            neighbor fxp0.0;
            neighbor fxp1.0;
//个人理解：相当于在接口上启用rip
        }
    }
}

            from protocol static;
            then accept;
//相当于cisco的 redistribut static，重发布静态路由
        }

            then accept;
        }
        term 3 {
            from interface [ fxp0.0 fxp1.0 ];
            then accept;
//将在这些接口上收到的路由发布出去，包括这些接口的网络号
        }
    }
}
//juniper只要在接口上启用了了路由就默认接收路由，但是不会在接口上转发路由信息，需要定义转发策略，juniper默认使用ripv2，并且关闭自动总结。
