route-map的配置

对于IGP协议,用prefix-list定义路由，通过Route-map调用进行路由过滤。

对于BGP协议，用Prefix-List,As-Path List Community-list定义路由，再通过route-map进行调用•Network x.x.x.x x.x.x.x （对IGP路由进行汇总宣告此路由必须在路由表中有一个精确匹配的路由）还须要配置一条该汇总静态路由指向空端口属于虚假汇总，需要创建指向null 0的静态路由
•Aggregate x.x.x.x x.x.x.x (summary-only) (as-set)
真正的汇总，汇总BGP表中的路由，具体路由可以通过summary-only抑制as-set可以设置被汇总具体路由的AS编号
