Today I have met a technically challenging situation. I am working on a network that is not, on the surface, much different than many others. In this case, the problem is someone has, from the technology or geek standpoint, created a very complex network. We have OSPF, EIGRP, and static routes. OSPF and EIGRP redistributing each other, and each redistributing static routes, plus back door links.
Now this environment had some challenging networking issues to deal with. However I am thinking of my favorite philosophical law called Ockham's Razor. "It is a principle urging one to select among competing hypotheses that which makes the fewest assumptions and thereby offers the simplest explanation of the effect."
Sometimes the best solution is the simplest.
