Building a custom network topology with python to demonstrate the L3 routing concept
The goal of the project is to build a custom network topology by using
3-L3 routers, two host machines with loopback addresses, and 4 subnets to demonstrate how L3 routing is done virtually with Mininet?
The drawback of L2 routing is that it works only when both the source and destination machine are present in the same subnet but by doing L3 routing we can solve the L2- routing problem and with the help of L3 routing we can send the packet from the source subnet to the destination subnet
Also, the drawback of Physical network infrastructure (hardware) require manual configuration and is not flexible enough to manage the network infrastructure and on the other hand, it is costly to operate
Thus, building custom network topology will help us manage the network efficiently and also increases the flexibility, security, ease to manage resources, greater control over the network, easy to adapt new use cases which emerges from the future
So, to build custom network topology a tool called Mininet(software-defined networking) is used with python
