OER/PFR


This actually turns to be one of the most complicated topics that people who are currently preparing for the CCIE R&S lab must understand.

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.

CompTIA+

Sometimes you just need a good distraction, and I randomly got the urge to study for an exam;  something I haven't done in years. I decided to look into network security and started watching some CompTIA training videos, and...it was all a bit too familiar. Apparently the search continues.

The thing I didn't see coming

I keep forgetting I have this blog. But today felt like the right time to write something - something a bit more personal than usual. I want to talk about burnout. A while back I was deep in a very large infrastructure project. What started as a technical role slowly turned into something much broader - I found myself handling bits of legal, commercial negotiations, RFP work, supplier discussions. A lot of moving parts. 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...

I Miss My Old Friends

Today I had a long chat with an old friend. We hadn't spoken in a while, and somewhere in the conversation I opened up about the burnout (I call it a burnout, not sure what exactly it is)  I've been struggling with. What surprised me was that it wasn't unique — he'd been through something similar a few months ago. We ended up talking for over an hour. After we hung up, I realised something that's been sitting with me all evening: I miss my old friends. I miss those conversations. The kind where you'd talk about the future, about the plans, about how we were going to go out there and kick some serious ass (not physically, of course). Those conversations were stimulating . They left you walking away with more energy than you started with, not less. You felt sharper, more ambitious, more sure of who you were becoming. It's the kind of thing that's easy to take for granted when you have it — and impossible to replace when you don't. Life pulls people...
