How to Setup AWS VPC Peering Connections: A Step-By-Step Guide

How VPC Peering Works: Multi-VPC Connections

AWS VPC Peering Latency

Step 1: Navigate to VPC Dashbaord

After Navigate to Console, you look into the following Console Home Page:

Select the VPC service in the search box.

Step 2: Create Virtual Private Network

Create 2 VPC networks with names myvpc1 and myvpc2.
Firstly, Click on the Create VPC button to create VPC.

Configure the VPC details as shown in the below screenshot.

Similarly define and create second vpc with name myvpc2. Ensure that the CIDR of myvpc1 and myvp2 doesn’t overlay.

Step 3: Select “Peering Connections”

Navigate to VPC Peering, and click on create VPC peering button.
Provide the accepter VPC name and receiver VPC name.

Step 3: Click “Create Peering Connection”

After creating the vpc peering connection, it will be in pending status .

Step 4: Accept Peering Connection

Now, from the myvpc2 aws account, go to vpc peering dashboard, click on the accept request and accept the peering connection.

Step 5: Successful VPC Peering Connection

After once the myvpc2 network accepts the request, the VPC peering connection will become active in status.

Step 6: Update Route Tables ( if necessary )

Ensure that the route tables for both VPCs are updated to include routes for each other’s CIDR blocks, pointing to the peering connection.

Step 7: Verify Connectivity

Now, Create an instance on each vpc and try on pinging the private IP of instance on each other instance.
If they are successfully pinging then you have established VPC peering successfully.

Sometimes we need to allow resources in different VPCs to exchange data based upon the architecture of the service. Regardless of any specific need, using VPC peering is a great way of extending your VPC design.

Note: When you start to have a lot of peering connections between multiple VPCs, in multiple regions, across multiple AWS accounts, managing the connections. When it starts to get difficult, it is time to start looking at moving the existing peering connections to Transit Gateway and managing the connections there.
