Arista Validated Designs: Transforming the Role of Network Engineers

In the fast-paced and interconnected world of technology, network engineers play a crucial role in ensuring seamless connectivity, efficient data transfer, and robust network performance. As the demands on networks continue to grow, the importance of well-designed and optimized network infrastructure becomes increasingly evident. Arista Validated Designs (AVD) have emerged

Hunting Duplicate IP Addresses Using "Arping" on Arista Switches

Originally written by Kevin Giusti for the WAN Dynamics site. Hosting to keep the knowledge alive! As network operators, we often face the daunting task of troubleshooting duplicate IP addresses on the network. This is an age-old issue that can turn into a tedious and time-consuming process if not handled

Originally written by Kevin Giusti for the WAN Dynamics site. Hosting to keep the knowledge alive! It’s the year 2022 so can we collectively agree to stop using insecure protocols like FTP and TFTP to transfer files to and from your network devices? One of the many advantages of

EOS Upgrade With Ansible

EOS Upgrade With Ansible

Originally written by Kevin Giusti for the WAN Dynamics site. Hosting to keep the knowledge alive! Even though managing Arista switches is pretty great, sometimes performing things like software upgrades can be tedious and boring, especially when there are a lot of switches to upgrade at a time. Here at

Why Arista + Ansible Is A Perfect Marriage For Network Automation

Why Arista + Ansible Is A Perfect Marriage For Network Automation

WAN Dynamics has been spending a lot more time with Ansible when deploying and managing customer network environments. Arista is one of our closest partners so we use their gear a lot and have come to realize a few truths to automating Arista Extensible Operating System (EOS) environments with Ansible.

Dual Datacenter DMZ With VXLAN, VARP, VRF & OSPF with Arista Networks

Dual Datacenter DMZ With VXLAN, VARP, VRF & OSPF with Arista Networks

Based on business needs, dual datacenter networks will evolve from an “active/standby” disaster recovery configuration that has an active primary datacenter carrying workloads and a site sitting on standby over to a “active/active” datacenter environment with workloads spread across both centers. Typically in the datacenters there will be
