Over three years ago I saw an opportunity to take an assignment to my company HQ in Seattle. After debating this for some time with my wife we took the plunge and moved to the US. The question is, “was it worth it?”. For me the answer is an overwhelming ‘yes’. I’m moving back to […]

I finished reading The Phoenix Project at the beginning of May and it has had a profound affect on my outlook towards work. Not only was this a great read, but while I was reading I kept getting ideas on how I could implement the three ways at work. This diary documents the transition to an Agile Writing workflow.
I recently changed from MultiMarkdown to Pandoc. But I still wanted to use Marked app to preview my work…
For the last 6 months I've been using Markdown where I can. Since embarking on the path towards a more Agile approach to writing, it has been necessary to use Markdown more and more. This has led me towards using Pandoc Markdown rather than MultMarkdown as my dialect of choice and I hope to explain why.
People new to MPLS VPN are often unclear on what functions route distinguishers and route targets serve, and the difference between the two. Let's see if we can clear up some of that confusion. If you could use a refresher on VRF fundamentals, I encourage you to first check out my earlier articles on the topic, Intro to VRF lite and Inter-VRF Routing with VRF Lite.
As you know, VRFs allow IP address space to be reused among isolated routing domains. For example, assume you have to connect to three customer sites, all of which are using 192.168.0.0/24 as their local network. We can assign each customer its own VRF so that the overlapping networks are kept isolated from one another in their respective routing domains.
This works well, but we need a way to keep track of which 192.168.0.0/24 route belongs to which customer. This is where route distinguishers come in. As its name implies, a route distinguisher (RD) distinguishes one set of routes (one VRF) from another. It is a unique number prepended to each route within a VRF to identify it as belonging to that particular VRF or customer. Continue reading
Packet Design will be exhibiting at MPLS/SDN 2013 from November 17-20 in Washington, D.C. We'll be showcasing Route-Flow Fusion℠ from our booth where you can pick up one of our new 'Now I know everything' T-shirts.

I've had enough real life experience with replacing drives in the ZFS pool in my home NAS that I feel comfortable sharing this information with the community.
It’s only been a couple of short weeks since this site officially launched. I have to say that I’m thrilled with the initial ‘buzz’ around the site. Many friends from various other technical blogs and social networking circles have shared The Tech Interview with their friends. In addition to thanking everyone for sharing this site, […]
The post How Can The Tech Interview Help Fill the Technical Career Gap? appeared first on Packet Pushers Podcast and was written by Paul Stewart.
Was knocking my head against a brick wall trying to configure an ACE for management for a couple of days. Turns out, it does not permit ICMP to it by default.
This is a good place to start:
So you need to configure a class map classifying ICMP traffic from specific sources as being interesting, a policy map referencing the class map, an action for matching traffic and then apply that using the “service-policy” command to the interface you want to permit traffic to.
Everything is well as long as it’s only management traffic you want to permit to this address.
Barbie films (yes, I really am talking about Barbie in a network blog post) are a big hit with my kids, and surprisingly with me too. I’ll possibly regret telling the world that, but anyway, there’s an exchange in one film* that always make me laugh. It goes like this. Human (Australian accent): “You’re bonkers!” […]

How does the internet work - We know what is networking
This story will be a turning point for my blog future starting with a change in writing methods and changing those methods to a more causal fashion. INTRO For now all my text here where somehow depersonalized and tech oriented in a way that it was all written like in some book. User manual to me concise. Maybe this […]
So, there I was, innocently browsing the OpenDaylight wiki after listening to Show 148 – Talking With OpenDaylight Leadership when I came across the OpenDaylight Command Line Interface page. I’ve not gone through the entire 118 pages (if I were to print it) worth of content, but I’ve scanned through a fair chunk and read the CLI Concepts section in […]

Cisco Live is a wonderful opportunity to meet people and have in-depth technical discussions. For me, I find this event to be a great venue to finally see those that I have had numerous online interactions with. It serves as a way to elevate these relationships to a new level. In John’s article entitled “Build […]

I’ve just passed a year of my job working at a smallish non-profit, and one part that I really am enjoying is passing on knowledge to the front-line staff. This week, there was an interesting case, and I had to explain to my colleagues what was happening and why. So, I did a little demo, and […]
