1 gateway node
^^^^^^^^^^^^^^
In this example, we'll use only 1 proxmox node as exit gateway. (node1)
-This node have a simple default gw in the vrf to the external router (no bgp between router and node1)
-and announce this default gw to other proxmox nodes.

multiple gateway nodes
^^^^^^^^^^^^^^^^^^^^^^
In this example, all nodes will be used as exit gateway. (But you can use only 2 nodes if you want)
-All nodes have a simple default gw in the vrf to the external router (no bgp between router and node1)
-and announce this default gw.
+All nodes have a a default gw to the external router (192.168.0.254) (no bgp between router and node1)
+and announce this default gw in the vrf (default originate)
The external router have ecmp routes to all proxmox nodes.(balancing).
If the router send the packet to a wrong node (vm is not on this node), this node will route through
vxlan the packet to final destination.
