You can create a stretched network across all virtual data centers that are participating in a data center group.
You can add only an IPv4 stretched network.
This operation requires the predefined Organization Administrator role or a role with the Organization VDC Network: Edit Properties right.
- From the main menu (), select Datacenter Groups.
The list of data center groups displays in a card view.
- In the card of the target data center group, click Details.
You are redirected to the Network Topology view for this data center group. You can see a diagram of the current network topology, which depicts the participating virtual data centers with their network fault domains, the egress points if configured, and the traffic routes.
- In the left panel, click Stretched Networks.
The list of stretched networks displays in a grid view.
- Click Add.
- Enter a name and, optionally, a description for the new stretched network.
- Enter the network Classless Inter-Domain Routing (CIDR) settings, and click Create.
Use the format network_gateway_IP_address/subnet_prefix_length, for example, 184.108.40.206/24.
You can see the newly created network in the list of stretched network for the data center group.
An organization virtual data center network of cross-VDC routing type is created for each participating virtual data center. You can see the newly created networks in the Datacenters view of the participating virtual data centers by clicking Networks. If a virtual machine or vApp connects to such an organization virtual data center network, this virtual machine or vApp connects to the stretched network.
What to do next
For DNS and DHCP configurations for virtual machines attached to a stretched network, you can use the vCloud OpenAPI. To examine the vCloud OpenAPI documentation, go to https://vCloud_Director_IP_address_or_host_name/docs. To view code samples and test vCloud OpenAPI calls, go to https://vCloud_Director_IP_address_or_host_name/api-explorer?scope=organization_name.
