1.4. Defining the Scenario
The scenario for this guide is to create an Overcloud with an isolated network that uses IPv6. The guide aims to achieve this objective through network isolation configured using Heat templates and environment files. This scenario also provides certain variants to these Heat templates and environment files to demonstrate specific differences in configuration.
In this scenario, the Undercloud still uses IPv4 connectivity for PXE boot, introspection, deployment, and other services.
This guide uses a scenario similar to the Advanced Overcloud scenario in the Director Installation and Usage guide. The main difference is the omission of the Ceph Storage nodes.
For more information about this scenario, see the Director Installation and Usage guide.
This guide uses the 2001:DB8::/32 IPv6 prefix for documentation purposes as defined in RFC 3849. Make sure to substitute these example addresses for IPv6 addresses from your own network.
