關於cisco指令
 

各位大大好，我是用cisco原廠提供的Packet Tracer5.1的環境來模擬設備，我現在有三顆Router要互相連結，Router1與Router2起來了，但Router2到Router3卻起不來，我將圖擷取下來了，麻煩知道的大大幫我看一下，是那邊有問題，謝謝。

圖實在太小了，能不能直接貼上來呢？
我眼力看不清楚勒

ROUTER1
Router>en
Router#conf t
Router(config)#host Router1
Router1(config)#enable password cisco
Router1(config)#enable secret cisco
Router1(config)#line vty 0 4
Router1(config-line)#password cisco
Router1(config-line)#login
Router1(config-line)#exit
Router1(config)#service password-encryption
Router1(config)#int s 1/0
Router1(config-if)#ip add 202.119.249.1 255.255.255.0
Router1(config-if)#clock rate 64000
Router1(config-if)#no shutdown

ROUTER2
Router>en
Router#conf t
Router(config)#host Router2
Router2(config)#enable password cisco
Router2(config)#enable secret cisco
Router2(config)#line vty 0 4
Router2(config-line)#password cisco
Router2(config-line)#login
Router2(config-line)#exit
Router2(config)#service password-encryption
Router2(config)#int s 1/0
Router2(config-if)#ip add 202.119.249.2 255.255.255.0
Router2(config-if)#clock rate 64000
Router2(config-if)#no shutdown
Router2(config-if)#exit
Router2(config)#int s1/1
Router2(config-if)#ip add 202.119.249.4 255.255.255.0
% 202.119.249.0 overlaps with Serial1/0

ROUTER3
Router>en
Router#conf t
Router(config)#host Router3
Router3(config)#enable password cisco
Router3(config)#enable secret cisco
Router3(config)#line vty 0 4
Router3(config-line)#password cisco
Router3(config-line)#login
Router3(config-line)#exit
Router3(config)#service password-encryption
Router3(config)#int s 1/0
Router3(config-if)#ip add 202.119.249.3 255.255.255.0
Router3(config-if)#clock rate 64000
Router3(config-if)#no shutdown

Router1的serial1/0接到Router2的serial1/0，Router2的serial1/1接到
Router3的serial1/0
謝謝。

問題解決了,Router1的s1/0和Router2的s1/0與Router2的s1/1與Router3的s1/0應不同網段,謝謝。
