Building a custom network topology with python to demonstrate the L2 routing concept

The goal of the project is to build a custom network topology by using Vlan, L2 switch, and two host machines to demonstrate how L2 routing is done practically?

Physical network infrastructure (hardware) require manual configuration and is not flexible enough to manage the network infrastructure 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
