Abstract: In some embodiments, a switch module is configured to receive from a first edge device a multicast data unit having a VLAN identifier. The switch module is configured to select a set of port modules based on the VLAN identifier. The switch module is configured to define an unmodified instance of the multicast data unit for each port module from the set of port modules. The switch module is configured to send the unmodified instance of the multicast data unit to each port module from the set of port modules, such that each port module applies a filter to the received instance of the multicast data unit to restrict that received instance of the multicast data unit from being sent to a second edge device via that port module if the second edge device is associated with a VLAN domain different than a VLAN domain of the first edge device.

Abstract translation: 在一些实施例中，交换机模块被配置为从第一边缘设备接收具有VLAN标识符的多播数据单元。 交换机模块配置为根据VLAN标识选择一组端口模块。 交换机模块被配置为从该组端口模块为每个端口模块定义组播数据单元的未修改实例。 所述交换机模块被配置为从所述端口模块集合向所述端口模块发送所述多播数据单元的未修改实例，使得每个端口模块向接收到的所述多播数据单元的实例应用过滤器，以限制所接收的所述实例 多播数据单元如果第二边缘设备与不同于第一边缘设备的VLAN域的VLAN域相关联，则经由该端口模块被发送到第二边缘设备。
