CISCO路由器ISIS和BGP混合组网实例<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

本实例共有5台7200路由器，分别为R1、R2、R3、R4、R5，R1、R2和R3组成AS100自治域，R5为AS10自治域，R4为AS20自治域，在AS100自治域内，启用了ISIS动态路由协议，R1为R3和R2的反射器，此例为典型的三家ISP互连的骨干路由器配置，在本例中，我们也可将AS10和AS20像AS100那样做得大一点，在内部也启用ISIS等态路由协议，OSPF的例子就不讲了，也ISIS很像。本实例的目的是三个自治域的所有IP地址都能互相PING通。
借此机会，感谢小凡的CISCO路由模拟器，本实例就是在它的帮助下完成的，我的电脑是PIII <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />1G，512M MEM，运行5台7200路由器很不错，就是在查看配置文件内容是有点慢。
一、网络拓扑图
<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />
二、各路由器配置
1、  R1配置和测试
