Explanation:
The user can create subnets as per the requirement within a VPC. If the user wants to connect VPC from his own data centre, he can setup a public and VPN only subnet which uses hardware VPN access to connect with his data centre. When the user has configured this setup with Wizard, it will create a virtual private gateway to route all traffic of the VPN subnet. Here are the valid entries for the main route table in this scenario: Destination:
0.0.0.0/0 & Target: vgw-12345 (To route all internet traffic to the VPN gateway.
Destination: 20.0.0.0/16 & Target: local (To allow local routing in VPC.
