摘要： A method and computer system for auto-routing of multi-hop pseudowires is presented. A first Provider Edge (PE) device receives an advertisement from a layer 2 (L2) capable network device, the advertisement including routing state for reaching the L2 device. A first Border Gateway Protocol (BGP) table is populated with the routing state for said L2 capable network device which is reachable by way of an address family reserved for L2 end point reachability information. The first PE device advertises the first BGP table information within a first Service Provider (SP) network such that a multi-hop Pseudowire is capable of being established which includes the L2 capable device.

摘要： A given router in the core of a label-switching network identifies a group of routers to receive common label binding information for later routing packets along respective paths through the label-switching network. One way to identify which of multiple routers to include as a member of the group to receive the same label information is to analyze egress policies associated with downstream routers in the label-switching network. Based on this analysis, the given router identifies group members as routers having a substantially same egress policy as each other. The given router then allocates memory resources to store a common set of label information to be distributed to each member in the group of routers having the same egress policy. After populating the memory resources with label information, the given router distributes a common set of label information to each router in the group of routers.
摘要翻译：标签交换网络的核心中的给定路由器标识一组路由器以接收公共标签绑定信息，以便随后通过标签交换网络沿相应路径路由分组。识别要包括作为组中成员以接收相同标签信息的多个路由器中的哪一个的一种方式是分析与标签交换网络中的下游路由器相关联的出口策略。基于该分析，给定路由器将组成员标识为具有彼此基本相同的出口策略的路由器。然后，给定路由器分配存储器资源来存储要分配给具有相同出口策略的路由器组中的每个成员的公共标签信息集合。在使用标签信息填充内存资源之后，给定的路由器将一组公共标签信息分配给路由器组中的每个路由器。

摘要： A method, apparatus and computer program product for performing inter-area summarization for edge-device addressing are presented. A network is established, the network including a first ABR, an ingress Provider Edge (PE) device in communication with the first ABR, a second ABR in communication with the first ABR, and an egress PE in communication with the second ABR. The first ABR and the second ABR are connected via an RFC3107 BGP session, as are the ingress PE and the first ABR as well as the egress PE and second ABR. The method further includes performing packet forwarding including PE address summarization through the network.

摘要： A method, apparatus and computer program product for providing convergence for a dual-homed site in a network is presented. An occurrence of a failure between a first Provider Edge (PE) device and a first Customer Edge (CE) device in communication with a dual-homed site is detected. A determination is made whether an alternate route exists for the dual-homed site in a routing table associated with the first PE device. When an alternate route exists then a routing entry associated with the first CE device in a routing table of said first PE device is kept from being deleted for a predetermined amount of time, the routing table is modified to reference the alternate route, the routing entry is rewritten to perform a POP and lookup in a VRF table of the first PE device, and the routing entry is deleted after the predetermined amount of time has elapsed.
