static routing configuration

Now lets see the configuration of above LAB :

Router>enable

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname R1

R1(config)#int fa0/0

R1(config-if)#ip address 1.0.0.1 255.0.0.0

R1(config-if)#no shut

R1(config-if)#exit

R1(config)#int fa0/1

R1(config-if)#ip address 2.0.0.1 255.0.0.0

R1(config-if)#no shut

Router>en

Router#config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname R2

R2(config)#int fa0/0

R2(config-if)#ip address 3.0.0.1 255.0.0.0

R2(config-if)#no shut

R2(config-if)#exit

R2(config)#int fa0/1

R2(config-if)#ip address 2.0.0.2 255.0.0.0

R2(config-if)#no shut

R2(config-if)#exit

R2(config)#int eth0/0/0

R2(config-if)#ip address 4.0.0.1 255.0.0.0

R2(config-if)#no shut

Router>en

Router#config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname R3

R3(config)#int fa0/1

R3(config-if)#ip address 4.0.0.2 255.0.0.0

R3(config-if)#no shut

R3(config-if)#exit

R3(config)#int fa0/0

R3(config-if)#ip address 5.0.0.1 255.0.0.0

R3(config-if)#no shut

Now configure routers to route:

Configure static routing on Router R1:


R1(config)#ip route 3.0.0.0 255.0.0.0 2.0.0.2

R1(config)#ip route 5.0.0.0 255.0.0.0 2.0.0.2

R1(config)#ip route 4.0.0.0 255.0.0.0 2.0.0.2


Configure static routing on Router R2:


R2(config)#ip route 1.0.0.0 255.0.0.0 2.0.0.1

R2(config)#ip route 5.0.0.0 255.0.0.0 4.0.0.2

Configure static routing on Router R3:


R3(config)#ip route 3.0.0.0 255.0.0.0 4.0.0.1

R3(config)#ip route 2.0.0.0 255.0.0.0 4.0.0.1

R3(config)#ip route 1.0.0.0 255.0.0.0 4.0.0.1
