Uso de rutas estáticas

What are routes and how are they configured?

Talking about networks and telecommunications may seem complicated, but let's break it down to better understand how routes work and are configured in a network. To begin with, it is important to know that routes are configured in devices called routers. These devices are responsible for receiving data packets and routing them through the network to their destination.

How do routers work?

Routers make crucial decisions about where to send data packets based on source and destination addresses. This process includes identifying the packet's input port and deciding which of the other ports to send it through to reach its destination.

What are static routes?

Static routes are a fundamental, manual way of configuring a router's view of the entire network topology to which it is connected. Here we detail the process step by step to have a better understanding:

• Manual Configuration: In static routes, you must manually configure each connection in the network topology. That is, you manually specify to the router all the networks to which it will be connected and the routes to reach the networks that are not directly connected.

• Practical Example: Let's think of a city. If you are in a private house, there are streets close to you, but there will also be others that are further away. To reach another city, you could use a highway that connects your city with the destination city. When driving, you need to know the location of that highway and the streets leading to it. Similarly, in a static route, the router needs to know all the "streets" and "highways" in the network.

Advantages and disadvantages of static routes

Like any technology, static routes have their pros and cons, which are summarized below:

• Advantages:

1. Simplicity: They are easy to understand and configure in small topologies.
2. Stability: They do not change unless manually reconfigured, which can reduce variability in network operation.

• Disadvantages:

1. Scalability: They require considerable effort to configure in large topologies, being impractical.
2. Maintenance: Every change in the network requires a manual update of the routes.

What comes after static routes?

Although static routes are useful in small networks, they become impractical as the network topology grows in size and complexity. This is why, in larger networks, more advanced and efficient methods are used, which we will see later.

Remember, although this topic may seem technical, understanding the fundamentals provides a solid foundation for how information flows in our everyday networks.
