Abstract: In some examples, a controller comprises one or more processors; a control unit configured to obtain, from a router in a first network, a route that specifies a next hop to an address prefix reachable by the first network; and a service chain unit configured to generate a modified route that specifies a service node as the next hop for the address prefix, wherein the service node is external to the first network, and wherein the control unit is further configured to send the modified route to a second network, the modified route marked with an import route target configured for a provider edge router of the second network so that traffic from the first network and destined for the second network is forwarded to the service node.

Abstract translation: 在一些示例中，控制器包括一个或多个处理器; 控制单元，被配置为从第一网络中的路由器获得指定下一跳到由所述第一网络可到达的地址前缀的路由; 以及服务链单元，其被配置为生成指定服务节点作为所述地址前缀的下一跳的修改路由，其中​​，所述服务节点在所述第一网络的外部，并且其中所述控制单元还被配置为将修改的路由发送到 第二网络，所述修改路由标记有为第二网络的提供商边缘路由器配置的导入路由目标，使得来自第一网络且去往第二网络的流量被转发到服务节点。
