Connect 8 RasPis through eno2

I have 8 RasPi 3’s witch are conected to a port called eno2.
My system runs debian bulleye.
It runs OVN and creates a lan with address range 168.192.20.0/24. Seems to work well for the 6 containers I have instaled on incus (they run alpine linux).
Now I wish to register the 8 raspi’s on the same network.
My approach has been:
nmcli connection delete pi-bridge
ip link add name pi-bridge type bridge
ip link set dev pi-bridge up
ip link set dev eno2 up
ip link set dev eno2 master pi-bridge
net.ipv4.ip_forward 1
incus network set pi-cluster bridge.external_interfaces=pi-bridge
incus network set pi-cluster ipv4.nat=true
incus network set pi-cluster bridge.mtu=1500

But no joy. How would you go about this?
