The previous article discusses an installation of Openswitch OPX on VirtualBox using lvm tool. We have extracted Openswitch OPX VDI disk from VirtualBoxVM and run the disk with Qemu. The image has been subsequently customized using the after install script in order to run it inside GNS3. Finally, we have tested the image within a simple GNS3 lab that proves its functionality. This article goes further and we are going to test VLANs bridging using Linux native commands.
Picture 1 - Network Topology
The lab consists of three Openswitch OPX 2.3.2 instances powered by Qemu hypervisor. The device OPX-Distrib1 is multilayer switch that is responsible for routing between VLANs 10,20,30,40 and 50. The VLANs 10-40 are end-users VLANs and the VLAN50 is used for management. The switches OPX-Access1 and OPX-Access2 are L2 switches with the port e101-001-0 configured as the trunk ports. End users are connected to the access ports e101-002-0 and e101-003-0 on both access switches.
Note: Customized Openswitch OPX 2.3.3 vdi disk can be downloaded in Download section. Login name is opxUser and the password is not set.

Last week, we wrote about implementing ESI with Cloudflare Workers. This is a guest post by Lukas Reider on how to use ESI not only for better performance, but to optimize availability while migrating backends.
In this post, you will learn about how my client Titel Media was able to use Cloudflare Workers to implement simple edge side includes.
The idea is to partially replace the parts of the online magazine highsnobiety.com with a new, and much more refined frontend implementation. In this article, you will get to know the use case, and how I found a powerful application for Cloudflare Workers.
My current project, highsnobiety.com is in the process of replacing Wordpress with a dedicated content pipeline and a custom frontend. It is a huge magazine, with tons of contents, hundreds of daily updates and an international team of more than 60 editors, researching and writing exciting stories.
The company behind it, Titel Media GmbH, a publishing house with offices in Berlin, and New York, surely has grown out of Wordpress for hosting their content.
One does not simply rewrite a sophisticated web publishing pipeline like WordPress. Nor does one, simply Continue reading
A Synergy Research Group report found that Google, Microsoft, Amazon, Apple, and Facebook accounted for 70 percent of total hyperscale capex.
The software-as-a-service (SaaS) platform recreates common Docker container failures across three categories: resource, network, and state.
Networking professionals no longer can only have a limited scope of skills. The addition of other certifications will mean more career growth and more pay.
The Internet Engineering Task Force has reached a significant milestone in the process of evolving its own administrative structure to best suit the current requirements of its work. After nearly two years of discussion about various options, the IETF community has created the IETF Administrative LLC (IETF LLC), a new legal entity. Both the Internet Society’s CEO & President Kathy Brown and the Internet Society’s Board of Trustees Chair Gonzalo Camarillo have expressed strong support for the process that has led to this point, and for the direction the IETF has decided to take. Continuing its long-standing positions, the Internet Society also made financial commitments to support the process, and to the IETF going forward.
All of us at the Internet Society who work closely with the IETF believe this new administrative structure strengthens the the foundation for an Internet built on open standards. The new structure will not change any aspect of the IETF’s technical work or the Internet standards process, and clarifies the relationship between ISOC and the IETF. Importantly, the IETF and ISOC continue to be strongly aligned on key principles. ISOC initiatives related to the IETF, such as the Technical Fellows to the IETF and the Continue reading
Last year, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. We interviewed Chris Riley to hear his perspective on the forces shaping the Internet’s future.
Chris Riley is Director, Public Policy at Mozilla, working to advance the open Internet through public policy analysis and advocacy, strategic planning, coalition building, and community engagement. Chris manages the global Mozilla public policy team and works on all things Internet policy, motivated by the belief that an open, disruptive Internet delivers tremendous socioeconomic benefits, and that if we as a global society don’t work to protect and preserve the Internet’s core features, those benefits will go away. Prior to joining Mozilla, Chris worked as a program manager at the U.S. Department of State on Internet freedom, a policy counsel with the nonprofit public interest organization Free Press, and an attorney-advisor at the Federal Communications Commission.
The Internet Society: Why is there a need for promoting a better understanding of technology amongst policy wonks, and of policy among technologists?
Chris Riley: Continue reading
Application security requires collaboration between developers and security ops. Organizations need to align expectations of the two groups and shift security to the left, into the development pipeline.
As promised, here’s the second part of my Benefits of Network Automation interview with Christoph Jaggi published in German on Inside-IT last Friday (part 1 is here).
The biggest challenge everyone faces when starting the network automation is the snowflake nature of most enterprise networks and the million one-off exceptions we had to make in the past to cope with badly-designed applications or unrealistic user requirements. Remember: you cannot automate what you cannot describe in enough details.
