====== Proxmox EVPN Test ======

Stand: 2024-04-27

Ziel: Proxmox EVPN ausprobieren

Proxmox-Cluster aus zwei Nodes:

  * pvetest01, 10.99.42.101
  * pvetest02, 10.99.42.102

Zusaetzlich gibt es einen BGP Router gegenueber dem die Nodes die IPs der Gaeste announcen sollen:

  * pvetest-bgp, 10.99.42.104
