摘要： One embodiment of the present invention provides a switch. The switch includes a storage device, one or more line cards, and a control card. A respective line card includes one or more ports and forwarding hardware. The control card determines routing and forwarding tables for the switch, and comprises processing circuitry and a management module. The management module manage a tunnel or virtual network at the switch. During operation, the control card determine an event associated with layer-2 operations of the switch. The control card refrains from notifying the management module regarding the event and notifies a first line card in the one or more line cards regarding the event. The first line card then updates a layer-3 forwarding entry in the corresponding forwarding hardware based on the notification.

摘要： One embodiment of the present invention provides a switch. The switch includes a storage device, a rule management module, an inner packet module, and a packet processor. During operation, the rule management module obtains a rule associated with a data flow within tunnel encapsulation of a tunnel. This rule indicates how the flow is to be processed at the switch. The rule management module then applies an initial rule to a respective line card of the switch. The initial rule is derived from a virtual network identifier, which is associated with the tunnel, of the obtained rule. The inner packet module determines that a first inner packet, which is encapsulated with a first encapsulation header, belongs to the flow without decapsulating the first encapsulation header. The rule management module applies the obtained rule to a line card associated with an ingress port of the encapsulated first inner packet.
摘要翻译：本发明的一个实施例提供了一种开关。交换机包括存储设备，规则管理模块，内部分组模块和分组处理器。在操作期间，规则管理模块获得与隧道的隧道封装内的数据流相关联的规则。此规则指示如何在交换机上处理流。规则管理模块然后将初始规则应用于交换机的相应线路卡。初始规则是从所获得的规则的与隧道相关联的虚拟网络标识符中导出的。内部分组模块确定用第一封装报头封装的第一内部分组属于该流，而不解封第一封装报头。规则管理模块将获得的规则应用于与封装的第一内部分组的入口端口相关联的线路卡。
