[align=left]C 12.1.1.0 is directly connected, Serial1/2 [/align]
[align=left]总结：STUB选项[/align]
[align=left]receive-only: 防止STUB路由器发送路由更新[/align]
connected: 允许STUB路由器发送直连路由信息
[align=left]static : 允许STUB路由器发送重发布静态的路由[/align]
[align=left]summary :允许STUB路由器发送汇总路由信息[/align]
[align=left]通过以上测试我们发现，要让R1学习到R2发布过来的重发布路由，以及汇总路由。必须要加上如下参数[/align]
[align=left]R2 [/align]
[align=left]eigrp stub connected static summary [/align]
Note:默认STUB选项后面是connected 和summary
