methods, and non-transitory computer-readable storage media for translating source addresses in an overlay network. An access switch in an overlay network, such as a VXLAN, may receive an encapsulated packet from a tunnel endpoint in the overlay network. The encapsulated packet may originate from a host associated with the tunnel endpoint and be encapsulated at the tunnel endpoint with a first source tunnel endpoint address and a destination tunnel endpoint address. The access switch may replace the first source tunnel endpoint address in the encapsulated packet with a second source tunnel endpoint address of the access switch to yield a translated packet. The access switch may then transmit the translated packet towards the destination tunnel endpoint address.
Abstract translation: 用于翻译覆盖网络中的源地址的系统,方法和非暂时的计算机可读存储介质。 覆盖网络(例如VXLAN)中的接入交换机可以从覆盖网络中的隧道端点接收封装的分组。 封装的分组可以源自与隧道端点相关联的主机,并且在隧道端点处封装有第一源隧道端点地址和目的地隧道端点地址。 接入交换机可以用接入交换机的第二源隧道端点地址替换封装分组中的第一源隧道端点地址,以产生转换的分组。 然后,接入交换机可以将转换的分组发送到目的地隧道端点地址。
