Welcome to the heart of networking; the routing protocols. We being our protocols series with the most simple and one of the originals: RIP, the Routing Information Protocol.

Networking 101: Understanding OSPF, Part 1

Open Shortest Path First is a robust link-state IGP. People use OSPF when they discover that RIP just isn’t going to work for their larger network, or when they need very fast convergence. This edition of Networking 101 will be a conceptual overview of OSPF, and the second part of OSPF coverage will delve a bit deeper into the protocol itself, as well as OSPF area configurations.

Networking 101: Understand the Rest of OSPF

The real nuts and bolts of everyone’s IGP of choice, OSPF, are a bit complex, but strangely satisfying. After understanding how it works, we’re left wondering, “what else do we need?” Make sure to review the first part of the OSPF pair before embarking on this potentially confusing journey.

Networking 101: Understand Multicast

Multicast has become a buzzword, more than once in history. IP multicast means that one sender is sending data to multiple recipients, but only sending a single copy. It’s very useful for steaming media, so let’s explore how this works.
