Azure Route Table

This feature creates an Azure Route Table with an option to create a Force Tunneling route. You need to associate this Route Table with any subnet that needs those special routing features.

Global versioning rule for Claranet Azure modules

Module version	Terraform version	AzureRM version

Usage

This module is optimized to work with the Claranet terraform-wrapper tool which set some terraform variables in the environment needed by this module. More details about variables set by the terraform-wrapper available in the documentation.
