If you want to practice with EVPN in a non-Juniper environment I think
it works on the Cumulus Linux free/demo VM and probably some others
like Cisco xrv9k I believe, maybe the latest vMX supports it too?

Yeah EVPN has control-plane level MAC learning; from a high level
imagine it like a typical layer 3 VPN with IP prefixes being sent in
BGP UPDATES just that MACs are sent instead.
