摘要： A network data packet routing apparatus with BGP is configured to soft reset an AFI or SAFI, so that forwarding on routes associated with the AFI or SAFI can continue even after an event or error. One approach involves establishing a Border Gateway Protocol (BGP) peering session between a first node and a second node in a packet-switched network; detecting a BGP condition requiring a reset of a BGP address family indicator (AFI) data structure or a sub-address family indicator (SAFI) data structure, wherein the BGP condition does not affect states of routes in the AFI or SAFI; preserving a BGP state and a forwarding state of the AFI or SAFI; and forwarding data on routes represented in the AFI or SAFI. Soft notification messaging and marking routes as stale facilitates the approach.

摘要： The protection of multi-segment pseudowires by utilizing pre-computed backup paths is disclosed herein. Disclosed embodiments include methods that establish at least one backup path for multi-segment pseudowires, the establishing being performed prior to detection of failure in the primary path. Upon detecting a path failure, the detected failure is signaled to the head-end, a pre-computed backup path is chosen, and the chosen backup path is signaled to the tail-end. In other disclosed embodiments, apparatus are configured to establish, prior to detection of failure in the primary path, at least one backup path for the multi-segment pseudowire. Networks can be configured to signal a detected failure to the head-end; choose a pre-computed backup path; and signal the backup path to the tail-end.

摘要： Implementation of a VPN service such as a VPLS (Virtual Private Local area network Service) is performed utilizing a two-stage process. Two-stage process involves providing notification of whether a PE (Provider Edge) router in a label-switching network has VPLS capability. Notification can include broadcasting a message from a PE router to remote PE routers in the label-switching network to indicate whether the broadcasting PE router is VPLS enabled. A second stage of the two-stage process involves, based on receiving a notification that a PE router is VPLS enabled, generating a query message to discover a set of VPLS instances to which the broadcasting PE router belongs. A given PE router generating the query message can identify other PE routers in the label-switching network associated with the same VPLS for purposes of setting up the VPLS in the label-switching network.
摘要翻译：使用两阶段过程来执行诸如VPLS（虚拟专用局域网服务）之类的VPN服务的实现。两阶段过程包括提供标签交换网络中的PE（Provider Edge）路由器是否具有VPLS功能的通知。通知可以包括从PE路由器向标签交换网络中的远程PE路由器广播消息以指示广播PE路由器是否启用VPLS。两阶段过程的第二阶段包括基于接收到PE路由器启用VPLS的通知，生成查询消息以发现广播PE路由器所属的一组VPLS实例。生成查询消息的给定PE路由器可以标识与相同VPLS相关联的标签交换网络中的其他PE路由器，用于在标签交换网络中建立VPLS。
