In this post, I will mention about a real project which was completed successfully in network design for one of the best online shopping customer in Turkey. In my previous post, I explained Active-Active Multihoming EVPN-VXLAN design. I implemented this technology to
Multichassis LAG concept is common in datacenter environment. Arista called it MLAG. However, some customer can demand multi vendor environment. As you know, in MLAG/MCLAG/VPC environment, there is software restriction being familiar or same vendor should be, etc. But there is another concept that is Active-Active Multhioming which use Ethernet
In previous post, I have mentioned about some simple scripting of Python for Arista. But today we will take a bigger step to automation of network. We will mention about Ansible and its components such that playbook, inventory and using to Arista topologies. We will not
In this post, I will give small sample about python scripting code for Arista devices. As you know, network engineering has been evolving to learn automation with network equipments. Many companies has started to drop CLI in devices and using automation tools to operate their devices.
EVPN technology is improved in order to eliminate some limitations of VPLS. RFC7432 gives large details of Ethernet Virtual Private Network. EVPN simply provides to carry mac address table in network environment from PE router to another PE routers, which are called here VTEPs.To do this, there are some requirements
VXLAN is virtual extensible local area network. As you guess from definition, you can extend a VLAN via VXLAN technology. We will touch on extension mechanism in this post and why VXLAN is needed in nowadays network topologies. VXLAN is introduced in RFC7348. Nowadays, virtualization takes important role in order to give
I have realized that some simple routing problems started to be not solved easily and not clearly understood by my technical friends in our company. Because of that, I decided to explain what traceroute means in order to help them.The reason I chose to add "Indeed" in my headline is that traceroute protocol is a
