HCIP ----MPLS 实验

实验要求：

1.R1与R5MPLS  VPN

2.R6与R7MPLS VPN

3.R7可以访问R2/R3/R4的环回

实验草图：

 

实验拓扑图：

 IP规划如下：

环回

R1:192.168.1.0 /24

R2:    2.2.2.2 /24

R3:    3.3.3.3/24

R4:    4.4.4.4/24

R5:   192.168.4.1/24

R6:  192.168.1.1 /24

R7: 192.168.4.2/24

 

网段 

R2-R3     23.1.1.0   

R3-R4    34.1.1.0

R1-R2  192.168.2.0 

R2-R6 192.168.2.0

R4-R5   192.168.3.0

R4-R7 192.168.3.0

实验思路：

首先我们先把IP地址配置好

然后再将公网配置起来；先启动ospf

再使用mpls配置好，启用bgp，让R2与R4之间建立VPN的要求

在两端路由器中写缺少的静态路由即可，

而另外的是用协议进行双向重发布即可

以下便是配置的代码：

 总结：

经过这次实验，对于这个mpls的理解稍微清晰一点了，但是还是需要在对这个mpls的认识需要多加 练习才行。
