For the cloud to cloud replications, you can modify the automatically discovered network settings of the vApp or virtual machine. After a migration, failover, or a test failover, VMware Cloud Director Availability attaches the selected network settings in the target cloud site.

For the cloud to cloud replications, the network settings are provided as vApp > Network > NIC and you modify the network settings at the network level.
Since VMware Cloud Director Availability 4.4, a reversed replication now creates the following auto-resolved and original mappings for the vApp networks:
Table 1. Reversed Replication vApp Network Mappings
Original Network Mapping Reverse Replication Network Mapping
If no destination network match for the reversed replication network is found. No change. Keep the auto-resolved mapping of the source networks.
Alternatively, if multiple source networks connect to one destination network.
If a matching destination network for the reversed replication network is found. Reverse the original network mapping, preserving the protected vApp configuration for connection to target networks.

Prerequisites

  • Verify that VMware Cloud Director Availability 4.4 or later is deployed in both cloud sites for preserving the original network settings of the protected vApps after reversing the replication.
  • Verify that you can access VMware Cloud Director Availability as a tenant or as a service provider. For more information, see Accessing VMware Cloud Director Availability.

Procedure

  1. Under Incoming Replications > from Cloud, click vApp or VM
  2. Select the cloud to cloud replications for which you want to view the discovered network settings and click All actions > Network settings.
  3. In the Network Settings window, configure the target network settings of the selected replications.
    Table 2. vApp Network Settings Configuration for Replications from Cloud to Cloud
    Option Description
    Source vApp networks See the name of the vApps, their networks, and the virtual machine network interface cards (NIC).
    Connect to target orgVDC network Select the discovered network that the vApp connects to in the target site after a migration, failover, or test failover:
    • Network name select to replicate the source vApp network in the target site and connect the target vApp to the selected orgVDC Network name in the target site.
    • None select to replicate the source vApp networks without connecting the target vApp to any network in the target site.
    • Mixed selected when multiple vApps, virtual machines, or NICs are connected to different networks.
    Connected Select to connect the selected NICs to the vApp network.
    Primary NIC See the discovered primary NIC for each virtual machine in the vApp.
    MAC address See the MAC address for each NIC in the virtual machines in the vApp.
    Reset MAC Select to reset the MAC address of the highlighted NIC in the target site.
    IP mode
    • None is selected by default, no IP addressing mode is specified.
    • Mixed is selected when multiple NICs have different network configurations.
    • Static - IP Pool select to obtain an IP address for the highlighted NIC from an IP pool in the target network.
    • DHCP select to obtain an IP address for the highlighted NIC from the target network DHCP server.
    • Static - Manual select to enter a static IP address to the highlighted NIC.
    IP address Set the IP address of each virtual machine or NIC under the vApp.
    Tip: When in Connect to target orgVDC network you select None, and you select Connected, the virtual machine NICs are enabled for communication in the target vApp network. The target vApp network is kept isolated and is not connected to the OrgVDC network in the target site.
    Table 3. Virtual Machine Network Settings Configuration for Replications from Cloud to Cloud
    Option Description
    VMs See the name of the virtual machines and their network interface cards (NIC).
    Source vApp networks See the name of the vApp network that the virtual machine connects to in the source site.
    Connected Select to connect the selected NICs in the virtual machine to the target cloud site network.
    Primary NIC See the discovered primary NIC for the virtual machine.
    MAC Address See the MAC address for each NIC in each virtual machine in the selected replication.
    Reset MAC Select to reset the MAC address of the highlighted NIC of the virtual machine in the target site.
    IP mode
    • None is selected by default, no IP addressing mode is specified.
    • Mixed is selected when multiple NICs have different network configurations.
    • Static - IP Pool select to obtain an IP address from an IP pool in the target network. To commit the IP address changes to the guest OS, select Guest customization.
    • DHCP select to obtain an IP address from the target network DHCP server.
    • Static - Manual select to enter a static IP address. To commit the IP address changes to the guest OS, select Guest customization.
    IP address When Static - Manual from the IP Mode drop-down menu is selected, enter a static IPv4 address to the highlighted NIC. To commit the IP address changes to the guest OS, select Guest customization.
    Guest customization Select to commit the IP address changes to the guest OS.
  4. For the selected cloud to cloud replications, to confirm the target network settings, click Apply.

Results

After a successful cloud to cloud migration, failover, or a test failover, VMware Cloud Director Availability replicates the workload to the target cloud site. Then VMware Cloud Director Availability attaches the selected network settings to the target vApp or virtual machine.
