请教：关于分区域OSPF 路由归纳的问题

unix_start

一级中心下挂16个二级中心，每个二级中心下有数十个网点，总共约有1000 多个网点。现在准备运行分区域的OSPF 协议，各个二级中心到一级中心之间是DDN 连接，属于区域0，各个二级中心各自为一个区域，同时要求二级中心上不能ping 通其他二级中心，也不能有其他二级中心的路由，各网点之间也不能互通。为了防止一级中心路由器上路由太多，我想使用路由归纳，使一级中心上的动态路由只有16个二级中心整段的路由。请问各位高手，这样做能实现吗？我搭了个模拟环境，发现一级中心的路由表上还是有网点的路由，我把配置和路由表贴出来，各位高手帮忙看看吧，急、急、急，在线等待，小弟先行谢过了！！

"各个二级中心到一级中心之间是DDN 连接，属于区域0"
按照你所说的，我想你不能设置AREA0，整个路由器中根本不能存在区域0，各个二级中心到一级中心分别用不同的AREA，但是不能是0，这样应该能达到你说的那种效果。。。

jacamar

地址设计挺混乱的，再规划一下；
你制定的summary 有问题，先不用或auto。

unix_start

问题解决了。是我的area id rang不对，而且我这里根本用不着summary，昨天看一天书，总算是明白了：）
因为是搭模拟环境，地址随便给的，而且我的意思也没说清楚，应该是把二级中心与一级中心相连的广域口划给area0，不过很感谢两位的帮助！！！
