# Set up VPC Peering on AWS

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

## 1\. Prerequisites

* Unterminated TigerGraph Cloud Classic clusters on AWS

## 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**.

Choose AWS and enter a region such as `us-west-1`.

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

* **AWS Account ID**  
   * The ID of the VPC owner's AWS account.
* **Region**  
   * The region of the VPC you want to peer with.
* **VPC ID**  
   * The ID of the VPC from the AWS dashboard.
* **CIDR**  
   * CIDR-block of the peered VPC. You can also use an IPv6 CIDR here if your peered VPC has one.

Click **Initiate VPC Peering**.

### 2.2\. Accept VPC peering request

TigerGraph then sends a VPC peering connection to your VPC. Follow the steps below to accept the peering connection on your AWS VPC. See more in AWS's documentation on[Accepting VPC Peering Connections](https://docs.aws.amazon.com/vpc/latest/peering/create-vpc-peering-connection.md#accept-vpc-peering-connection).

1. Go to **VPC service** **Peering Connections** in the AWS web console
2. Accept the connection from the TigerGraph VPC

### 2.3\. Update route table for VPC peering connection

After accepting the peering request, you still need to update your route table for the peering connection.

To add a route for a VPC peering connection:

1. Open the Amazon VPC console at <https://console.aws.amazon.com/vpc/>.
2. In the navigation pane, choose **Route Tables**.
3. Select the checkbox next to the route table that's associated with the subnet in which your instance resides.
4. Choose **Actions** **Edit routes**.
5. Choose **Add route**.
6. For **Destination**, enter the CIDR block of the TigerGraph VPC you are peering with. You can find the CIDR block of the TigerGraph VPC at**Peering Connections** in the VPC service where you accepted the peering connection. There is a column "**Requester CIDRs**"**.**
7. For **Target**, select the VPC peering connection, and then choose **Save changes**.
