Create L2 templates

After you create subnets for the MOSK cluster as described in Create subnets, follow the procedure below to create L2 templates for different types of OpenStack nodes in the cluster.

See the following subsections for templates that implement the MOSK Reference Architecture: Networking. You may adjust the templates according to the requirements of your architecture using the last two subsections of this section. They explain mandatory parameters of the templates and supported configuration options.
