Whether it’s configuring a small local network or managing large enterprise infrastructures, mastering network addressing is essential for effective network management and troubleshooting.

Routing Protocols Explained in Chapter 7

Routing protocols are essential for determining the most efficient path for data to travel across a network. These protocols enable routers to exchange information, learn about network topologies, and adapt to changes in the network, ensuring that data reaches its destination in the fastest and most reliable way possible. Understanding how these protocols function is crucial for maintaining network efficiency and stability.

Different routing protocols use varying methods to select the best path for data transmission. The two main categories are interior gateway protocols (IGPs), which operate within a single network, and exterior gateway protocols (EGPs), which are used to route data between different networks. Each protocol has its own set of rules and advantages depending on the network’s size, complexity, and requirements.

Key routing protocols commonly discussed include:

• RIP (Routing Information Protocol): A distance-vector protocol that uses hop count as its metric to determine the best path.
