Platform For AI:Manage Lingjun VPDs

Overview of Lingjun VPDs

A Lingjun VPD consists of one virtual private router, at least one private CIDR block, and at least one subnet. The following content describes the components:

• A virtual private router is the hub of a Lingjun VPD. The virtual private router is an important functional component of the Lingjun VPD and is used to connect to each subnet of the Lingjun VPD. The virtual private router also serves as a gateway to connect the Lingjun VPD to other networks.

• After a Lingjun VPD is created, the system automatically creates a dedicated virtual private router. Each virtual private router is associated with a route table. A Lingjun VPD has only one system route table. You cannot manually create or delete the system route table of the Lingjun CIDR block.

• A subnet is a basic component of a Lingjun VPD and is used to connect to different Lingjun nodes. After a Lingjun VPD is created, you can divide the Lingjun CIDR block into one or more subnets. Different subnets in the same Lingjun VPD communicate with each other over the internal network.

Create a Lingjun VPD

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > VPDs.

3. On the VPDs page, click Create VPD.

4. On the Create VPD page, configure the parameters.

   1. Configure the Name and Node IPv4 CIDR Block parameters. We recommend that you use a standard private CIDR block and its subnet as the private CIDR block of a Lingjun cluster when you create a Lingjun VPD and its subnet. The following table describes the standard private CIDR blocks and their subnets. For more information, see the "Configure clusters and node groups" section of the Create a Lingjun cluster topic.

      CIDR block	Number of available private IP addresses (excluding reserved IP addresses)
      192.168.0.0/16	65,532
      172.16.0.0/12	1,048,572
      10.0.0.0/8	16,777,212

      Important

      • You cannot use 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, or 169.254.0.0/16 as a Lingjun CIDR block.

      • When you select a Lingjun VPD, the CIDR block cannot conflict with the CIDR blocks of other networks to which the Lingjun cluster is to be connected, such as CIDR blocks of virtual private clouds (VPCs) or data centers.

   2. In the Create Lingjun Subnet section, configure the Name and Zone parameters.

   3. Optional. Click Add to create another Lingjun subnet in the CIDR block.

5. Click OK. The Lingjun VPD is created.

   Important

   After you grant permissions to the peer account, the peer account can be used to load your Lingjun VPD into the Lingjun Hub instance of the peer account and connect the peer network to your network. Proceed with caution.

3. In the Cancel Authorization message, click Yes.

Create a Lingjun subnet

A Lingjun subnet is a basic component of a Lingjun VPD. Lingjun nodes cannot be directly deployed in a Lingjun VPD and must be deployed in the subnets of the Lingjun VPD. The IP address range of a Lingjun subnet must be a proper subset of the Lingjun CIDR block to which the Lingjun subnet belongs, and the first IP address and the last three IP addresses of each Lingjun subnet are reserved IP addresses.

For example, if a CIDR block of a Lingjun VPD is 192.168.0.0/16, the IP address range of a Lingjun subnet of the Lingjun CIDR block must be a proper subset of 192.168.0.0/16, which can be 192.168.0.0/17 to 192.168.0.0/29. If a Lingjun subnet is 192.168.1.0/24, the following IP addresses are reserved by the system: 192.168.1.0, 192.168.1.253, 192.168.1.254, and 192.168.1.255.

1. In the left-side navigation pane, choose Network Resources > Lingjun Subnets.

2. On the Lingjun Subnets page, click Create Lingjun Subnet.

3. On the Create Lingjun Subnet page, configure parameters such as Name and VPD.

4. Click OK.

View the basic information about a Lingjun subnet

1. In the left-side navigation pane, choose Network Resources > Lingjun Subnets.

2. Search for the Lingjun subnet whose information you want to view by name or ID.

3. View the information about the Lingjun subnet, including the ID, name, the Lingjun VPD to which the Lingjun subnet belongs, and status.

   Note

   If OOB is displayed in the Instance ID/Name column of a subnet, the subnet is reserved for Cloud Parallel File Storage (CPFS). Each Lingjun VPD reserves two subnets for CPFS. For more information, see the "Configure networks" section of the Create a Lingjun cluster topic.

4. Click the ID of the subnet whose information you want to view. On the details page of the subnet, view the details of the subnet in the Basic Information and Lingjun Resources sections.

Create a secondary CIDR block for a Lingjun VPD

If the number of IP addresses in a Lingjun VPD does not meet your business requirements, you can create a secondary CIDR block for the Lingjun VPD.

Limits

• By default, you can create up to three secondary CIDR blocks in each region by using an Alibaba Cloud account. For more information about how to increase the quota of secondary CIDR blocks, see Manage quotas.

• A secondary CIDR block cannot start with 0. The subnet mask can be 8 to 28 bits in length.

• The following CIDR blocks cannot be used as a secondary CIDR block of a Lingjun VPD: 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, and 169.254.0.0/16.

• A secondary IPv4 CIDR block cannot conflict with the primary IPv4 CIDR block or the created secondary IPv4 CIDR blocks of a Lingjun VPD. For example, you cannot create the following CIDR blocks as secondary IPv4 CIDR blocks if the primary IPv4 CIDR block of a Lingjun VPD is 192.168.0.0/16:

  • A CIDR block whose IP address range is the same as that of 192.168.0.0/16.

  • A CIDR block whose IP address range is larger than that of 192.168.0.0/16, such as 192.168.0.0/8.

  • A CIDR block whose IP address range is smaller than that of 192.168.0.0/16, such as 192.168.0.0/24.
