Playing with the Routing Table

๐น In this blog, we will be demonstrating the working of network topology. ๐น
๐ฐ 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.
At first all the systems can ping each other. Letโs verify that.
๐๐ป SystemA : Here, SystemA can ping to SystemB and SystemC
๐๐ป SystemB: Here, SystemB can ping to SystemA and SystemC
๐๐ป SystemC : Here, SystemC can also ping to SystemA and SystemB
So we can see all the systems are pinging each other.
Now lets check the routing table of System B and add the ip address of System C in reject list.
And do the same thing in System C with ip address of System B
๐น Now letโs ping :
๐๐ปSystemA : Here, SystemA can ping to SystemB and SystemC
๐๐ป SystemB: Here, SystemB can ping to SystemA but can not to SystemC
๐๐ปSystemC : Here, SystemC can ping to SystemA but unable to ping SystemB
So the desired task is completed.
