<li> At step 3, follow the [https://www.rdoproject.org/networking/neutron-with-existing-external-network/ Neutron with existing network guidance]:</li>
<ul>
<li> Use command <code>packstack --cinder-volumes-create=y --cinder-volumes-size=100G --provision-demo=n --os-heat-install=y --os-ceilometer-install=y --os-horizon-ssl=n --keystone-admin-passwd={set password} --os-neutron-ml2-mechanism-drivers=openvswitch --os-neutron-ml2-tenant-network-types=vxlan --os-neutron-ml2-type-drivers=vxlan,flat,vlan --os-neutron-l2-agent=openvswitch --os-neutron-ovs-bridge-interfaces=br-ex:eth0 --nova-libvirt-virt-type=kvm</code> (replace ''eth0'' with appropriate interface)</li>
<li> Skip down to ''Now, create the external network with Neutron.'' and follow guidance.</li>
<li> Next move to ''Then create a router and set its gateway using the external network...'' and follow remaining guidance.</li>
