Partner Interconnect module

This module implements the recommendation proposed in Establishing 99.99% Availability for Partner Interconnect.

Prerequisites

1. Provisioning of four VLAN attachments in the Hub project in the specified environment. That would be the prj-c-{base|restricted}-net-hub under the folder fldr-common in case of Hub and Spoke architecture.

Without Hub and Spoke enabled VLAN attachments will be created in prj-{p|n|d}-shared-{base|restricted} under corresponding environment's folder.

Usage

1. Rename partner_interconnect.tf.example to partner_interconnect.tf in the environment folder in 3-networks-hub-and-spoke/modules/base_env .
2. Update the enable_partner_interconnect to true in each main.tf file in the environment folder in 3-networks-hub-and-spoke/envs/<environment> .
3. Update the file partner_interconnect.tf with values that are valid for your environment for the VLAN attachments, locations.

Inputs
