帧中继-实验（第三篇）

帧中继的两个实验：点到点、点到多点

1、【点到点】

拓扑如下：

实验步骤

帧中继交换机设置

r1>r2 DLCI :102
r1>r3 DLCI :103

注意：r2和r3之间是没有PVC的。

r1上

interface Serial0/0/0
 no ip address
 encapsulation frame-relay
!
interface Serial0/0/0.2 point-to-point
 ip address 10.0.0.1 255.255.255.0

测试：pc0去ping pc1和pc2

pc1去ping pc2

2、【点到多点】

拓扑同上

r1>r2 DLCI :102    r2>r1 DLCI :201
r1>r3 DLCI :103    r3>r1 DLCI :301

测试：

R1的路由表：

R2的路由表：

R3的路由表：

PC0 ping PC1和PC2

PC1ping PC2

由于水平分割是不能ping通的！
