This is a post that takes the previous Nexus EVPN VXLAN Fabric and the Nexus EVPN VXLAN Fabric using Ansible posts, and uses the GitLab pipeline to perform the automation. In a previous post, I have walked through the setting up GitLab for CI/CD pipelines with external runners. For this GitLab project, I am using […]

In this post, I will outline the configuration for a VXLAN fabric using BGP EVPN and OSPF as the underlay. This is similar to my previous Arista project and VXLAN project. The topology of this post will be four switches and six clients. For the configuration, I will go section by section for each device

I have been over the automatic creation of the VXLAN topology in the previous post. However, this stopped at the creation of the topology only. If in the future I wanted to add a new spine or leaf switch, this could be done, but the other switches wouldn’t be aware as they would also need

This is going to follow on from the previous post to get a basic three switch topology up and running with VXLAN. This time however, instead of doing more VXLAN I will concentrate on a way to automate the adding of spine and leaf switches to the fabric.The purpose of this automation piece is to
