帧中继配置（使用tunnel）

守望天空

拓扑如图，暂时目的就是全网能ping通
使用 小凡模拟器
FR1 FR2 中间用tunnel

问题：R1和R2都能ping通自己，且都能ping通对方。但是不能ping通R3，R3也不能ping 通R1，R2

看这个输出应该是R3 有问题，可以自己也没有找到，找人帮忙看了，也没找到错误！

有点久没有配置FR的tunnel了，明天帮你看看，先休息了~

interface Tunnel0/ O' F$ M' K2 P. w$ A: j0 {& n
no ip address, |1 M# y& a3 R3 Y* g1 G( d
tunnel source Serial0/2* {) w" P) `5 F9 @

在做tunnel的时候，FR之间应该使用的是以太网链路。

而且，你R1、R2、R3上，不必要配时钟频率，帧中继交换机配就可以了。

做tunnel，应该用以太网链路。即两台FR，不能用串行接口相连。
