Network Topology Setup in such a way so that System A can ping to two Systems System B and System C but both these systems should not be ping 👨🏻💻

Task Description📄

🔰 14.1 Create a network Topology Setup in such a way so that System A can ping to two Systems System B and System C but both these systems should not be pinging each other without using any security rule e.g firewall etc .

LET'S START

Prerequisites

1. Install Virtual Box
2. Any virtual machine installed

Let's Start

1. For this task we require three virtual machines .
2. In each vm go to the Network setting and use "Host-only Adapter" in the "Attached to" field and save the settings.

3. Start the 3 vm's.

Ip address of the 3 vm's

System A ip address: 192.168.1.2

System B ip address: 192.168.1.1

System C ip address: 192.168.1.4        

4. Below are the pictures showing the ip address and the netmask of System A, B, C respectively.

We configure the system A with "/29" as the CIDR.

Output of the ifconfig command

For System B

We configure it with "/30" as CIDR

Output of the "ifconfig" command

For System C

We configure the system C with /30 as CIDR

Output of the ifconfig command

Now we have to add the rules in the routing table

1. For System A

• Routing table rule

• Rule created in the routing table

2. For System B

• Routing table rule

• Rule created in the routing table

3. For System C

• Routing table rule

• Rule created in the routing table

5. Now we have created the environment let's ping now.

• From system A ping to B

• Now ping from system A to C

In the above pictures we can see System A is able to ping to System B and System C.

• Now try to ping to System C from System B

We see that it's not able to ping to System C.

• Now try to ping to System B from System C

We can see that the "Destination Host Unreachable" is coming up. This shows that the System C is not able to ping to System B.

Thank you.
