Step 1: Create a VPC

Scenarios

A VPC provides an isolated virtual network for ECSs. You can configure and manage the network as required.

You can create a VPC by following the procedure provided in this section. Then, create subnets, security groups, and assign EIPs by following the procedure provided in subsequent sections based on your actual network requirements.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and choose Network > Virtual Private Cloud.

    The Virtual Private Cloud page is displayed.

  3. Click Create VPC.
  4. On the Create VPC page, set parameters as prompted.

    A default subnet will be created together with a VPC and you can also click Add Subnet to create more subnets for the VPC.

    VPC-001

    Basic Information

    IPv4 CIDR Block

    The CIDR block of the VPC. The CIDR block of a subnet can be the same as the CIDR block for the VPC (for a single subnet in the VPC) or a subset of the CIDR block for the VPC (for multiple subnets in the VPC).

    The following CIDR blocks are supported:

    • 10.0.0.0/8-24
    • 172.16.0.0/12-24
    • 192.168.0.0/16-24

    192.168.0.0/16

    Basic Information

    Advanced Settings

    Click the drop-down arrow to set advanced VPC parameters.

    Retain the default settings.

    The name can contain a maximum of 64 characters, which may consist of letters, digits, underscores (_), hyphens (-), and periods (.). The name cannot contain spaces.

    Subnet-001

    Default Subnet

    IPv4 CIDR Block

    The CIDR block for the subnet. This value must be within the VPC CIDR block.

    192.168.0.0/24

    Default Subnet

    IPv6 CIDR Block

    Specifies whether to set IPv6 CIDR Block to Enable.

    After the IPv6 function is enabled, the system automatically assigns an IPv6 CIDR block to the created subnet. Currently, the IPv6 CIDR block cannot be customized. IPv6 cannot be disabled after the subnet is created.
