EVPN-VXLAN INTER-TENANT ROUTING ON JUNIPER QFX / MX

evpn-vxlan-title

I’ve recently started working on a project focused on EVPN-VXLAN based on Juniper technology. I figured I’d take the opportunity to share some experiences specifically around inter-VXLAN routing. Inter-VXLAN routing can be useful when passing traffic between different tenants. For example, you may have a shared-services tenant that needs to be accessed by a number of different customer tenants whilst not allowing reachability between customer tenants. By enabling inter-VXLAN routing on the MX we can use various route-leaking techniques and policy to provide a technical point of control.

Notes from IETF 99 – The IEPG Meeting

Many years ago the IEPG had a role in allowing network operators to talk to other operators about what they were seeing and what they were thinking about. Those days are long since over, and today the IEPG meetings present an opportunity for an eclectic set of diehards to listen to an equally eclectic collection of presentations that wander over much of the topics of today's Internet, without any particular common theme or filter.

JUNIPER NORTHSTAR UPGRADE 2.1 TO 3.0

In this post, I’m quickly going to describe how to upgrade NorthStar 2.1 to 3.0. For a detailed installation and user guide refer to the 3.0 release notes here.

Firstly, let’s start off by verifying the current host OS and NorthStar versions. Note. NorthStar 3.0 requires a minimum of Centos 6.7 or above.

[root@northstar ~]# cat /etc/redhat-release
CentOS release 6.9 (Final)

To check the current version of NorthStar, navigate to the about section via the drop down menu located at the top right of the GUI

Download NorthStar, Extract & Copy:

Download the NorthStar 3.0 application from Juniper.net NorthStar download page. Once downloaded, extract the RPM and copy to your host machine. Below I have copied the NorthStar-Bundle-3.0.0-20170630_141113_70366_586.x86_64.rpm to the /root/rpms/ directory.

Worth Reading: AMD and the Infinity Fabric

Starting with AMD’s Ryzen desktop processor and Epyc server architecture, AMD will implement their scalable Infinity Fabric across all its SoC and MCM products. Think of Infinity Fabric as a superset of HyperTransport, AMD’s previous socket-to-socket interconnect architecture, now managed by the HyperTransport Consortium. Infinity Fabric is a coherent high-performance fabric that uses sensors embedded in each die to scale control and data flow from die to socket to board-level. —The Next Platform

Beware of companies claiming products have AI capabilities

Software companies are exploiting the current artificial intelligence (AI) craze by exaggerating the scope and capabilities of AI in their products, according to a report from Gartner. Gartner tracks product marketing hype with a tool it calls the Hype Cycle, measuring the growth and decline of products as they mature. It calls the process of overhyping AI "AI washing," similar to the way the term “greenwashing” was used to describe exaggerated claims of environmental-friendliness in various products or practices. Gartner said more than 1,000 vendors say their products employ AI, but many are "applying the AI label a little too indiscriminately." And it has happened fast.To read this article in full or to leave a comment, please click here

Context From The People

Are you ready for the flood of context-based networking solutions? If not, it’s time to invest in sandbags. After the launch of Cisco’s Intuitive Network solution set at Cisco Live, the rest of the context solutions are coming out to play. Granted, some of them are like Apstra and have been doing this for a while. Others are going to be jumping on the bandwagon of providing a solution that helps with context. But why are we here and why now?

Creating Context

The truth is that we’ve had context in the network for decades now. It’s not a part number that we can order from a vendor. It’s not a command that we type into the CLI to activate. In fact, it’s nothing that you can see at all right now, unless there’s a mirror handy.

The context in networks has been provided by people for as far back as anyone can remember. You do it every day without consciously realizing it. You interpret error messages and disregard those that aren’t important. People know how to program VLANs correctly to segment traffic in certain ways. Security context, application context, and more are delivered by breathing, thinking humans.

We have Continue reading

Docker Community Spotlight: Adina-Valentina Radulescu

Adina-Valentina Radulescu, a DevOps/Integration Engineer for Pentalog Romania, has been organizing meetups for not one but two meetup groups.

In February of last year, Adina founded Docker Brasov and Docker Timisoara, and has since done an amazing job creating and fostering a sense of belonging in her community. This month, we’re happy to shine the community spotlight on Adina to learn more about her Docker story.

Tell us about your first experience with Docker.

The first time I heard about Docker was back in 2014. I played around with Docker and I was impressed with the simplicity of integration so I wanted to learn more. I was able to attend DockerCon EU in 2015 in Barcelona where I completed some labs and attended the talks to learn as much as I could about Docker. It was a powerful feeling.

Why did you start Docker Brasov and Docker Timisoara?

I wanted to have a Docker sharing exchange experience when I get back in Romania. I relocated from Timisoara to a beautiful mountain city, Brasov. In Timisoara, I knew people and companies. In Brasov, I knew almost no one. This is why I decided to start the two groups so I Continue reading

Worth Reading: Is Decentralized Storage Sustainable?

There are many reasons to dislike centralized storage services. They include business risk, as we see in le petit musée des projets Google abandonnés, monoculture vulnerability and rent extraction. There is thus naturally a lot of enthusiasm for decentralized storage systems, such as MaidSafe, DAT and IPFS. —DHSR
