Basic Deployment

The basic procedure for deploying a VPC is as follows:
  1. Create an L2 public network and attach it to the corresponding cluster.
  2. Create an L3 public network.
  3. Create an L2 management network and attach it to the corresponding cluster.
  4. Create an L3 management network to communicate with physical resources, such as hosts, primary storages, and backup storages.
  5. Add a vRouter image.
  6. Create a vRouter offering.
  7. Create a VPC vRouter from the vRouter offering you created in the preceding step.
  8. Create an L2 private network and attach it to the corresponding cluster. This L2 private network is used to create an L3 VPC network (VPC Network-1).
  9. Specify a VPC vRouter to create an L3 VPC network (VPC Network-1). Note that the IP ranges cannot overlap.
  10. Create an L2 private network and attach it to the corresponding cluster. This L2 private network is used to create an L3 VPC network (VPC Network-2).
  11. Specify a VPC vRouter to create an L3 VPC network (VPC Network-2). Note that the IP ranges cannot overlap.
  12. Use VPC Network-1 and VPC Network-2 to create VM-1 and VM-2, respectively.
  13. Test the interoperability between VPC Network-1 and VPC Network-2.
Assume that your environment is as follows:
  1. Public Network
    Table 1. Configuration Information
    Public Network Configuration Information
    NIC em01
    VLAN ID No VLAN
    IP range 10.108.10.100~10.108.10.200
    Netmask 255.0.0.0
    Gateway 10.0.0.1
    DHCP IP 10.108.10.101
  2. Management Network
    Table 2. Configuration Information
    Management Network Configuration Information
    NIC em02
    VLAN ID No VLAN
    IP range 192.168.29.10~192.168.29.20
    Netmask 255.255.255.0
    Gateway 192.168.29.1
    Note:
    • For security and stability reasons, we recommend that you deploy an independent management network and separate it from the public networks.
    • The management network we mentioned here is the same as that in ZStack Private Cloud. That is, the management network is the network used to manage hosts, primary storages, and backup storages. If a management network was created before, you can use it directly.
  3. VPC Network-1
    Table 3. Configuration Information
    Private Network Configuration Information
    NIC em01
    VLAN ID 2800
    IP CIDR 192.168.10.0/24
    Gateway 192.168.10.1
    DHCP IP 192.168.10.2
  4. VPC Network-2
    Table 4. Configuration Information
    Private Network Configuration Information
    NIC em01
    VLAN ID 2900
    IP CIDR 192.168.11.0/24
    Gateway 192.168.11.1
    DHCP IP 192.168.11.2

To create a VPC in the Cloud, follow these steps:

  1. Create an L2 public network in the ZStack Private Cloud UI.
    In the navigation pane of the ZStack Private Cloud UI, choose Network Resource > L2 Network Resource > L2 Network. On the L2 Network page, click Create L2 Network. On the displayed Create L2 Network page, set the following parameters according to the Table 1:
    • Name: Enter a name for the L2 public network.
    • Description: Optional. Enter a description for the L2 public network.
    • Type: Select L2NoVlanNetwork.
    • Physical NIC: Enter em01.
    • Enable SR-IOV: Choose whether to enable SR-IOV. Here, leave this checkbox unselected.
    • Cluster: Select a cluster, for example, Cluster-1.
    Click OK. Then, an L2 public network will be created, as shown in Figure 1.
    Figure 1. Create L2 Network


  2. Create an L3 public network in the ZStack Private Cloud UI.
    In the navigation pane of the ZStack Private Cloud UI, choose Network Resource > L3 Network > Public Network. On the Public Network page, click Create Public Network. On the displayed Create Public Network page, set the following parameters according to the Table 1:
    • Name: Enter a name for the L3 public network.

    • Stop DHCP server: Choose whether to enable the DHCP service.
      Note:
      • By default, this checkbox is not selected, indicating that the DHCP service is enabled, and IP addresses will be automatically allocated to VM instances. In this case, you can customize a DHCP IP address, or let the system randomly specify a DHCP IP address.
      • If selected, the DHCP service will be disabled, indicating that VM instances that use this network cannot obtain IP addresses automatically, and need to be configured manually with IP addresses. In this case, you cannot customize the DHCP IP address. In addition, the system cannot randomly specify a DHCP IP address.
    • Add IP Range: Select the IPv4 IP address type and the IP range method.
      Note: ZStack supports both IPv4 and IPv6. You can choose to add an IP range or a CIDR. This tutorial takes the IPv4 IP address and IP range method as examples.
    • Start IP: Enter a start IP address, for example, 10.108.10.100.
    • End IP: Enter an end IP address, for example, 10.108.10.200.
    • Netmask: Enter a netmask, for example, 255.0.0.0.
    • Gateway: Enter a gateway, for example, 10.0.0.1.
    • DHCP IP: Optional. Set a DHCP IP address as needed.
      Note:
      • If you create an L3 network and enable the DHCP service for the first time, or if you add the first IP range for the L3 network of the enabled DHCP service, you can customize the DHCP IP address.
      • If the L3 network has a DHCP IP address, you cannot customize the DHCP IP address when you add an IP range.
      • The DHCP IP address can be included or excluded on the added IP range. However, the DHCP IP address must be within the CIDR to which the added IP range belongs, and must not be occupied.
      • The IP range specified within the start IP address and end IP address cannot contain IP addresses of the link-local address (169.254.0.0/16).
      • If not specified, the system will randomly specify an IP address within the IP range that you added.
    • DNS: Optional. Set a DNS, for example, 114.114.114.114.
    Click OK. Then, an L3 public network will be created, as shown in Figure 2.
