+# Configuring Landing Zone with Account Base DA to create CBR VPC Zone
+
+This tutorial provides step-by-step instructions for using the  IBM Cloud Account Infrastructure Base Deployment Architecture to provision a Context-Based Restriction (CBR) VPC zone and configure it with Landing Zone.
+
+## Prerequisites
+
+- IBM Cloud account with administrative permissions
+
+## Step 1: Deploy the Account Infrastructure Base Deployment Architecture
+
+1. Navigate to the IBM Cloud Catalog using this URL:
+   [Cloud automation for account configuration](https://cloud.ibm.com/catalog/7a4d68b4-cf8b-40cd-a3d1-f49aff526eb3/architecture/deploy-arch-ibm-account-infra-base-63641cec-6093-4b4f-b7b0-98d2f4185cd6-global?kind=terraform&format=terraform&version=93c7f855-881d-459b-8999-4567a4883f57-global)
+
+2. Click on **Add to project** to start the deployment process
+
+3. Configure the deployment parameters:
+   - Enter the name for the project
+   - Enter the description (optional)
+   - Enter the configuration name
+   - Select the region
+   - Select the resource group
+
+4. Review your configuration and click **Create**
+
+5. Configure the required variables present under **security**, **required** and **optional** sections.
+
+6. Click on deploy.
+
+## Step 2: Retrieve the CBR VPC Zone ID
+
+To access the CBR Zone ID, which becomes available as an output after the Account Base DA deployment completes -
+
+1. Navigate to Account Infrastructure Base deployment and select the configuration as shown in the reference image below.
+![Projects Account Infrastructure Base Deployment](https://raw.githubusercontent.com/terraform-ibm-modules/terraform-ibm-landing-zone/main/reference-architectures/infra-base-deployed.png)
+
+2.In the outputs section, locate the output variable named `cbr_map_vpc_zoneid` and copy the `zone_id` value as illustrated below.

+
+## Step 3:  Configure Landing Zone with the CBR Zone ID
+
+To properly configure landing zone with the retrieved CBR Zone ID -
+
+1. Select the appropriate landing zone configuration from one of the following options:
+   - [Red Hat OpenShift Container Platform on VPC landing zone](https://cloud.ibm.com/catalog/architecture/deploy-arch-ibm-slz-ocp-95fccffc-ae3b-42df-b6d9-80be5914d852-global)
+   - [VPC landing zone](https://cloud.ibm.com/catalog/architecture/deploy-arch-ibm-slz-vpc-9fc0fa64-27af-4fed-9dce-47b3640ba739-global)
+   - [VSI on VPC landing zone](https://cloud.ibm.com/catalog/architecture/deploy-arch-ibm-slz-vsi-ef663980-4c71-4fac-af4f-4a510a9bcf68-global)
+
+2. Configure the required variables present under **security**, **required** and **optional** sections.
+
+3. Within the **optional** section, locate the field labeled `existing_vpc_cbr_zone_id` and paste the `zone_id` value copied in step 2, as shown below.
+![Adding CBR VPC Zone ID](https://raw.githubusercontent.com/terraform-ibm-modules/terraform-ibm-landing-zone/main/reference-architectures/existing_vpc_cbr_zone_id.png)
+
+4. Click on deploy.
+
+5. Once deployed, CBR VPC zone will contain the required VPCs IDs as shown below.
