We will learn how to set 3 cisco router with ip-route comamnd
Look at this topologies :
PC0 : IP = 192.168.1.1, gateway = 192.168.1.10 /24
PC1 :IP = 192.168.1.2, gateway = 192.168.1.10 /24
PC2 :IP = 192.168.2.1, gateway = 192.168.2.10 /24
PC3 :IP = 192.168.2.2, gateway = 192.168.2.10 /24
PC4 :IP = 192.168.3.1, gateway = 192.168.3.10 /24
PC5 :IP = 192.168.3.2, gateway = 192.168.3.10 /24
PC6 :IP = 192.168.4.1, gateway = 192.168.4.10 /24
PC7 :IP = 192.168.4.2, gateway = 192.168.4.10 /24
PC8 :IP = 192.168.5.1, gateway = 192.168.5.10 /24
PC9 :IP = 192.168.5.2, gateway = 192.168.5.10 /24
PC10 :IP = 192.168.6.1, gateway = 192.168.6.10 /24
PC11 :IP = 192.168.6.2, gateway = 192.168.6.10 /24
Router0 to router1 : IP = 192.168.7.1 /24 (for router0 ) and 192.168.7.2 /24 (for router1 )
Router1 to router2 : IP = 192.168.8.1 /24 (for router1 ) and 192.168.8.2 /24 (for router2 )
Here standart configuration for Router0 :
Enable
Conf t
Host one
Int fa 0/0
Ip add 192.168.1.10 255.255.255.0
No shut
Exit
Int fa 1/0
Ip add 192.168.2.10 255.255.255.0
No shut
Exit
Int s 2/0
Ip add 192.168.7.1 255.255.255.0
Clock rate 56000
No shut
Exit
Exit
Copy run start
Here standart configuration for Router1 :
Enable
Conf t
Host two
Int fa 0/0
Ip add 192.168.3.10 255.255.255.0
No shut
Exit
Int fa 1/0
Ip add 192.168.4.10 255.255.255.0
No shut
Exit
Int s 2/0
Ip add 192.168.7.2 255.255.255.0
Clock rate 56000
No shut
Exit
Int s 3/0
Ip add 192.168.8.1 255.255.255.0
Clock rate 56000
No shut
Exit
Exit
Copy run start
Here standart configuration for Router2 :
Enable
Conf t
Host three
Int fa 0/0
Ip add 192.168.5.10 255.255.255.0
No shut
Exit
Int fa 1/0
Ip add 192.168.6.10 255.255.255.0
No shut
Exit
Int s 2/0
Ip add 192.168.8.2 255.255.255.0
Clock rate 56000
No shut
Exit
Exit
Copy run start
Now, we will use “IP ROUTE” command to make routing for routers.
We can use this common syntax :
IP ROUTE DESTINATION_NETWORK_ADDRESS SUBNET_MASK Through-IP
Router 0 : ( use IP Route command to go to network 192.168.3.0, 192.168.4.0, 192.168.5.0, and 192.168.6.0, NB: network 192.168.1.0 and 192.168.2.0 doesn’t need IP ROUTE command because it’s under Router0 network )
Here the command :
Enable
Conf t
Ip route 192.168.3.0 255.255.255.0 192.168.7.2
Ip route 192.168.4.0 255.255.255.0 192.168.7.2
Ip route 192.168.5.0 255.255.255.0 192.168.7.2
Ip route 192.168.6.0 255.255.255.0 192.168.7.2
Exit
Copy run start
Router 1 : ( use IP Route command to go to network 192.168.1.0, 192.168.2.0, 192.168.5.0, and 192.168.6.0, NB: network 192.168.3.0 and 192.168.4.0 doesn’t need IP ROUTE command because it’s under Router1 network )
Here the command :
Enable
Conf t
Ip route 192.168.1.0 255.255.255.0 192.168.7.1
Ip route 192.168.2.0 255.255.255.0 192.168.7.1
Ip route 192.168.5.0 255.255.255.0 192.168.8.2
Ip route 192.168.6.0 255.255.255.0 192.168.8.2
Exit
Copy run start
Router 2 : ( use IP Route command to go to network 192.168.1.0, 192.168.2.0, 192.168.3.0, and 192.168.4.0, NB: network 192.168.5.0 and 192.168.6.0 doesn’t need IP ROUTE command because it’s under Router2 network )
Here the command :
Enable
Conf t
Ip route 192.168.1.0 255.255.255.0 192.168.8.1
Ip route 192.168.2.0 255.255.255.0 192.168.8.1
Ip route 192.168.3.0 255.255.255.0 192.168.8.1
Ip route 192.168.4.0 255.255.255.0 192.168.8.1
Exit
Copy run start
Hope this tutorial usefull.
