VxLAN on the CSR1Kv

By now, VxLAN is becoming the standard way of tunneling in the Datacenter.
Using VxLAN, i will show how to use the CSR1Kv to extend your Datacenter L2 reach between sites as well.

First off, what is VxLAN?
It stands for Virtual Extensible LAN. Basically you have a way of decoupling your vlan’s into a new scheme.

You basically map your VLAN into a VNI (Virtual Network Identifier), which in essence makes your VLAN numbering scheme locally significant.

Also, since the numbering for VNI’s is a 24 bit identifier, you have alot more flexibility than just the regular 4096 definable VLAN’s. (12 Bits .1q tags)

Each endpoint that does the encapsulation/decapsulation is called a VTEP (VxLAN Tunnel EndPoint). In our example this would be CSR3 and CSR5.

After the VxLAN header, the packet is further encapsulated into a UDP packet and forwarded across the network. This is a great solution as it doesnt impose any technical restrictions on the core of the network. Only the VTEPs needs to understand VxLAN (and probably have hardware acceleration for it as well).

Since we wont be using BGP EVPN, we will rely solely on multicasting in the network to establish who is the Continue reading

IDG Contributor Network: The future of disaster recovery lies in a future without the public internet

What is it that’s driving enterprises to the cloud?That’s a long list: Web-based storage, stability, easier remote access and reductions in maintenance and associated costs are a few of the most frequently cited reasons. But, the number one application on organizations’ minds when they’re mapping out cloud migration strategies is disaster recovery (DR). Consequently, disaster recovery has become a primary source of value for enterprises who are not only pursuing cloud adoption, but who are also building out hybrid- or multi-cloud strategies.To read this article in full or to leave a comment, please click here

Docker brings containers to mainframes

Docker announced the first major update to its flagship Docker Enterprise Edition 17.06, with a clear eye to on-premises data centers and DevOps. Docker rolled out the rebranded Docker EE in March, based on what was previously known as the Docker Commercially Supported and Docker Datacenter products. With that launch, Docker added the ability to port legacy apps to containers without having to modify the code.The major new feature of this update — which seems to borrow from Microsoft’s year/month naming convention for Windows 10 updates — is support for IBM z Systems mainframes running Linux. Now containerized apps can be run on a mainframe, with all of the scale and uptime reliability it brings, and they run with no modifications necessary.To read this article in full or to leave a comment, please click here

6 Questions to Ask Your SD-WAN Vendor

Worth Reading: Transitioning to a single root

APNIC is in the process of transitioning from the current Resource Public Key Infrastructure (RPKI) trust anchor arrangement to a new configuration which has been agreed among the RIRs, and announced by the NRO. In this new configuration, each RIR will publish an “all resources” global trust anchor, under which its own regional resources (IP addresses and ASNs) will be certified. —Tom Harrison @ APNIC

IoT is about to tell you when your food is spoiled

“It’s not getting any younger.”In my house, that’s code for either eating or trashing something in the refrigerator that’s flirting with its “best-by” date — or just no longer looks as appetizing as it once did.Sensors are the core of the Internet of Things But what if Internet of Things (IoT) sensor technology could tell you whether that lasagna was still safe for dinner or whether it’s time to toss the hair-coloring product slowly drying out in the back of your medicine cabinet? That promise is what’s on the menu at the 254th National Meeting & Exposition of the American Chemical Society (ACS) in Washington, D.C., this week. So, what does the world’s largest scientific society, with more than 157,000 members, have to do with IoT? To read this article in full or to leave a comment, please click here

Disaster Recovery with VMware NSX-V and Zerto

Note, this is a reposting of the blog that I initially posted here on humairahmed.com. In a prior blog, VMware NSX and SRM: Disaster Recovery Overview and Demo, I described and demoed how VMware NSX and SRM with vSphere Replication combined provide for an enhanced disaster recovery (DR) solution. SRM also provides additional integration with NSX when Storage Policy Protection Groups (SPPGs) are used by providing the ability to automate network mappings. One of the great things about the NSX-V platform, is it can be used with any DR orchestration tool that supports the VMware vSphere ESXi hypervisor. Some of the tools customers are using with NSX include VMware SRM, Dell EMC RP4VM, Zerto, and Veeam. As SRM was discussed and demonstrated in a prior blog, Zerto and NSX together is explained in more detail below.  Continue reading

Wait, what happened to my choices?

This weekend, I experienced one of those moments that make me question the value of information technology. My trusty windows phone, for whatever reason, failed. Given I was traveling in less than 24 hours, I needed to find a replacement. So I traipsed to the local phone store, and was told “I’m sorry, we don’t sell windows phones. They aren’t popular enough.” So there I stood, like the shopper in the proverbial aisle of cereal, trying to choose which new phone to get.

After staring at all the different phones for a while, it dawned on me that the apparent variety is fake. I really only had two choices.

The first is the iPhone. The iPhone is a throwback to the late 1990’s, at least one generation behind current hardware, and with a user interface that falls into the “cute retro gamified Windows 3.11/Xerox Star” sort of thing. Getting anything done requires jumping through multiple hoops. There is no way to pin anything you use on a regular basis to the screen, no information available without entering an app, the icons are tiny candies, etc. Sorry Apple fanfolk, but Apple hasn’t innovated in at least 10 years in Continue reading

Worth Reading: What if everything you know about passwords is wrong?

Every time there’s a notable cybersecurity breach, someone (even me) writes a comprehensive primer on the proper way to create “secure” passwords. Lather, rinse, repeat. Until a few years ago, everyone (including me) based their password advice on a 2003 paper from the National Institute of Standards and Technology (NIST), with the catchy title “NIST Special Publication 800-63.” The paper recommended that passwords be cryptic, contain special characters, and be as close to nonsense as possible. —Shelly Palmer
