Create a Provider Network with NSX-T Data Center

With NSX-T Data Center networking, you can create a VLAN-based provider network.

Prerequisites

• Define a VLAN for the provider network and record its ID.
• To use DHCP with VM form-factor NSX Edge nodes, enable forged transmit and promiscuous mode on the port group containing the edge nodes. For instructions, see Configure the Security Policy for a Distributed Port Group or Distributed Port.

Procedure

1. Log in to the VMware Integrated OpenStack dashboard as a cloud administrator.
2. Select the admin project from the drop-down menu in the title bar.
3. Select Admin > Network > Networks.
4. Click Create Network and configure the provider network.

   Option	Description
   Name	Enter a name for the network.
   Project	Select the desired project from the drop-down menu.
   Provider Network Type	Select VLAN from the drop-down menu.
   Physical Network	Enter the UUID of the VLAN transport zone.
   Segmentation ID	Enter the VLAN ID defined for the provider network.

5. Select Enable Admin State and Create Subnet.
6. If you want multiple projects to use the provider network, select Shared.
7. Click Next and configure the subnet.

   Option	Description
   Subnet Name	Enter a name for the subnet.
   Network Address	Enter the IP address range for the subnet in CIDR format (for example, 192.0.2.0/24).
   IP Version	Select IPv4 or IPv6.
   Gateway IP	Enter the gateway IP address. If you do not enter a value, the first IP address in the subnet is used. If you do not want a gateway on the subnet, select Disable Gateway.

8. (Optional) Configure additional settings for the subnet.
   1. Under Allocation Pools, enter IP address pools from which to allocate the IP addresses of virtual machines created on the network. Enter pools as two IP addresses separated by a comma (for example, 192.0.2.10,192.0.2.15). If you do not specify any IP address pools, the entire subnet is available for allocation.
   2. Under DNS Name Servers, enter the IP address of one or more DNS servers to use on the subnet.
   3. Under Host Routes, enter additional routes to advertise to the hosts on the subnet. Enter routes as the destination IP address in CIDR format and the next hop separated by a comma (for example, 192.0.2.0/24,192.51.100.1).
9. Click Create.
