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.

By default, Systems can ping to each other in the same network (LAN) if there are no rules specified in a security group.
Here, I set up the Environment in such a way as follows:
- System A can ping to System B and System C
- System B and System C ping to System A
- System B can’t ping to System C and vice-versa
> Assigning manually IP to System A and then add in the routing table:-
# ifconfig enp0s3 192.168.43.1/24
# route add -net 192.168.43.0/30 enp0s3
>Similary, In-System B:-
# ifconfig enp0s8 192.168.43.2/24
# route add -net 192.168.43.0/31 enp0s8
>Similary, In-System C:-
# ifconfig enp0s8 192.168.43.3/24
# route add -net 192.168.43.0/31 enp0s8
