A company has two VPCs (VPC1 and VPC2) configured in two different AWS Regions that are part of the same AWS account. There is an active VPC peering connection between the VPCs that has been configured in the route tables for both VPCs. The database is present in VPC1 and the access to the database instance is controlled through a security group defined in VPC1. VPC2 consists of an Auto Scaling group that scales in/out any Amazon EC2 instances based on the CPU usage. Each instance launched as part of the Auto Scaling group belongs to a security group defined specifically for the Auto Scaling group. The launched instances need seamless access to the database instance present in VPC1. Which additional step is needed for the solution to work if the route tables are already configured for VPC peering?
