What is STP and how does it work? Spanning Tree Protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when ...

Finding the minimum spanning tree is one of the fundamental algorithms and it is important in computer science and practical programming. We take a look at the theory and the practice. Before we get ...

Those who had an opinion last week were split evenly: CCNA labs need either 2 or 3 switches, and CCNP labs need either 3 or 4. But why? We saw a few opinions floating around the blog last week, but ...

An algorithm that runs in network bridges and switches to prevent loops, in which packets keep going around in circles. In a small network with one or two switches, the spanning tree protocol (STP) ...
