CISCO路由器ISIS和BGP混合组网配置实例

CISCO 路由器 ISIS BGP 混合组网实例
本实例共有 5 7200 路由器,分别为 R1 R2 R3 R4 R5 R1 R2 R3 组成 AS100 自治域, R5 AS10 自治域, R4 AS20 自治域,在 AS100 自治域内,启用了 ISIS 动态路由协议, R1 R3 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 AS20 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 1G 512M MEM ,运行 5 7200 路由器很不错,就是在查看配置文件内容是有点慢。
