Ultimate OpenStack Juno Guide
This is a Quick Guide to deploy OpenStack Juno on top of Ubuntu 14.04.2, it is IPv6-Only (almost)! But, it can be used to deploy a IPv4-Only environment, just replace the IPs with sed.
It is compliant with OpenStack's official documentation (docs.openstack.org/juno).
The Project's (old "Tenant" terminology) subnets are based on Neutron, with ML2 plugin and Single Flat Network topology, Dual-Stacked, while of course, IPv4 is optional. The topology VLAN Provider Networks are also supported on this guide, it is very similar with Single Flat Network.
The Single Flat Network is the simplest network topology supported by OpenStack. So, it is easier to understand and follow. Then, you can start using VLAN Provider Networks, which is basically something like a "Multi-(Single Flat Network)", where each "Flat LAN" resides on its own VLAN tag.
Finally, the IPv6 support on Neutron L3 Router is ready! With ML2 plugin, you can have a Dual-Stacked environment on top of a Single Flat Network / VLAN Provider Networks without using Neutron L3 Router at all (i.e. by using upstream routers)....
