On Friday, and for the fourth time, I took the CCIE R&S Written exam (350-001). For the third time, though, I failed. Let me tell you, I am absolutely devastated. I worked my buns off for the past few weeks, but Im obviously missing some important piece to put me over the top.

Back in the day, somebody decided that we all needed to have a Type of Service (ToS) field in the header of IP packets. Only God knows what this spawn of Satan wanted to do with it, but we’re stuck with it on the CCIE R&S exams. Can you tell I hate QoS?
Yes, I failed. I think it’s pretty typical when you’re at Cisco Live, stay out drinking and smoking cigars until 1am, then sit the exam at 8am. Considering the situation I put myself in, I wasn’t very optimistic about the exam. I figured maybe a 40% chance I would pass since I didn’t really even study. Are you sensing a theme of ill-preparedness and self-sabotage? Yeah, me, too.
The wife and I had a romantic day driving several hours to a small town to take Cisco exams. If this doesn’t get me some action, I don’t know what else to try.
I was studying via Google+ Hangout the other day with CJ and Rob, and one of the topics that came up was the idea of OSPFv2 advertising all loopbacks as 32-bit no matter what the configured mask is. I rarely use loopbacks outside of a lab and had no idea, so I set up a quick lab to see for myself. Sure enough! That’s exactly what I saw.
I’ve spent the last month or so with my nose down in a book and my mouse in a Google+ Hangout window studying my rear off for the CCIE R&S Written. Too bad I didn’t pass it.
