Basic Setup for VPC Peering

What is VPC Peering?
 - VPC peering  is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses.

-You can create a VPC peering connection between your own VPCs, or with a VPC in another AWS account.

-The VPCs can be in different regions (also known as an inter-region VPC peering connection).

Setup: VPC Peering Connection

-Create two VPCs :-
-VPC A (CIDR: 10.0.1.0/16) and
-VPC B (CIDR: 10.2.0.0/16).
 -Create subnets for VPCs and also you can edit the routing table if required.

-Go to the “Peering Connections” in the AWS Console


Click on “Create Peering connection” and configure the peering

           VPCs are in the same account.
