Abstract: 本申请实施例公开了一种路由生成方法,第一网络节点可以获得多条路由,该多条路由中包括到达第二网络节点的路由。第一网络节点获取到多条路由之后,可以确定到达第二网络节点的路由不参与路由聚合。进一步地,第一网络节点对该多条路由中除到达第二网络节点的路由之外的其它路由进行路由聚合,生成聚合路由。而后,第一网络节点将聚合路由和到达第二网络节点的路由向第三网络节点发送。利用本方案,由于到达第二网络节点的路由未被聚合,因此,可以利用BFD技术检测到达第二网络节点的路由的可达性,并在到达第二网络节点的路由不可达时,迅速将数据切换至到达第二网络节点的路由的ECMP等价路由上转发,或者进行FRR切换,避免数据长时间丢包。

Abstract: Some embodiments of the invention provide novel methods for providing a stateful service at a network edge device (e.g., an NSX edge) that has a plurality of north-facing interfaces (e.g., interfaces to an external network) and a plurality of corresponding south-facing interfaces (e.g., interfaces to a logical network). In some embodiments, the network edge device receives data messages from a first gateway device from a logical network, provides the stateful network service to the data message, and forwards the data message towards the destination through a corresponding interface connected to a physical network.
