Generating OSPF, BGP and MPLS/VPN Configurations from Network Data Model

Over a month ago I decided to create a lab network to figure out how to solve an interesting Inter-AS MPLS/VPN routing challenge. Instead of configuring half a dozen routers I decided to develop a fully-automated deployment because it will make my life easier.

I finally got to a point where OSPF, LDP, BGP (IPv4 and VPNv4) and MPLS/VPN configurations are created, deployed and verified automatically.

Looking Back: 2016 Project Report Card

As I’ve done for the last few years, in early 2016 I published a list of my planned personal projects for the year. In this post, I’d like to look back on that list of projects and grade myself on my progress (or lack of progress, if that is the case). Even though 2016 isn’t over yet, it’s close enough to the end of the year that things won’t change that much before 2017 is upon us.

For reference, here’s the list of planned 2016 projects:

  1. Complete a new book (again)
  2. Make more open source contributions
  3. Expand my knowledge and use of Python
  4. Expand my knowledge, use, and focus on public cloud services
  5. Complete a “wildcard project”

Let’s look at each of these planned projects and see how I fared.

  1. Complete a new book (again): Well—in the spirit of total honesty and transparency—this was a major failure. Not only did I fail to complete the network automation book I’ve been working on with Matt Oswalt and Jason Edelman, but the other book project I had planned also did not go anywhere. Granted, the circumstances preventing the second book project were outside my control, but the fact remains I still did Continue reading

“From Putin with Love” – a novel by the New York Times

In recent weeks, the New York Times has written many stories on Russia's hacking of the Trump election. This front page piece [*] alone takes up 9,000 words. Combined, the NYTimes coverage on this topic exceeds the length of a novel. Yet, for all this text, the number of verifiable facts also equals that of a novel, namely zero. There's no evidence this was anything other than an undirected, Anonymous-style op based on a phishing campaign.


The question that drives us

It's not that Russia isn't involved, it's that the exact nature of their involvement is complicated. Just because the hackers live in Russia doesn't automatically mean their attacks are directed by the government.

It's like the recent Islamic terrorist attacks in Europe and America. Despite ISIS claiming credit, and the perpetrators crediting ISIS, we are loathe to actually blame the attacks directly on ISIS. Overwhelmingly, it's individuals who finance and plan their attacks, with no ISIS organizational involvement other than inspiration.

The same goes for Russian hacks. The Russian hacker community is complicated. There are lots of actors with various affiliations with the government. They are almost always nationalistic, almost always pro-Putin. There are many individuals and Continue reading

Worth Reading: Driverless infrastructure

It turns out machines can deploy software much better than humans can. Why? Because software deployment is a set of mechanical procedures that can be driven by a declarative language. It is a process primed for a systematic approach done right, and reproducibly. This is especially important as patches and security fixes are applied to software — a ritual that should be repeatable and seamless. —The New Stack

IDG Contributor Network: Reshaping the project manager role for the digital age

Recent IT labor market analysis from CEB reveals that "IT project manager" is the most difficult-to-fill IT role globally. This comes as no surprise to IT and project management leaders who have consistently struggled to find the right talent to oversee their most critical projects and programs. As organizations strive to digitize, the challenge of finding skilled IT project managers will only increase. The type of work that supports the typical organization’s digitization ambitions—rapid, often iterative, and typically involving new technologies or processes—is the type of work that the average, process-focused project manager isn’t well equipped to handle.To read this article in full or to leave a comment, please click here
