摘要： According to an example, virtual machine (VM) migration may include generating a redundant tunnel between a common edge device (ED) of a plurality of common EDs of a multi-site network (MSN) and a gateway ED of the MSN. A gateway media access control (MAC) address and a static route may be configured for forwarding an Internet protocol (IP) message between the common ED and the gateway ED using the redundant tunnel.

摘要： The present disclosure describes traffic forwarding in a network where Virtual Local Area Networks (VLANs) are deployed over geographically dispersed sites. The network comprises a first edge device (ED) at a first site and a second ED at a second site. In one example, the first ED receives traffic from a host device within the first site. The received traffic is to be forwarded to the second ED via a virtual link established between the first ED and second ED. The first ED determines whether a bandwidth required by the received traffic exceeds a bandwidth threshold negotiated between the first ED and second ED for the first ED to forward traffic to the second ED via the virtual link. If the negotiated bandwidth threshold is not exceeded, the received traffic is forwarded to the second ED via the virtual link. Otherwise, traffic with high priority is selected from the received traffic and forwarded to the second ED via the virtual link.
摘要翻译：本公开描述了在虚拟局域网（VLAN）部署在地理上分散的站点上的网络中的流量转发。网络包括在第一站点处的第一边缘设备（ED）和第二站点处的第二ED。在一个示例中，第一ED从第一站点内的主机设备接收流量。所接收的业务将经由在第一ED和第二ED之间建立的虚拟链路被转发到第二ED。第一ED确定所接收的流量所需的带宽是否超过第一ED和第二ED之间协商的带宽阈值，用于第一ED通过虚拟链路将业务转发到第二ED。如果未超过协商的带宽阈值，则所接收的流量经由虚拟链路被转发到第二ED。否则，从接收到的流量中选择具有高优先级的业务，并通过虚拟链路转发到第二ED。
