As a prerequisite the deployment will need to have their VPN tunnels configured with all relevant VLANs, tunnels and routes ready to place on the host machines. I think that the host machine will also need to have ip_forward enabled:
echo 1 > /proc/sys/net/ipv4/ip_forward
On any host that will be part of the mesh will need a br-repl bridge created with the host-local IPs on it. Any tunnels/VLANs/etc that need to be on the host belong in this bridge. An example I wrote for the [host networking chapter][1]
