How to configure VPC peering in AWS? 

Normally network traffic blocked between VPCs.A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IP addresses.

You can create a VPC peering connection between your own VPCs, or with a VPC in another AWS account. In both cases, the VPCs must be in the same region.

In this article we will see 2 scenarios , First create a VPC peering connection within same AWS accout , and other scenario is creating VPC peering with another AWS account VPC.

Remember VPC address should not overlap

1.VPC Peering with same account same region. Now we have 2 VPCs findout-prod 10.0.0.0/16 and findout-dev 20.0.0.0/16.Now lets create VPC peering between these 2 VPCs.

Scenario 1:

In VPC Dashboard . Already VPC created.

In VPC dashboard select peering connection

Click “create Peering connection”

Select findout-dev as requester  . That you can choose.

Click Create peering connection . Now VPC peering has been created.

Here you can find all the detail about peering connection.

Note : Here Requester and Accepter are same AWS account.But still you need to accept since different VPCs.

Click Yes , Accept request

Now the status vpc peering connection status turned to active . Once you make entry in route table 10.0.0.0/16 network can communicated with 20.0.0.0/16 network

Scenario2:

All the steps are same except one field. Instead of my account select Another AWS account and enter AWS account ID .

 

Thats all! Thanks.
