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.

2) Using an L2 overlay and virtual machines that route packets between VLANs. (e.g. OVS + neutron virtual-router)

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:
