Convention is for it to be a pipe, i.e. the second option. Usually the
tenant network will be its own VLAN and then an overlay network (e.g.
Geneve, VXLAN, etc) will create tenant networks on top of that VLAN
when each tenant requests with a command like `openstack network
create my_private_network`. On a default TripleO install you should be
able to source the overcloudrc and then run that command to create
these overlay networks.
