There are at least 3 types of solutions I'm aware of: 1) Using VLANs and physical or virtual-machine appliances that route packets between VLANs. Tutorial: http://developer.rackspace.com/blog/neutron-networking-vlan-provider-networks.html
2) Using an L2 overlay and virtual machines that route packets between VLANs. (e.g. OVS + neutron virtual-router) Tutorial: http://developer.rackspace.com/blog/neutron-networking-simple-flat-network.html 3) Using an L3 overlay that implements a distributed router. (e.g. OpenContrail) Unfortunately i don't know of a tutorial that is has nice as the ones above... but you can glean some useful information from: https://github.com/dsetia/devstack/blob/master/contrail/README and http://pedrormarques.wordpress.com/2013/11/14/using-devstack-plus-opencontrail/ Pedro.
