OK, so after some 'delete' exercises
I managed to delete it;
root at controller2:/# neutron net-delete 3446e54b-346f-45e5-89a2-1ec4eef251ab
Deleted network: 3446e54b-346f-45e5-89a2-1ec4eef251ab
Now, there are no ports in use:
root at controller2:/# source admin-openrc.sh
root at controller2:/#
root at controller2:/# neutron port-list
root at controller2:/# source demo-openrc.sh
root at controller2:/#
root at controller2:/# neutron port-list
I've not altered config files yet, ( as to allow only gre)
So I'm just creating 'demo-net2'
root at controller2:/# neutron net-create demo-net2
Created a new network:

ok, then please adapt the tenent_network_types variable on your network node to just use gre first
