Dedicated Interconnect module

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

Prerequisites

1. Provisioning of four Dedicated Interconnect connections in the prj-interconnect project created in step 1-org under folder fldr-common.

Usage

1. Rename interconnect.tf.example to interconnect.tf in the shared envs folder in 3-networks-hub-and-spoke/envs/shared
2. Rename interconnect.auto.tfvars.example to interconnect.auto.tfvars in the shared envs folder in 3-networks-hub-and-spoke/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. The candidate subnetworks and vlan_tag8021q variables can be set to null to allow the interconnect module to auto generate these values.
