Connecting Two Routers with Serial cable:
Drag the two routers and two end devices to the workspace. Connect the two end devices to their respective routers through copper cross cables, and the two routers through the Serial DCE cable.
Now, first we need to turn on the ports and connect the end devices to their respective routers. For Router0, use the CLI and enter the following commands to turn up the FastEthernet0/0 port and assign an IP address to it. The PC0 is connected to that interface.
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Similarly, assign the IP address 192.168.2.1 to the FastEthernet0/0 interface of the Router1 which is connected to the PC1.
Now the devices are connected to their routers, but for communication, they need IP address. Assign some static IP address to the PC0 and PC1, such as 192.168.1.10 and 192.168.2.10 respectively.
Also, don't miss assigning the default gateways to the PC's IP config. For PC0 and PC1 it should be 192.168.1.1 and 192.168.2.1 respectively.
Check the connections by sending a ping message from the PCs to their routers. The two routers are connected but cannot with each other, we need to configure them.
Click on the Router0 and open its CLI. Use the following commands to assign an IP address and clock-rate to the serial interface:
Router(config)#interface Serial2/0
Router(config-if)#ip address 192.168.3.1 255.255.255.0
Router(config-if)#clock rate 64000
Router(config-if)#no shutdown
The clock rate is to be set for the serial connection. We have to set the clock rate only for the first router, and not for the second router. This is applicable in every network.
Similarly, assign IP address 192.168.4.1 to the connected serial interface of Router1 with the above commands, but don't set the clock rate.
Now all the connection lights have turned green. This means our network is ready.
But we cannot communicate, its too early. We need to configure the routes for the packet transmission. These routes can be configured from the CLI of the routers.
Enter the following commands to configure the dynamic routes for the routers. The entered routes/networks are the network addresses of all the different networks to which the router is connected. For Router0, the networks are 192.168.1.0 and 192.168.3.0:
Router(config)#router rip
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.3.0
Router(config-router)#exit
Similarly, for the Router1 the networks to be added are 192.168.2.0 and 192.168.4.0:
Router(config)#router rip
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.3.0
Router(config-router)#exit
Now when the networks are added to the route tables, the network is ready to communicate. Check the connectivity by sending test packets.
