Creating and listing network and subnet with neutron

These sections walk you through creating your network and subnet and then listing them by using the neutron client.

Creating a network (neutron client)

To create a network, you specify a name for your network. After you create a network, copy its network ID. You use this ID to create a subnet and attach it to a port.

1. Create network with neutron request

   $ neutron net-create amp
   

   Positional arguments:

   • The network name. In this example, the name is amp.

   +----------------+--------------------------------------+
   | Field          | Value                                |
   +----------------+--------------------------------------+
   | admin_state_up | True                                 |
   | id             | 29f52c7e-6efd-4335-a14a-db77d32a2555 |
   | name           | amp                                  |
   | shared         | False                                |
   | status         | ACTIVE                               |
   | subnets        |                                      |
   | tenant_id      | 53501b3c25d34f8ea293c03298caed60     |
   +----------------+--------------------------------------+
   

2. Copy the ID value from the output. You will use this value when you create a subnet, provision your server, or perform other related activities. In this example, the ID is 29f52c7e-6efd-4335-a14a-db77d32a2555, but use the id from your response.

Creating a subnet (neutron client)

To create a subnet, you specify a network, an IP address, and a name for your subnet. After you create a subnet, copy its subnet ID for future reference.

1. Create subnet with neutron request

   $ neutron subnet-create --name Subamp /
     --ip-version 4 29f52c7e-6efd-4335-a14a-db77d32a2555 120.1.2.0/24
   

   Positional arguments:

   • name The subnet name. In this example, the name is Subamp.

   • ip-version The version of the subnet IP. In this example, the version is 4.

   • The network ID or name. In this example, we used the network ID 29f52c7e-6efd-4335-a14a-db77d32a2555.

   • The network CIDR. In this example, the CIDR is 120.1.2.0/24.

   | Field            | Value                                        |
   +------------------+----------------------------------------------+
   | allocation_pools | {"start": "120.1.2.1", "end": "120.1.2.254"} |
   | cidr             | 120.1.2.0/24                                 |
   | dns_nameservers  |                                              |
   | enable_dhcp      |                                              |
   | gateway_ip       |                                              |
   | host_routes      |                                              |
   | id               | 23e3059e-4f39-4f7f-8cf2-c326e5de6c37         |
   | ip_version       | 4                                            |
   | name             | Subamp                                       |
   | network_id       | 29f52c7e-6efd-4335-a14a-db77d32a2555         |
   | tenant_id        | 53501b3c25d34f8ea293c03298caed60             |
   +------------------+----------------------------------------------+
   

2. Copy the id value from the output for future reference. In this example, the id is 23e3059e-4f39-4f7f-8cf2-c326e5de6c37, but use the id from your response.
