Abstract
Most of us have at one point struggled with understanding all the components of layer 3 architecture, such as: why do you need an IGP in addition to iBGP and eBGP? Anyone we want to join the industry will probably have to do so too, so why not try to come up with a simpler way to think about it? We'll sift through auction sites for vintage books and toys to find an unlikely template: the mix & match character with swappable head, torso and legs that can stand in for some of the more esoteric concepts. There'll be plenty of time for discussion and Q&A, so whether you have decades of BGP experience or are actively struggling with these concepts as we speak, join us as we decide if this model really does have legs. And who knows? We may find new perspectives or mentorship along the way.
