BGP Route Reflector routing loop problem !

BGP Route reflector routing loop arise in IP networks. In this post, I will illustrate the topology which will loop the IP packets between the routers and I will describe multiple possible solution and share a best practice to design BGP Route Reflector in an IP network.       BGP Route Reflector Routing loop […]

BGP Peer Groups

Today I am going to explain the concept of the BGP peer groups. So if you able to understand the concept by name as they have a group by which they share same kind of policies and the configurations. Now the question is why we are doing this. 

Sometimes we have a network where we really want to deploy the same kind of the configuration with the same policies and we can achieve in two different ways. One is to configure all the router one by one manually and it is a time consuming task. The other way to define the same set of the configurations and the policies is to set up with the peer groups in the BGP. So if there are 4 routers and we want to have these routers with same kind of configurations and the policies we can set all of them in a peer group.

So with the above explained definition hope you guys understand the concept of the peer group. Now we are going to talk about the configuration with the help of the topology. The Topology and the IP used in this article is for demo purposes and has no relevance Continue reading

Why We Terminated Daily Stormer

Earlier today, Cloudflare terminated the account of the Daily Stormer. We've stopped proxying their traffic and stopped answering DNS requests for their sites. We've taken measures to ensure that they cannot sign up for Cloudflare's services ever again.

Our terms of service reserve the right for us to terminate users of our network at our sole discretion. The tipping point for us making this decision was that the team behind Daily Stormer made the claim that we were secretly supporters of their ideology.

Our team has been thorough and have had thoughtful discussions for years about what the right policy was on censoring. Like a lot of people, we’ve felt angry at these hateful people for a long time but we have followed the law and remained content neutral as a network. We could not remain neutral after these claims of secret support by Cloudflare.

Now, having made that decision, let me explain why it's so dangerous.

Where Do You Regulate Content on the Internet?

There are a number of different organizations that work in concert to bring you the Internet. They include:

  • Content creators, who author the actual content online.
  • Platforms (e.g., Facebook, Wordpress, etc.), where Continue reading

NSX Sessions for the Geeks at VMworld 2017

This year at VMworld 2017 we have a great agenda full of highly technical sessions around NSX.  Over the past few years NSX has expanded to meet a variety of use cases as our Content Catalog clearly shows. Based on the project your working on today, check out our recommendations for the best technical sessions for these specific NSX use cases:

  1. General overview sessions
  2. Security
  3. NSX & Cloud Native Apps
  4. Application Continuity
  5. Automation
  6. Design & Architecture

General NSX Sessions:

TS7003KU: Transforming Networking and Security for the Digital Era

Speakers: Milin Desai, Tom Corn and 3 customers

At a time when changes to technology are coming at us at a fast pace, how do customers meet and exceed business expectations? This session will focus on how customers are on their SDDC journey in context of network and security. Through the lens of the customer we will share what drives adoption, technology updates, team dynamics and becoming part of the overall business success.

NET3282BU: The NSX Practical Path

Speakers: Nikhil Kelshikar, Ron Fuller

We will share how customers have found value with NSX by getting started with one of the use cases around Security, Automation or App continuity. We will show Continue reading

Worth Reading: The shape of HPC and AI iron to come

In the IT business, just like any other business, you have to try to sell what is on the truck, not what is planned to be coming out of the factories in the coming months and years. AMD has put a very good X86 server processor into the market for the first time in nine years, and it also has a matching GPU that gives its OEM and ODM partners a credible alternative for HPC and AI workload to the combination of Intel Xeons and Nvidia Teslas that dominate hybrid computing these days. —Timothy Prickett Morgan @ The Next Platform

PCAP PCAP PCAP – Changes to RJ Store

I made a couple changes to the RouterJockey store this week and I wanted to make sure I got the word out. Previously the store worked in sprints that I tried to open up 2-3x a year. Instead of trying to manage these sprints, and keep the products updated, I’ve now made the store available year round. It still operates in sprints, but instead of being 2-3 weeks long, they’re only 3-4 days each.

On top of being more available, the store now has a few new products, nothing too exciting, but we do have a RJ phone case, a PCAP mug, and a couple stickers for sale. Teespring has recently added these products and as I get requests for other products I will be sure to add them. As usual, if you have any questions, hit me up on twitter or use the contact form.

Expand Wi-Fi quickly, easily with Aerohive’s wall plate

In many industries, it’s critical to get Wi-Fi everywhere, but it can often be difficult accomplish this. For example, extending a hotel comprised of smaller cottage-type rooms or one with lots of suites has many hard to reach places with traditional access point (AP) placement. Dorm rooms or hospitals typically want Wi-Fi everywhere, but it’s often difficult to provision it because of interference from thick walls or other infrastructure. One possible solution is to put an AP in every room, but that can get prohibitively expensive given the cost of APs and the expense of running new cables to every location.Another option has been the growing number of “wall plate” APs where the existing wall plate is removed and an AP in the form factor of a wall plate is connected into the existing Ethernet cable, bringing Wi-Fi to that location.To read this article in full or to leave a comment, please click here

Where Serverless And Event Driven Computing Collide

Every new paradigm of computing has its own framework, and it is the adoption of that framework that usually makes it consumable for the regular enterprises that don’t have fleets of PhDs on hand to create their own frameworks before a technology is mature.

Serverless computing – something that strikes fear in the hearts of many whose living is dependent on the vast inefficiencies that still lurk in the datacenter – and event-driven computing are two different and often associated technologies where the frameworks are still evolving.

The serverless movement, which we have discussed before in analyzing the Lambda efforts …

An Exascale Timeline for Storage and I/O Systems

The more things change, the more they stay the same.

While exascale supercomputers mark a next step in performance capability, at the broader architectural level, the innovations that go into such machines will be the result of incremental improvements to the same components that have existed on HPC systems for several years.

In large-scale supercomputing, many performance trends have jacked up capability and capacity—but the bottlenecks have not changed since the dawn of computing as we know it. Memory latency and memory bandwidth remain the gating factors to how fast, efficiently, and reliably big sites can run—and there is still …
