I feel like a teenage girl with a fashion blog who hasn’t posted in 6 months and comes back with “I know I haven’t posted in a while…” Sigh. It’s been right at a year since I actually published a…
For the last couple years, on the Saturday before Cisco Live US kicks off, we like to go and do something in the host city. Nothing big. Nothing fancy. Just something we aren’t going to be able to do once…
Put it on your calendar. Cisco Live US is June 25 – 29, 2017, in Las Vegas. This is the largest conference I go to every year, and it’s the highlight of my professional year. I’ve been going for a…
Check out this advisory from Cisco that came out a couple days ago. I’ll summarize for you : Thanks to a faulty clock signal component, certain Cisco devices will stop functioning after about 18 months and become really expensive bricks! If you read through it, you see phrases like “we expect product failures” and “is not recoverable.”
Yes, really. QoS has actually gotten some attention this year. After how many years of living in the dark and being feared by junior and senior engineers alike, we’re seeing some really cool technologies coming out for it.
It seems that Cisco Live is about the only thing I blog about in the last…well, few years. At least I’m still writing, even if it is twice a year. 🙂
I love going to Cisco Live every year. Without question, it’s my favorite event of the year. It’s a great event with great people and great things to do. With that said, let’s look at what could have been a bit better this year.

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!
