VXLAN-EVPN on Juniper reading only
A complete written course on vJunos-switch — ten sessions plus five lab guides, covering underlay, overlay, L2VNI and L3VNI, multi-tenancy, ESI multihoming, external connectivity and multi-site.
Why it was archived¶
The vJunos-switch labs proved unstable to run: booting four virtual forwarding planes concurrently on one host repeatedly failed, with nodes coming up degraded and commits hanging. Host resources weren't the constraint — roughly two nodes was the practical ceiling, which isn't enough for a spine-leaf fabric.
The hands-on path moved to Arista cEOS, which is a container, boots in minutes, and runs a full fabric on a laptop.
The theory is still good
EVPN route types, VXLAN encapsulation, route reflector design and multi-tenancy are protocol behaviour, not vendor behaviour. Those sessions read perfectly well alongside the current EVPN phase — only the configuration syntax differs.
What you shouldn't do is try to run the labs without a cloud VM. See cloud VM setup if you want to anyway.
