ccna 静态路由实验
题外话：
实验参照电子工业出版社的ccna认证指南640-802，配置好了始终ping测试不通，物理上连接不可达（Pinging 12.1.1.1 with 32 bytes of data:
Reply from 192.168.1.1: Destination host unreachable.）后来上网查了下，原来是串口没有配置时钟频率......
实验在cisco packet tracer5.2下做的
拓扑图：
1.配置ip地址
pc上如图配置
R1上
en
conf t
int f0/0
ip add 192.168.1.1 255.255.255.0
no shut
int s0/1
clock rate 128000
ip add 12.1.1.1 255.255.255.0
no shut
exit
write
R2上
en
conf t
int s0/0
clock rate 128000
ip add 12.1.1.2 255.255.255.0
no shut
int s0/1
clock rate 128000
ip add 23.1.1.2 255.255.255.0
no shut
exit
write
R3上
en
conf t
int s0/0
clock rate 128000
ip add 23.1.1.3 255.255.255.0
no shut
int lo0
ip add 3.3.3.3 255.255.255.0
no shut
exit
write
测试用pc ping各个接口
PC>ping 12.1.1.2
Pinging 12.1.1.2 with 32 bytes of data:
Reply from 12.1.1.2: bytes=32 time=95ms TTL=254
PC>ping 23.1.1.2
Pinging 23.1.1.2 with 32 bytes of data:
Reply from 192.168.1.1: Destination host unreachable.
PC>ping 3.3.3.3
Pinging 3.3.3.3 with 32 bytes of data:
Reply from 192.168.1.1: Destination host unreachable.
2.配置路由
R1上
en
conf t
ip route 3.3.3.0 255.255.255.0 12.1.1.2
ip route 23.1.1.0 255.255.255.0 12.1.1.2
exit
write
R2上
en
conf t
ip route 3.3.3.0 255.255.255.0 23.1.1.3
ip route 192.168.1.0 255.255.255.0 12.1.1.1
exit
write
R3上
en
conf t
ip route 192.168.1.0 255.255.255.0 23.1.1.2
ip route 12.1.1.0 255.255.255.0 23.1.1.2
exit
write
测试在pc上ping各个地址均能ping通
