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-{p|n|d}-shared-{base|restricted} under corresponding environment's folder and prj-c-dns-hub under the folder fldr-common.

Usage

1. Rename partner_interconnect.tf.example to partner_interconnect.tf in the shared envs folder in 3-networks-dual-svpc/envs/shared
2. Rename partner_interconnect.auto.tfvars.example to partner_interconnect.auto.tfvars in the shared envs folder in 3-networks-dual-svpc/envs/shared
3. Update the file interconnect.tf with values that are valid for your environment for the interconnects, locations, candidate subnetworks, vlan_tag8021q and peer info.
4. Rename partner_interconnect.tf.example to partner_interconnect.tf in the base-env folder in 3-networks-dual-svpc/modules/base_env .
5. Update the enable_partner_interconnect to true in each main.tf file in the environment folder in 3-networks-dual-svpc/envs/<environment> .
6. Update the file partner_interconnect.tf with values that are valid for your environment for the VLAN attachments, locations.
