CCDE – BGP Convergence
Introduction This post will look at the steps involved in BGP convergence and how it interacts with IGP to converge.

RSTP synchronization – behind the scenes
RSTP synchronization is not widely understood and often oversimplified. This post describes how it really works in detail to give you the full picture.

STP convergence – MST
In the comments I received a wish to compare RPVST+ with MST. RPVST+ is Ciscos proprietary STP running one instance
