There are three ways to manipulate the interface cost in OSPF. One is very direct, one changes the presentation of the interface, and the other changes the calculations for every interface.
When you configure OSPF network statements, IOS orders them most-specific to least-specific then does a top-to-bottom match of the interfaces. It doesn’t matter which order you put them in, the configuration will always be ordered with the longest prefix matches first. Lab time!
I don’t think I’m going to give a direct review of Cisco Live US this year. The conference was great with lots of stuff going on, but I really can’t contribute any more than the vast library of other posts on the subject. What I will do, though, is give my take on where I think the conference is headed. These are all my thoughts and have little to do with reality in some cases.
Everything is in order for my trip to Cisco Live 2014 in San Francisco. Conference passes are purchased. Hotels are reserved. Flights are booked. It’s going to be a great event, and I can’t wait!
I was just reading through Bob’s blog post from today and wanted to give a rebuttal of sorts. In summary, Bob tells us that’s he’s going to be at Cisco Live US in San Francisco this year but he won’t be attending any sessions. He’s going with the Social Event pass this year, which is actually a great, great way to attend the conference. I know several people who are thinking about scaling back to the Social Event pass as well, and there’s nothing wrong with doing it like that. It does, however, have some shortcomings that I feel are important.
Do not tell anyone I told you, but I heard a rumor today. It looks like the attendees will be in for quite a treat for the 25th Anniversary of the Customer Appreciate Event. It seems that we’re all going…
We all know what Cisco Live is, right? Networkers? The Cisco users’ conference? If not, then educate yourself, friend. It takes place every year in different parts of the world. I try my best to go every year to the US event and am lucky to be able to go this year. It costs a bagillion dollars and a week of my time; why am I so excited about going? Easy answers in no particular order.
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.
