🌐 Routing Basics: Connecting Different Networks Together

How do data packets travel across completely separate networks or between different VLANs when local switches can no longer reach them? Through Routing.

Here are the key points:

🔹 1. What is Routing?

The process of moving data packets from one independent network to another.

While switches handle communication within a single local network, routers are required to cross boundaries and deliver data to external subnets or networks.

🔹 2. Static vs. Dynamic Routing

Static Routing: Manually configured by a network administrator. Great for small, stable networks, but difficult to scale.

Dynamic Routing: Routers automatically share information and discover paths using protocols like OSPF or EIGRP, adapting on the fly when network changes occur.
