Internet Protocol Routing

IP Routing is the set of protocols  which resolves the path of data from the source to its destination.
One  program to simulate IP routing is the Scalable Cisco IOS Simulator for Virtual Machine.

In  this exercise, we need to connect 3 nodes or computers and determine if they can communicate which each other. After the exercise, the computer should have the capability of communicating with each other using the command 'ping'.


Here are the steps for solving the problem:

 network 1 will be 192.168.0.1
 network 2 will be 192.168.1.1
 network 3 will be 192.168.2.1

1. Make sure that you have a Network  Simulator installed on your machine. Launch the simulator to start.
2. We need 3 nodes/ host so we are going to click the computer monitor icon and generate 3 hosts by clicking and dragging it to the workspace.
3. Each computer/host needs identity so that it can be identified by other hosts. To do this, we should configure the IP  address, subnet mask and gateway of each host.
4. Configuration can be:
      Host 1 : 192.168.0.101, 255.255.255.0, 192.168.0.1
      Host 2:  192.168.1.101, 255.255.255.0, 192.168.1.1
      Host 3:  192.168.2.101, 255.255.255.0, 192.168.2.1

5. Next, we should generate 3 routers for each network and connect each host to  their respective network through the network interface ( eth#).

6 For the networks to communicate with each other,we will generate a switch. Connect the routers to the switch.

7. To test the network, open the terminal of a host and ping another host.

In this exercise, I have learned that for computers to interact with each other, IP, subnet, gateway should be configured. I have also learned that networks can communicate by connecting them using a switch.
