I got stuck at the eVPN BGP setup evpn neighbors will not come up underlay eBGP between spien and leaf is established. I’ll have a complete configuration workbook attached at the end of this blog. I won’t be covering special use cases or every possible configuration parameter, but hopefully this is a good start to get you going on to super deep dives.
While most of this configuration will function in production networks, I highly advise first building something out virtually to do testing (GNS3, Vagrant, what-have-you). Lastly, I’ll give an example configuration of L2VXLAN (EVPN Type-2) and 元VXLAN (EVPN Type-5). Next, we’ll configure the EVPN overlay and VTEPs. We will start with the initial configuration of underlay components, such as MLAG and underlay BGP. Each pair of Leafs will form a VXLAN Tunnel Endpoint (VTEP). In this topology, we have 2 Spines and 8 Leafs. In this article, I want to walk through a configuration example. Since then, I’ve learned how valuable it is in Service Provider networks as well, but I’ll save that for another day. In the previous article, I discussed some terminologies and behavior of EVPN and the reason why EVPN is valuable in Data Center and Campus networks. This is a follow-up to my previous article, Arista BGP EVPN Overiew and Concepts.
