Jeroen Van Bemmel created another interesting netlab topology: EVPN/VXLAN between SR Linux fabric and FRR on Linux hosts based on his work implementing VRFs, VXLAN, and EVPN on FRR in netlab release 1.3.1. Bonus point: he also described how to do multi-vendor interoperability testing with netlab. If only he wouldn’t be publishing his articles on a platform that’s almost as user-data-craving as Google.

Hey guys, recently I have started using FRR/routing in my test environment as docker containers on top of GNS3. As this dockers are very light weight, u can spin many router's provided u have a script to build the connections and configure them.

VXLAN est un protocole réseau pour transporter du trafic L2 au-dessus d'un réseau IP. BGP EVPN est une des options de déploiement.

In the ever-evolving landscape of network virtualization, Ethernet VPN (EVPN) and Virtual Extensible LAN (VXLAN) have emerged as powerful technologies for creating scalable and efficient network overlays. EVPN, combined with VXLAN, offers robust support f

In my previous posts We check how the pod networking and How Kubernetes use services for loadbalancing. Now we check how the diferente Networking solutions works. How Theas solutins link the kubernetes nodes together.

This article will cover some of the basics of OpenVswitch/OVNKubernetes in relation to learning the path that packets take between pods and also how services work.  This article will end with a cheat-sheet on how to use OpenVswitch/OVNKubernetes for troubleshooting purposes. I will give credit to the following
