How Many Local and Remote Subnets Can I Add to a VPN? Why Is an Error Message Displayed When I Update the Local Subnet by Specifying a CIDR Block?

  • You can configure up to 5 local subnets. The product of the number of local subnets and the number of remote subnets cannot exceed 225.
  • A VPC delivers VPC subnet routes based on the remote subnets of the VPN connection, remote subnets of the Direct Connect connection, and subnets of the VPC peering connection. Each subnet has one subnet route.
  • The number of VPC subnet routes cannot exceed 200. That is, the total number of remote subnets of the VPN connection, remote subnets of the Direct Connect connection, subnets of the VPC peering connection, and custom routes in a VPC cannot exceed 200.
