# Set up VPC Peering on GCP

This is a guide for setting up a VPC peering connection between your TigerGraph Cloud Classic VPC and another GCP VPC.

## 1\. Prerequisite

* At least one unterminated TigerGraph Cloud Classic cluster on GCP

## 2\. Procedure

### 2.1\. Initiate VPC Peering

Log into the cloud portal and navigate to the Network tab on the left. Click **Initiate VPC peering**.

Select Google Cloud and a region, then click **Next**.

In the Peer VPC section, fill in the information of the VPC that you hope to peer with:

* GCP Project ID
* VPC Name

Click **Initiate VPC Peering**.

### 2.2\. Create VPC peering connection from peered VPC to host VPC

Your TigerGraph VPC then creates a peering configuration to the VPC you hope to peer with. At this time, the peering connection will appear as **Inactive**. To complete the peering connection, your still need to create a matching peering configuration on your peered VPC to the TigerGraph VPC:

1. In the Google Cloud Console, go to the **VPC Network Peering** page.[Go to VPC Network Peering](https://console.cloud.google.com/networking/peering/list)
2. Click **Create connection**.
3. Click **Continue**.
4. Enter a **Name** for your peering connection.
5. Under **Your VPC network**, select a network you want to peer.
6. Select the TigerGraph network as the network to peer with.  
   * Select **In another project**. You will need to specify the project ID that includes the network you want to peer with and the name of the VPC network:  
         * Project ID:\`tgcloud-prod\`  
         * VPC network name: Name of your TigerGraph Cloud Classic VPC. You can find it in the **TigerGraph Cloud Classic portal** **Network tab** **VPC Peering** page. Choose `GCP` as the platform, and in the VPC column is the VPC name.
7. You can leave the other fields as they are (with only **Export subnet routes with public IP** selected) unless you need special configurations.
8. Click **Create**.

After creating the matching peering configuration, the status of your VPC connection should change to **Active** meaning the two VPCs are peered successfully.
