Create a VPC private network

  1. On the top navigation bar, click Cloud Services, and then select VPCs from the Network menu.

  1. From the left navigation pane, select Private Networks.

  1. Click Create.

  1. Configure VPC private network parameters.

If you select Default Configuration in the Advanced Configuration area, the advanced features are not supported and the system assigns a segment ID automatically.

Table-1 Creating a VPC private network

Parameter

Description

Basic Info

Name

Specify the private network name.

Organization

Specify the organization that uses the network.

VPC

Select a VPC.

Network Egress

Select a network egress. The system displays available AZs based on the selected network egress.

To view detailed information about the selected network egress, including compute node and Nova AZ, click Details.

AZs

Select AZs. Compute nodes in the selected AZs can communicate with each other.

Sharing

Select whether to turn on or off network sharing. This parameter is configurable when you have specified the root organization

Shared Organization

Select the organizations that can share the network. By default, all organizations can use the network. If you select Specify Organization, only the specified organizations can use the network.

IPv4/IPv6

Enable or disable IPv4/IPv6. By default, the IPv4 and IPv6 settings are consistent with the settings of the selected VPC.

CIDR

Specify the network segment.

Gateway Address

Specify the gateway address. If you do not specify a gateway address, the system assigns the first address of the network segment as the gateway address. For example, if the segment is 192.168.0.0/24, the automatically assigned gateway address is 192.168.0.1.

Advanced Configuration

Segment ID

Specify the VLAN ID or VXLAN ID.

This value range depends on the selected network egress.

MTU

Specify the MTU in the range of 1280 to 9000. This parameter is available only when the MTU feature is enabled. For information, see MTU configuration in "Network configuration."

CAUTION Caution:

An inappropriate MTU value affects services and can even cause traffic interruption. Make sure you set and edit the MTU according to the actual network condition.

DHCP

Enable or disable DHCP.

With DHCP enabled, the system assigns IP addresses to cloud hosts in the private network automatically after the cloud hosts start up.

With DHCP disabled, you must manually specify an IP address to a cloud host at host creation or log in to the host's console to specify an IP address after host creation.

IPv6 Configuration Mode

This parameter is configurable only when IPv6 is enabled. By default, the Static IP mode is used. Options are:

  • Static IP—The host IP, mask, and network gateway are configured manually. This method is mainly used for router interfaces and typically not used for hosts. If Static IP is specified, all IPv6 auto configurations are disabled.

  • SLAAC—A node obtains an IPv6 prefix from the RA messages sent from the router and uses the interface identifier as the suffix to form an IPv6 address.

  • DHCPv6-Stateless—Obtain an IPv6 address through SLAAC and other information from a DHCPv6 server.

  • DHCPv6-Stateful—Obtain all interface parameters from a DHCPv6 server.

Available Addresses

Specify the range of IP address that can be assigned to cloud hosts.

DNS

Specify the IP address of the DNS server. You can specify a DNS server configured on the Cloud Service > Networks > DNS page or specify an existing third-party DNS server.

To provide the DNS service for cloud hosts, you must change the DNS server address of the VPC private network.

  • If the system acts as the DNS server, use the system VIP as the DNS server address.

  • If the cloud hosts have been created, add the nameserver parameter to the /etc/resolv.conf file and use the system VIP as its IP.

Routes

Configure static routes for cloud hosts in the private network.
