前言：
眼前咱们对“跨域怎么配置路由器”大体比较看重，大家都需要剖析一些“跨域怎么配置路由器”的相关文章。那么小编同时在网络上汇集了一些对于“跨域怎么配置路由器””的相关文章，希望我们能喜欢，我们一起来了解一下吧！1.1.1 关于本实验
本实验主要介绍了跨域VPN Option-C方案一的配置方法。
1.1.2 实验目的
掌握Option-C方案一原理，掌握其配置思路和方法。
1.1.3 实验组网介绍
图1-1 跨域VPN Option-C方案一配置实验拓扑图
1.1.4 实验规划
如上图所示，共分为4个AS，PE1、RR1、P1和ASBR1属于AS100，PE2、RR2、P2和ASBR2属于AS200。CE1和CE2属于同一个VPN，CE1通过AS100的PE1接入，CE2通过AS200的PE2接入，每台路由器的IP地址规划详见拓扑图。
