Establishment of static route

demand ：

The communication function is realized between the three computers directly connected by the three routers

analysis ： 

1.ip Division of address ---5 Different broadcast domains are divided into different IP Address .

2. Set up static routes in each router .

To configure ：

Router 1、2、3 The port of ip

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.1.2 24 
[r1-GigabitEthernet0/0/0]q
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 192.168.4.4 24

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 192.168.2.1 24 
[r2-GigabitEthernet0/0/0]q
[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 192.168.4.5 24
[r2-GigabitEthernet0/0/1]q
[r2]int g0/0/2
[r2-GigabitEthernet0/0/2]ip add 192.168.5.5 24

[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 192.168.3.1 24
[r3-GigabitEthernet0/0/0]q
[r3]int g0/0/2
[r3-GigabitEthernet0/0/2]ip add 192.168.5.6 24
