This blog post is the first in a series covering Performance Routing (PfR) formerly known as Optimized Edge Routing (OER) that I will be publishing over the coming weeks.  I decided to cover PfR in a series of blog posts contrary to a single post as PfR is a very powerful and useful feature that leverages the power of Cisco’s IOS but at the same time PfR is potentially very complicated and often confusing feature to configure and troubleshoot.  Trying to cover PfR in a single blog post would be the equivalent of trying to cover OSPF in a single blog post.  In fact if you compare the IOS 12.4T OSPF Configuration Guide against the Optimized Edge Routing (OER) Configuration Guide you will notice that OER documentation is nearly 35% larger.

And somewhere along the way, I realised I was doing most of it on my own. The late nights started adding up. Long calls with suppliers making sure the bill of materials was right, checking the solution actually held together end to end, always that nagging feeling that something had been missed somewhere. It just kept going. And then something shifted in me. It's hard to describe. I'd never experienced anything like it before - burnout, anxiety, call it what you want - but it hit me in a way I really wasn't prepared for. I've always been someone who...
