默认路由实验

拓扑图：

基本配置

ROUTER1：

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname r1
r1(config)#enable secret ccna
r1(config)#interface fastEthernet 0/0
r1(config-if)#ip add 10.1.1.1 255.0.0.0
r1(config-if)#no shutdown

r1(config-if)#line vty 0 4
r1(config-line)#login
r1(config-line)#password ccna
r1(config-line)#exit
r1(config)#interface serial 0/0
r1(config-if)#ip add 192.168.10.1 255.255.255.0
r1(config-if)#no shutdown

ROUTER2：

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname r2

r2(config)#enable secret ccnp
r2(config)#interface fastEthernet 0/0
r2(config-if)#ip address 172.168.1.1 255.255.0.0
r2(config-if)#no shutdown

r2(config-if)#line vty 0 4
r2(config-line)#login
r2(config-line)#password ccnp
r2(config-line)#exit
r2(config)#interface serial 0/0

r2(config-if)#ip address 192.168.10.2 255.255.255.0
r2(config-if)#no shutdown

r2(config-if)#exit
r2(config)#interface serial 0/1

r2(config-if)#ip address 192.168.20.1 255.255.255.0
r2(config-if)#no shutdown
r2(config-if)#clock rate 56000
r2(config-if)#exit

ROUTER3：

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname r3
r3(config)#enable secret ccie
r3(config)#interface fastEthernet 0/0
r3(config-if)#ip address 192.168.1.1 255.255.255.0
r3(config-if)#no shutdown

r3(config-if)#line vty 0 4
r3(config-line)#login
r3(config-line)#password ccie
r3(config-line)#exit
r3(config)#interface serial 0/0
r3(config-if)#ip address 192.168.20.2 255.255.255.0
r3(config-if)#no shutdown

r3(config-if)#exit

配置默认路由：

r1(config)# ip route 0.0.0.0 0.0.0.0 192.168.10.2

r2(config)#ip route 10.0.0.0 255.0.0.0 192.168.10.1

r2(config)#ip route 192.168.1.0 255.255.255.0 192.168.20.2

r3(config)# ip route 0.0.0.0 0.0.0.0 192.168.20.1

验证默认路由

r1#show ip route

C 10.0.0.0/8 is directly connected, FastEthernet0/0

C 192.168.10.0/24 is directly connected, Serial0/0

S* 0.0.0.0/0 [1/0] via 192.168.10.2

r2#show ip route
