Route filtering

Route filtering is like sorting candies into different bowls. You put the red candies in one bowl, the blue candies in another bowl, and so on.

In the same way, route filtering is like putting different kinds of internet traffic into different paths or routes. This is done to make sure that the right kind of traffic goes to the right place and that everything works smoothly.

For example, imagine you have a big office building with lots of computers and servers. Some computers are used for email, some for browsing the internet, and others for important things like online transactions.

To make sure that each kind of traffic goes to the right server or computer, you use route filtering. You set up rules to tell the internet where each kind of traffic should go. For example, you might say that all email traffic should go to one server, while browsing traffic should go to another.

This helps prevent congestion or delays on the network, and makes sure that everything runs efficiently. Just like how sorting candies into separate bowls makes it easier to find the one you want, route filtering helps make sure that internet traffic gets where it needs to go.
