Another Cyber-attack : Petya Cyberattack after Wannacry Shutdowns Europe
Another Cyber-attack shocked Europe as many of the Firms like Airport industries, Banks, Government departments effected by this Petya Cyberattack. It was said that it is the beginning of the attacks and will have many more attacks in near future. Cyber security is one of the most demanding feature now a days who can save you from these cyber attacks.
Experts says, Petya Ransomware attack is just a test and will come up with more worse in the future. So you need to take care about the attacks by applying best security features like Cisco OpenDNS as a first line of security of the big and the other enterprise networks.
Many of the vendors come up with their inputs on the cyberattack where most of the industries across Ukraine, Russia and some part of Europe effected. Most of the firms from Danish and Spanish are effected as well. It may grow towards the Asia and the American region but still no footprints of these attacks.
It is said that ( the effected industries review)- The virus is believed to be ransomware - a piece of malicious software that shuts down a computer system and Continue reading

Control Plane for our L3VPN based virtual network
In the last two blogs, I have gone through the process of developing a L3VPN base virtual network. One thing that we ignored is the amount of configuration that we need to change to add or remove nodes or provision new edge routers. While, some of these steps are part of the infrastructure provisioning, like … Continue reading Control Plane for our L3VPN based virtual network
Designing a L2 virtual network with L3VPNs
In the previous blog, we saw how we can connect two devices in the same subnet over a L3 device. With some configuration to enable ARP Proxying and host routes on the L3 device we were able to simulate a L2 network over a L3 device. The important thing to note from the previous blog … Continue reading Designing a L2 virtual network with L3VPNs
Using a Router for Switching
We all know that Routers are Layer3 devices and switches are Layer2. So how can a Layer 3 device be used to connect two or more devices at Layer2 ? In this blog, I will explore the mechanisms that make it possible to use a routing device as a switch. The test setup We start … Continue reading Using a Router for Switching
How Do I Start Automating Network Device Configurations in an Existing Network?
I get a “how do I get started with network automation” question every other week, and when I wrote a lengthy reply to one about configuration templating of existing snowflake network on networktocode Slack channel I decided it’s time to turn my replies into a blog post.
Read more ...Why EVPN on Cumulus Linux makes our CTO yell “Booyah!”
I started coveting IP encapsulated network virtualization back in 2005 when I was working to build a huge IP fabric. However, we needed to have layer 2 (L2) adjacencies to some servers for classic DSR load balancing. The ideal solution was to have something that looked like a bridge as far as the load balancers and servers were concerned, yet would tunnel unmodified L2 frames through the IP fabric. Alas, we were way ahead of our time.
Thank the IT gods that things have changed quite a bit in the last 12 years. Today, we as an IT community have VXLAN, which is embodied in most modern networking silicon and (a bit more importantly) realized as part of the Linux networking model so that it’s really straightforward to deploy and scale. IT geeks have a bunch of ways to build L2 domains that are extended across IP fabrics using VXLAN. There are dedicated SDN controllers, such as Contrail, Nuage, Midonet and VMware NSX; there are orchestration-hosted controllers in OpenStack Neutron and Docker Swarm; and there are simple tools like the lightweight network virtualization that we built at Cumulus Networks.
This all leads me to EVPN. We recently made EVPN available Continue reading
