In the context of the Internet and BGP routing, DFZ – commonly known as Default Free Zone – refers to the collections of all the public IPv4 BGP prefixes without default route on the global Internet. Most of the time, you hear full-route or full-Internet-route terms which are the same with Default Free Zone term. Having all BGP routes, […]

Follow these best practices to avoid security pitfalls with your Internet of Things deployment.
A look at the evolution of a technology that's poised to make big waves in storage.
One of my ExpertExpress engagements focused on networking in a future private cloud that might be built using OpenStack. The customer planned to deploy multiple data centers, and I recommended that they do everything they can to make sure they don’t make them a single failure domain.
Next step: translate that requirement into OpenStack terms.

Before moving on the next post to continue our saga of OpenSwitch Simulations with GNS3, I wanted to take a quick deviation to document a subject that gets a lot of attention these days: P4.
In case you have been missing all the action around P4, the 30,000 feet view is that it’s a language to describe forwarding pipelines (and no, it’s not the same as OpenFlow, that is useful for programming entries in almost-always-pre-defined pipelines). One of the (many) nice things about this is that you can potentially ‘compile’ your pipeline definition into an executable program that provides a functional simulation of a P4-based ASIC. Did I mention the tools for doing all of this are available as open source?
Cloudify also spawns a new open source group: Aria.
Congratulations to Neil Moore on passing the CCDE Practical Exam this week, and becoming a NONTUPLE (9x) CCIE & CCDE!
Neil was a student in both my CCIE Data Center Bootcamp and CCDE Bootcamp within the past few years, and is truly an inspiration to us all. Neil’s brother Kelly is also a CCIE in Data Center. Neil likes to introduce himself and his brother to people at Cisco Live that they have 9 CCIEs between the two of them! This year Neil gets to bump that up to 10 CCIEs and CCDE between the two of them!
Neil for sure will win the longest badge this year at Cisco Live 2016 Las Vegas!
Neil currently works for VMWare as an NSX Systems Engineer, is a VMware Certified Implementation Expert — Network Virtualization (VCIX-NV), and has plans to pursue the VMware Certified Design Expert (VCDX).
Congrats Neil!
