Question: In which layer of the OSI model does IP routing operate?

Options:

Correct Answer: Network layer

Solution:

IP routing operates at the Network layer (Layer 3) of the OSI model.

In which layer of the OSI model does IP routing operate?

In which layer of the OSI model does IP routing operate?

Step 1: Understand what the OSI model is. It is a framework that helps us understand how different networking protocols work together.
Step 2: Learn about the layers of the OSI model. There are 7 layers, each with its own function.
Step 3: Identify the layers of the OSI model: Layer 1 is Physical, Layer 2 is Data Link, Layer 3 is Network, Layer 4 is Transport, Layer 5 is Session, Layer 6 is Presentation, and Layer 7 is Application.
Step 4: Focus on Layer 3, which is the Network layer. This layer is responsible for routing data between devices on different networks.
Step 5: Recognize that IP (Internet Protocol) is a protocol used for routing data at the Network layer.
Step 6: Conclude that since IP routing is about directing data packets from one network to another, it operates at the Network layer (Layer 3) of the OSI model.

OSI Model Layers – Understanding the seven layers of the OSI model and their functions.
Network Layer Functions – Knowledge of the responsibilities of the Network layer, including routing and addressing.
