摘要： A method and system for automatically generating a route distinguisher for a virtual private network are disclosed. The method includes receiving a virtual private network name and rejecting the virtual private network name if the name comprises a number of bytes greater than a predefined limit. If the virtual private network name is less than the predefined limit, an algorithm is applied to automatically convert the virtual private network name to a route distinguisher for the virtual private network.

摘要： A method, apparatus and computer program product for routing data within a packet-switched network using a PW wherein the PW is terminated directly on the layer-3 routing device such that certain services and applications can be utilized is presented. The method, apparatus and computer program product receives an encapsulated layer-2 Protocol Data Unit (PDU) from a pseudowire emulating a service. The encapsulation is removed from the encapsulated layer-2 PDU and a layer-2 circuit associated with the pseudowire is terminated. The circuit is treated as an interface and the PDU is forwarded based on upper layer protocol information within the PDU.

摘要： A method and computer program product for providing autonomous system interconnect for a first peer device is presented. The method includes producing routing information at a first peer. Next, the first peer device provides a context identifier in the routing information. A context authenticator is also provided in the routing information at the first peer. The first peer then advertises this routing information to a second peer. The first peer only accepts messages from the second peer which include the context identifier and the context authenticator.

摘要： A mechanism for ASBRs to identify the originating node, or router, in an LSP conversant autonomous system (AS), such as an MPLS VPN environment, maintains the identity of the originating node and successive nodes in subsequent autonomous systems along the path to the node to be pinged. The identity of the transporting nodes is stored in a stack or other object associated with the ping request (ping), such that the pinged node may employ the stored identity as a set of return path routing information. Successive ASBRs store their identity on the stack, in an ordered manner, along the path to the destination. Upon reaching the destination (ping) node, the destination node employs the identity of the first node on the stack to send the acknowledgment, or ping response. Each successive ASBR, therefore, pops (retrieves) the next node identity from the stack and redirects (sends) the ping response to the retrieved node.
摘要翻译：用于识别LSP熟练自治系统（AS）（例如MPLS VPN环境）中的始发节点或路由器的机制在沿着节点的路径的后续自治系统中维护始发节点和连续节点的身份要ping 传输节点的身份存储在与ping请求（ping）相关联的堆栈或其他对象中，使得被ping过的节点可以将所存储的身份用作一组返回路径路由信息。连续的ASBR将按照有序的方式将其身份存储在堆栈中，沿着目的地的路径。在到达目的地（ping）节点时，目的地节点采用栈上的第一个节点的身份来发送确认或ping响应。因此，每个连续的ASBR从堆栈中弹出（检索）下一个节点标识，并将ping响应重定向（发送）到检索到的节点。
