Latest Packet Pushers Podcast Offers a New Perspective on Networking
What’s more likely to spawn change and innovation in networking? A highly-concentrated team working on a small project, or a multi-disciplinary team working on a massive project? Multiple small teams working on 100’s of projects around the globe, or one big massive team banking on a single idea? These questions and more are posed by Bruce Davie, the recently appointed CTO for Asia Pacific and Japan at VMware, and a long time contributor, collaborator, and friend of the Packet Pushers (Greg Ferro and Ethan Banks).
In a brand new Packet Pushers podcast, Bruce, Greg and Ethan take you along for an in-depth look at various networking approaches, and the changes in store for networking as a whole Hear how networking will continue to evolve: namely, how distributed application architectures and other factors are driving big-time industry shifts. Every topic is fair game, and these networking stalwarts aren’t afraid of challenging status quo thought processes to uncover new theories. So, prepare yourself for a lively discussion and debate that transcends the present, and heads straight into the future of networking.
For those who haven’t already hurried to plug in, here’s a preview of a couple topic areas Continue reading
The Linux Migration: Other Users’ Stories, Part 1
Shortly after I announced my intention to migrate to Linux as my primary desktop OS, a number of other folks contacted me and said they had made the same choice or they had been encouraged by my decision to also try it themselves. It seems that there is a fair amount of pent-up interest—at least in the IT community—to embrace Linux as a primary desktop OS. Given the level of interest, I thought it might be helpful for readers to hear from others who are also switching to Linux as their primary desktop OS, and so this post kicks off a series of posts where I’ll share other users’ stories about their Linux migration.
In this first post of the series, you’ll get a chance to hear from Roddy Strachan. I’ve structured the information in a “question-and-answer” format to make it a bit easier to follow.
Q: Why did you switch to Linux?
I was a heavy Windows user due to corporate requirements. It was just easy to run Windows. I never ran the standard corporate build, but instead ran my own managed version of Windows 10; this worked well. I switched because I wanted to experiment with Linux Continue reading

Five Functional Facts About OSPF
It’s funny, in my exerperience, OSPF is the most widely used interior gateway protocol because it “just works” and it’s an IETF standard which means it interops between different vendors and platforms. However, if you really start to look at how OSPF works, you realize it’s actually a highly complex protocol. So on the one hand you get a protocol that likely works across your whole environment, regardless of vendor/platform, but on the other you’re implementing a lot of complexity in your control plane which may not be intuitive to troubleshoot.
This post isn’t a judgement about OSPF or link-state protocols in general. Instead it will detail five functional aspects of OSPF in order to reveal–at least in part–how this protocol works, and indirectly, some of the complexity lying under the hood.
1. OSPF Has Its Own Best Path Decision Process
Ever looked closely at OSPF routes in the show ip route output? You’ll notice flags such as O or O IA beside the route.

O IA 11.11.11.0 [110/20] via 123.1.0.18, 00:00:07, Ethernet0/0
