This Week: Data Center Deployment with EVPN/VXLAN
Brand new book – This Week: Data Center Deployment with EVPN/VXLAN.
Author did a great job explaining and showing various examples of real world implementations of EVPN-VXLAN and DCI.
Definitely must read for anybody aiming for JNCIE-DC lab. I wish I’ve read this before my lab attempt – this book really helps to update and systematize all EVPN-VXLAN related knowledge.
But that’s for sure not the first book to read if you doesn’t know anything about EVPN-VXLAN. I recommend firstly read all materials from this post, and only after that this book will be really useful to you.
Network Engineer Jobs
So you want to work for Google as Network Engineer? Check out one of the job ads here. I pasted the screenshot below just in case the ad is removed once the position is no longer available.
"You'll build software for distributed services, abstractions and the components of the system that operates and powers Google." OK, even this is not common in Network Engineer job description, it makes sense since Google is running one of the world's largest networks to connect its data centers that are scattered all around world. As minimum requirement, you must have experience in software development in one or more modern programming languages e.g. C++, Java, Python, Go, etc. And learn how to code using "Teach yourself Python in 24 hours" won't be enough since it is expected for you to have experience in data structures, complexity analysis and software design.
Is Google really looking for Network Engineer (NE), and not Software Engineer (SWE)? Yup, you still need to have expertise in networking protocols and technologies, including end-to-end packet flow, forwarding and routing. Google knows that a world class distributed computing infrastructure must run on world class networking infrastructure that is operated reliably and Continue reading
The Concept of Native VLAN
Today I am going to talk about one of the most interesting topic and its none other than Native VLAN. I knew most of you guys know the concept and the requirement of the Native VLAN and most of you already using and configuring the same in your network environment. But there are so many people just starting studying the basics of the networking and this is one of the most important topic to understand the basics of switching.
In my example I am taking the Cisco devices where I will show the Native VLAN working and the configurations of the Native VLAN on the devices.
So my first question is What is Native VLAN ?
What is the Use of the Native VLAN ?
When and where to use the Native VLAN concept ?
Standards of the Native VLANs ?
I knew there are lot of questions in your mind, So lets start with the beginning on the Native VLAN part. The IEEE 802.1Q trunking protocol describes some thing called the “native VLAN”. All site visitors sent and acquired on an interface that is configured for 802.1Q gained have a tag on its Ethernet body. whilst you look Continue reading
Discovery Protocols- CDP and LLDP
Today I am going to talk about the CDP and LLDP protocols. As you guys already knew of CDP, I think most of you are using this command in your daily use to find the connected devices in Cisco devices environment while LLDP is same as CDP but it is a standard protocol for all other Vendors.
So If I am talking about the CDP, CDP Stands for Cisco Discovery Protocol and LLDP stands for Link Layer Discovery Protocol. The role and the working is same for both of these protocols.
CDP is a Cisco proprietary protocol and can be used only on Cisco devices While LLDP is the standard protocol and can be used for interworking between different network vendors. We need to know only CDP with regards to discovery protocols. But it is always good to go beyond and above what is required in the exam topics. You might find yourself in the situation where you have to monitor and configure a multi-vendor network. LLDP knowledge will come in handy in that situation.

MPLS Design Scenario : Penultimate Hop Popping (PHP)
Today I am going to talk about one of the best practices we are doing while we configuring MPLS in our network. This post is basically for the Service Providers who provide MPLS services to their clients. Let's talk about the concept PHP in details. PHP Stands for penultimate hop popping.
Before you go with this article, Lets review all the articles which can be relevant with the service Provider Domain. Below are the links of these articles.
Now Let's talk about the PHP, PHP is penultimate hop popping which means remove the label one hop before its destination.It refers to the process whereby the outermost label of an MPLS tagged packet is removed by a Label Switch Router (LSR) before the packet is passed to an adjacent Label Edge Router.
Below is the diagram showing the PHP operation in MPLS environment

The process is important in a Layer 3 MPLS VPN environment as it reduces the load on Continue reading

NFD16 First Impressions
Getting bored sitting at San Jose airport waiting for Vagrant to update guest additions in my Ubuntu VM (first item on my to-do list: prepare final version of material for next week’s Docker workshop), so here are my very first impressions of Networking Field Day 16 presentations we’ve seen in the last three days.
As always, there were great presentations, good presentations, … and a few that are best forgotten. I won’t mention those.

Last week we announced the names of twenty-five individuals who were selected as the awardees of our 25 under 25 program, an initiative which recognizes young people from around the globe who are using the Internet to make a positive difference.
The program forms part of the Internet Society’s 25th Anniversary celebrations this month, including a special recognition ceremony planned in Los Angeles, California on Monday 18 September for the 25 under 25. We invited all twenty-five awardees to Los Angeles to take part and receive their awards in person but we have learnt that unfortunately, not everyone will be able to travel. Three of the awardees have not been granted visas to enter the United States.
On hearing this news one awardee, Mariano Gomez, penned us an open letter. In it, he explains his frustration at a process which required him to travel over several days to a ten minute interview which resulted in rejection. He described with utter clarity the irony of being denied entry due to the very conditions he hopes to address with the innovations he is pursuing on the Internet.
We understand and applaud Mariano’s statement. Not only are we disappointed that he and two Continue reading

New BlueBorne Vulnerability to Bluetooth Devices – What happened and what to do about it
Billions of Bluetooth-enabled devices may be exposed to a new remote attack called “BlueBorne”, even without user interaction or pairing. Affected systems include Windows, iOS (older than iOS 10), the Linux kernel, and Android. What should you do about it?
Bluetooth is ubiquitous, commonly connecting accessories like headsets and keyboards, but is also used throughout the brave new Internet of Things (IoT) world. An attacker exploiting these BlueBorne vulnerabilities can mount a man-in-the-middle attack, or even take control of a device without the user even noticing it.
The vulnerabilities were discovered by a security company called Armis earlier this year. Researchers reached out to the companies responsible for vulnerable implementations that lead to the coordinated disclosure (and patches) on September 12. (You can read more about our views on responsible disclosure and collaborative security in Olaf Kolkman’s blog post here.)
This case once again highlights how crucial it is that software update mechanisms are available to fix vulnerabilities, update configuration settings, and add new functionality to devices. There are challenges, both technological and economic, in having update capabilities ubiquitously deployed, as discussed in the recently published Report from the Internet of Things Software Update (IoTSU) Workshop 2016.
Vulnerabilities Continue reading
