Abstract: According to one aspect, a control entity (such as a policy server) in communication with a plurality of border routers in a network, generates failover entries for one or more traffic flows. Each failover entry specifies a backup path to be used by a border router when the border router determines that a wide area network interface of the border router has failed. The control entity sends the failover entries to each of the border routers. A border router operating in a network stores failover entries for one or more traffic flows. For packets received at the border router either from a local area network interface or via a tunnel from another border router, when the border router detects that the wide area network interface has failed, the border router determines how to handle the packets based on the stored failover entries.

Abstract translation: 根据一个方面，与网络中的多个边界路由器通信的控制实体（例如策略服务器）为一个或多个业务流生成故障切换条目。 每个故障转移条目指定当边界路由器确定边界路由器的广域网接口出现故障时要由边界路由器使用的备份路径。 控制实体将故障转移条目发送到每个边界路由器。 在网络中运行的边界路由器存储一个或多个流量流的故障转移条目。 对于从边界路由器接收的分组，从局域网接口或通过另一边界路由器的隧道接收到的报文，当边界路由器检测到广域网接口出现故障时，边界路由器根据所存储的路由器确定如何处理报文 故障切换条目。
